President’s Pen - Campbell Perrin

Greetings to members wherever you are,

whether in the cold South Island or the warmer

North Island, or in the Pacific Islands.

My role as President started in August 2013; it is

now a year on and what a year it has been!!

The year has gone so fast since I was elected

President and a lot of water has gone under the

bridge since then. Tough decisions have been

made during the year to move PMANZ into the

future. We hope you approve.

First up, and after some discussion and

investigation into the options available, the

council has placed advertising in August editions

of both, the NZ House & Garden and the Air NZ

In-flight magazine Kia Ora. Both publications

have a wide readership and are an excellent

medium to get the PMANZ brand out to a wider

audience.

Secondly, we have developed a new website and

thirdly, a PMANZ Facebook Page. We

encourage you to look at these, and please post

your ‘like’ on the PMANZ Facebook page. At this

stage we do not want Associate Members putting

their advertising on our Facebook page. This is

something we will look at in the future.

The PMANZ Council are exploring further options

to promote the PMANZ brand, now and in the

future.

Members that attended the Conference in

Auckland last year will recall receiving the Urban

Pest Management in Australia publication, and

then earlier this year, all members received the

Service Technician’s Field Manual, on renewal of

your membership. Council intends to keep

encouraging members to develop their own pest

management reference library by continuing to

provide these publications as a means of

furthering your professional development and

enhancing your knowledge of this industry. .

Councillors have done a lot of work on the issue

of glueboards; by supporting their continued use

in the industry as a tool of last resort. The

outcome of the review of the ongoing use of

glueboards is about to be released. PMANZ

awaits the outcome with interest

The use of Dichlorvos is also under review, and

submissions can be made directly to EPA.

We have received some positive news about the

new training course to replace the UPM

certificate. The new course run will by Rapid

Solutions starting in September 2014. Rapid

Solutions have been working closely with the

industry ITO, Careerforce, to get the training up

to the standard required. We have a number of

‘trainee’ members who have joined in the last few

months who have been waiting to enrol in this

course. Once they have completed the course,

these members will be able to call themselves full

members of PMANZ.

Be Safe Out there, see you all soon.

PMANZ Editorial Policy

Any organization that has a lot of members across a broad

area, whether it's a business, club or non-profit

organisation such as ours, benefits from publishing a

newsletter to keep lines of communication open between

members.

We publish this small newsletter for our members as a way of keeping them informed about industry issues that are

deemed to be newsworthy and of interest to members. At just a few pages in length, our newsletter is a miniaturized

version of a newspaper, and is constantly evolving as the association grows.

This editor sources available material, both locally and globally commensurate with our seasonal pests and topical

stories at that time, and occasionally compiles a story, or reports on a conference or meeting, as done recently after

the Glue Board Update in April this year, or as we did with the special Conference Edition, after the 2013

Conference and AGM.

It is only recently that we have started to incorporate advertising into the newsletter after a request from our

associate members, for which we are grateful, as it exposes our members to new products and reminds them about

existing products available to deal with different pests.

However, we would like to remind everyone; the PMANZ council does not, and will not endorse any individual

company, brand or product(s). The information and adverts contained in this newsletter is for member information

only and does not necessarily reflect the official views or opinions of the PMANZ Council and/or its members.

PMANZ would like to believe our readers are discerning and are able make informed decisions, drawing their own

Fishermen are not the only ones to exaggerate?

Mike Merchant, PhD, entomology specialist for Texas AgriLife

Extension.

I can tell you that fishermen aren't the only ones to exaggerate

when it comes to biggest-catch stories. I've heard lots of tales.

"I swear that cockroach that flew at me was 6 inches long!"

"That rattlesnake was as big as my leg!" And, maybe most

impressive, "The rats in our neighbourhood are as big as

cats!"

Nearly everyone and their brother have got a story about the

biggest rat. "Moby rats" they might be called. Or "super

rats".

A picture of one big roof rat sent recently by one our Texas

school districts got me thinking. What is a really big rat? And

what would it take to impress someone like Dr Bobby Corrigan

who has worked most of his life with rats? He is a rat expert

who consults on rodent control for New York City.

I decided I would send the school picture to Bobby and see

what he thought. He did not disappoint. In his methodical

way, he analysed the image, and shot back a series of

questions:

"Is that a scrotal sack under the tail, or possibly enlarged female genitalia? Hmmm...don't see any teats

"Was the tail long enough to be pulled back over and beyond the head?" [roof rat tails are generally longer

than the body... otherwise it would be a Norway rat.]

"How long was it dead?" "If it was dead for a few days in a ceiling," he explained, "...the body begins to

decompose, the skin gets stretchy when held by the tail, and they can appear much larger than what they

really are. Also, the body gases inside will begin to bloat the cavity and the whole end result is a very large-

appearing rat." [Never thought of that!]

Last but not least, he asked, "How much did it weigh?" [It takes more than a picture... you got to have real

data to impress a rat expert.]

Page 4: WHAT’S BUZZING?...Mike Merchant, PhD, entomology specialist for Texas AgriLife Extension. I can tell you that fishermen aren't the only ones to exaggerate when it comes to biggest-catch

4

Of course the upshot of all this was that I felt a little sheepish. I should have thought to ask those questions before I

even sent the picture. Duh! And who knew that you could rig a big rat competition by letting ‘Fatty’ stew in his own

juices a few days?

My last question to Bobby was, "What would it take to impress you? What's a really big rat?" He answered quickly.

"Any rat 2 pounds (907g) or over, but it has to be fresh," he added.

According to Bobby, the heaviest live Rattus norvegicus on record is 1.8 lbs (29 oz) or about 820g. Most “big boys”

weigh in the 775 g range, he said. And according to his book on rodent control wild Norway rats over the years have

been measured up to 19 inches or about 48cm.

By the way, compare these stats to what might be the biggest cat weighing in at 39 pounds (+17kg). And an average

healthy cat, I'm told, runs 8-12 pounds (3.5 – 4.5kg). No contest between rats and cats there. The chances of seeing

a rat as big as a full grown cat are nil.

Of course Dr Corrigan couldn't leave things gentlemanly. He had to add, "Texans claims that everything is bigger in

Texas. You guys should own up to the bragging."

Editor’s Note: For those of you who aren’t familiar with Bobby’s background, he is the Director of RMC Pest

Management Consulting, Richmond, Indiana. He has published over 150 technical publications in pest control and is

a regular contributor and columnist for Pest Control Technology and Pest Management Professional. Dr Corrigan is

the author of Rodent Pest Management: A Practical Guide for Pest Management Professionals; the Mallis Handbook

of Pest Control on rodents; and co-author of The Scientific Guide to Pest Control Operations. In 2008, Bobby was

inducted into the Pest Management Hall of Fame.

New Zealand News

PMANZ embark on advertising campaign for balance of 2014.

The association has inserted the first of three adverts into the NZ House and Garden and Air New Zealand

magazine ‘Kia Ora’ from August (winter). The campaign is costing the association $30,000. The first was an advert

depicting a mouse as shown on the left.

A second and third will appear in the same magazines in October (spring) and again in December (summer) with

different pests appearing.

The advert calls for customers to contact PMANZ on its Freephone number to get a professional Pest Manager

rather than a pest controller. PMANZ secretariat is logging these calls so that we can monitor the success of the

advertising campaign. Expect a call soon…

Wallaby concerns in South Island

More publicity about the damage wallabies can

cause, similar to that of a ‘’gigantic rabbit’’, has

been called for after confirmed sightings of the

pests. They can stop native bush regenerating,

can spread tuberculosis and also compete with

livestock for dry matter and green feed crops.

After the confirmed sightings of the pests by a

pest contractor, the Otago Regional Council

inspected the area and found wallaby droppings

in seven places in recently harvested forestry

blocks. Under the council’s pest management

strategy landowners are required to eradicate

any wallabies on their properties. Council policy

planning and resource management Fraser

McRae said the pest management strategy was being reviewed with a view to having a South Island-wide pest

management strategy.

Keep Calm and Retain the Business

Every pest controller faces the challenge of securing new business, but the time needed to win new clients can put existing contracts at risk. Jeff Callaghan, BPCA Consultant and lecturer on the BPCA training course ‘How to sell in pest control’, analyses the processes that need to be put in place to safeguard and retain contracts.

The battle to win new work keeps

getting harder as prices are driven

down by competitors, and expenses

are going up due to additional

bureaucracy, leaving many smaller

pest control companies struggling to

win new business and in some

cases fighting to stay afloat. For this

reason the retention of existing

contracts has never been so

important. It costs around 50 per

cent more to gain a new customer

than it does to retain one, so

retention should be at the top of

every company’s agenda. The

processes that are required for

retention should also be honed to a

fine art. As the existing holder of the

contract, you already have the upper hand; however, the crucial part is, knowing how to use that to your advantage

to give your customer no reason to look elsewhere.

Taking things for granted

It’s easy to think that retaining business is simply down to a matter of treating the customer courteously and

providing a good service. Yet, with clients constantly looking for more efficiency and cheaper prices it’s not so

straightforward. When contracts are up for renewal, the same care and attention that was paid at the initial tender

proposal stage should be carried forth as if the contract were brand new to a company. Becoming overfamiliar and

taking things for granted is an easy trap to fall into, and can be the catalyst for the breakup of many relationships.

When a contract goes up for renewal, you can’t afford to take a back seat and rest on your laurels. When attempting

to sell your services, it’s very easy to fall into the trap of ‘promising the world’ for a cheaper price (effectively

undercutting yourself). Also you should never forget your “frontline” process, and exactly what you need to do onsite

to ensure you make the profit you deserve.

Using your home advantage

It’s essential to treat the retendering process as if it were for a brand new contract. However, you have to remember

the distinct advantage you have as the incumbent contractor, knowing the contract inside out. Just as a football team

playing at home knows the dressing room, the feel and size of the pitch, and more importantly has the support of its

home fans, a contractor knows their clients’ buildings inside out, they have a feel for what is required across the

environment and they also have the support of the client and the individual users of a building. In the same way, a

football team intuitively knows how to use the home ground to their advantage to win, a contractor should be using

their own advantages to overcome competitors and retain the client. Existing contractors can also be more effective

in providing further efficiencies during retender, as they have already accounted for mobilisation and implementation

costs when the contract was originally won. For many businesses, it’s a struggle to provide cost efficiencies for new

contracts while accounting for equipment, staff and a raft of other elements that all affect the cost of contract

delivery. An existing service provider already has these elements and systems in place, so from the offset they have

the ability to transfer these savings over to the customer to offer them a better service at a similar or even

sometimes lower rate, something a new contractor coming in to tender will no doubt struggle to offer. It’s almost like

building up ‘no claims bonuses’ with an insurance provider.

Page 7: WHAT’S BUZZING?...Mike Merchant, PhD, entomology specialist for Texas AgriLife Extension. I can tell you that fishermen aren't the only ones to exaggerate when it comes to biggest-catch

7

Assessing customer needs

It’s simply not enough to deliver good service; yet, the best

way to garner the information needed to be successful in

retendering is to offer the highest standards of service and to

constantly assess how more can be achieved. By holding

regular review meetings, customer satisfaction surveys and re-

training where required, you can continuously keep on top of

what your customer desires. At the end of the day, if you don’t

sit down and ask exactly what your customer wants and how

you can make things better, you’ll be none the wiser when it

comes to including this information in the retendering

documentation.

Engaging with customers on a regular basis to communicate

needs and issues forms the very heart of the contract. As soon

as a new contract is won, the successful contractor should be

thinking about the retendering process from the very day the

work begins. By setting out to fully understand the contract and

how to better it throughout its lifecycle, pest controllers and

surveyors can be on their toes and ready to come out on top of

competitors when the client does finally look to retender. Complacency is a deadly sin!

Building a trusting relationship

There’s absolutely no point in going for a contract renewal on a site if it is

poorly managed and lacks the desired performance. Just simply looking

after your customers in the right way leaves you with far less to prove

when it comes to applying at retender stage. By opening up a dialogue

and getting to know your customers as people, you can begin to build a

trusting relationship and bond which will have a great effect on whether

contract retention is successful. Truly knowing your customers also

means that you will have a lot more critical information at your disposal. If

after three years managing a contract you know that the customer has a

strong stance on corporate social responsibility, then make a song and

dance about it in the proposal. You may learn that a customer is keen to

drive towards a greener approach to business, so make sure that this

forms an important part of your pest control proposals. Clients may not be

requesting this information but, if you know it’s what the customer wants,

then you have a large advantage over those trying to win the new business.

The devil’s in the detail

The advantages for an existing contractor during the retendering stage are vast, but it’s imperative to remember that

this isn’t a time to rest on your laurels. It’s easy to think that simply having a great relationship with a client will lead

to a retender win; however, these relationships need to be acted

upon and put to good use to provide a better service at a competitive

price. Having a healthy relationship is great, but a client in this

current economic climate might overlook this in favour of saving

themselves some money. Use every detail gathered over the

lifecycle of a contract, be it of little or great importance, to its full

effect to make sure your tender document sits a cut above the rest.

Little things that may seem insignificant at the time could in fact be

the details that place you above competitors, so it’s imperative to

avoid overlooking the smallest of things. If you truly know your

customer; you’ll know how to retain their custom.

Extreme IPM for Food Plants

By The Sprague Pest Experts

27 June 2014

At this year’s Sprague Food Safety Pest Management Conference, the Sprague Pest Experts and some the

nation’s leading food safety and pest management authorities shared the latest information on food safety

and pest management trends and practices.

One of the sessions focused on Integrated Pest Management practices and how, when designed and deployed

correctly, IPM can deliver and exceed the desired results. Sprague Pest Solution’s Technical Director, Jeff Weier,

broke down the company’s approach to IPM in food processing and distribution facilities.

Weier encouraged pest professionals to use the numerous control options at their disposal. “Technology should

serve us and support what we need it to do,” Weier said, emphasizing technology’s vital role in delivering a fully-

integrated IPM program.

The philosophy behind Sprague’s “extreme” IPM program follows these principles:

Use technology to your advantage

Be pro-active rather than reactive

Chemical solutions are temporary solutions

Always seek permanent rather than temporary solutions

Exclude the pests first

Use selective solutions

As regulatory scrutiny increases and third-party audits become more demanding and invasive, QA managers need

to consider a more evolved version of IPM with their pest management partner or in-house staff. This new advanced

program should focus on:

Inspection

Trend analysis

Identification

Risk assessment

Page 10: WHAT’S BUZZING?...Mike Merchant, PhD, entomology specialist for Texas AgriLife Extension. I can tell you that fishermen aren't the only ones to exaggerate when it comes to biggest-catch

10

Identifying vulnerable areas

Developing and implementing an action/response plan (thresholds)

Evaluation of results and modification of the risk assessment and action plan if goals are not met as

part of the validation process

“Our IPM philosophy is to identify those prevention and elimination methods that, as much as possible, impact the

target pest, effectively eliminate it but affect nothing else,” said Weier.

Weier talked about the “stacking effect” of treatment options when designing and executing a pest management

program in a food processing facility. The pieces of the “stacking effect” puzzle include:

Fumigation

Targeted insecticide applications

A comprehensive inspection of incoming shipments for signs of pest activity

Exclusion

Trapping

Solid, consistently applied sanitation protocols

On every service visit, Weier and Sprague’s service technicians focus on achieving a permanent solution to the

client’s pest problem. They practices are outlined below.

Make no routine or general surface applications

Preventative applications are generally not justified

Choose the proper formulation and application technique

Identify and remove the source of the infestation and the conditions that allow pests to survive

Choose products and application methods that are effective and low risk (least toxic)

Strive to reduce waste

Give preference to materials and applications that are target-specific.

Post-treatment evaluation and validation are an equally important part of the IPM process. Reviewing which

elements of the plan are working and what needs to be adjusted is critical.

“Verification of a control program means we are doing what we said we would, but validation means the program is

meeting the needs of the client – and that is what we are aiming for,” said Weier.

Mosquitoes “Smell” and “Taste” DEET and other Repellents

August 6, 2014 by Entomology Today

Mosquitoes not only have a sense

of smell for certain insect

repellents, but they also have a

sense of taste for these chemicals,

according to scientists at the U.S.

Department of Agriculture (USDA).

Joseph Dickens, an entomologist

with the USDA’s Agricultural

Research Service, discovered for

the first time that a taste receptor

located on a mouthpart of

mosquitoes is sensitive to DEET, the most common active ingredient in insect repellents.

Scientists have known for some time that DEET works by interacting with the mosquito’s smell (olfactory) receptor

cells, causing the insect to become confused and to fly away. Dickens’ findings, published

inNaturwissenschaften, demonstrate that DEET also interacts with a specific mosquito taste (gustatory) receptor,

which could indicate the existence of a sensory pathway for taste that deters blood feeding by the insects.

Sensory hairs at the tip of the proboscis of the yellowfever

mosquito have cells that respond to a feeding deterrent and the

mosquito repellent DEET. Photo by Joseph Dickens and Gary

Bauchan.

Dickens and his colleagues recorded responses of yellowfever

mosquitoes (Aedes aegypti) to six different chemicals. They

tested a feeding deterrent, quinine, and various insect repellents,

including DEET, citronellal, picaridin, and IR3535.

The experiments involved pinpointing the pair of

tiny flaps located at the tip of the mosquito’s

proboscis or “beak.” These flaps, which have tiny

hairs that serve as chemical sensing organs,

make contact with a human’s skin. Electrodes

were placed on a single hair to record the

electrical impulses from nerve cells within the

hair.

Scientists discovered that three sensory cells

were activated in the hair. One cell was activated

by salt, a second cell was activated by sugar,

and a third cell was activated by either quinine or

the insect repellents tested, including DEET.

Mosquitoes can sometimes transmit pathogens

that cause harmful diseases like malaria, yellow

fever, and West Nile virus. Learning more about

their sense of taste and smell could help

scientists develop better protection methods and

management techniques for mosquitoes, other

insects, and arthropods.

Technical Hints

Preventing and Eliminating Odours from Dead Rodents (and Other Animals)

The Smell of Death

Ooooh that smell

Can't you smell that smell

Ooooh that smell

The smell of death surrounds you

—From "That Smell" by Lynyrd Skynyrd

Scientifically, it's a combination of sulphur dioxide, methane, benzene

derivatives and long chain hydrocarbons produced as various body

parts decompose. But to those familiar with the stench of dead bodies,

it's simply the smell of death. Like all smells, it is hard to describe. But

unless you're a real vulture, you'll find the smell disgusting and

sickening.

Perhaps there is an evolutionary reason for our gut-wrenching reaction to the smell of death. We're repelled by the

bloated corpse, and it's a good idea: its flesh harbours disease, it can sicken and kill. By avoiding rotting animal

carcasses your ancestors lived long enough to pass on their genes!

The smell of death can be a major customer relations problem in pest

control. You've gotten rid of the pests; say a group of rats, but the

resultant smell may make your customer think that the solution is

worse than the problem.

Dead animals will smell until they are completely decomposed or until

they are dried out. The damper the site, the longer the odour will last.

If a rat dies near a steam pipe, the smell can be horrible for weeks.

The odour from a dead mouse may last only a day. In fact, there may

be no noticeable odour from a single dead mouse, but several dead

mice in the same area could be a problem. A dead rat may smell

really bad for a week, but there can be some lingering odour for as

long as a month.

The obvious solution is to find and remove the dead animal or

animals, and then ventilate the site. But a better solution is prevention. In residences, offices or other sites where

odours from dead animals are a concern, use pest-proofing and other IPM tactics to prevent pests from entering the

structure. If there are rodents inside, use a control method that holds the animal rather than one that allows it to

wander off and die in inaccessible areas. Use traps rather than baits so that you can dispose of the carcass. Check

traps and glue boards often to remove dead animals.

Accumulations of dead insects can also cause an odour problem. For example,

Dead insects can rot in an insect light trap (ILT) catch tray. Be sure to empty and clean them frequently.

An insecticide-treated bee nest in a wall void can become quite stinky as the dead bees and the brood rot

and as the honey deteriorates.

There are several ways to get rid of odour problems in a building.

You can take the odour out of the air by using an air cleaner with an absorbent filter.

You can add something to the air that neutralizes the odour.

Or you can add a new, more desirable odour that temporarily masks or covers up the bad odour.

Air cleaners usually use a replaceable absorbent filter such as activated charcoal or silica gel. When room air

circulates through the filter, it absorbs and removes particles.

Odour neutralizers often contain bacteria or enzymes that break down the organic compounds that are causing the

odour. Others use ionic minerals to neutralize odours. Some odour neutralizers also contain an artificial fragrance,

but many do not. Odour neutralizers are available as powders, granules, sprays, or as rods.

Masking deodorants are highly concentrated fragrances that simply cover up the bad smell. They don't neutralize it.

They can be applied as granules, aerosols, mist sprays, or released through a cotton wick. Since they have a very

strong fragrance, use them carefully to be sure they aren't more offensive than the original odour.

Finding the Source of the Smell

To locate a dead animal in a wall void, use your nose. Flies in the room may lead you right to the spot (some

technicians have been known to release flies to find a carcass). You may see maggots migrating away from the

carcass. Or, with a larger animal, you might find a damp

spot or a stain on the wall or ceiling.

The best solution is to remove the carcass. But if you

think you've found the dead animal and it can't be

removed, drill a hole through the wall one foot above the

floor and pour or inject a disinfectant, odour neutralizer,

or masking solution. Do the same for the voids on either

side. Using a multidirectional spray tip will give you

better coverage inside the void. Be sure to plug the

injection holes afterwards. If you can, seal off any cracks

that are allowing the odour to escape from the void.

Then, use a fan to draw fresh air into the treated area,

forcing the old air out. Place the fan to blow air out of the

window or vent that it is placed in and to draw in fresh air

from another window or vent across the room.

If you cannot locate the carcass or carcasses, you will

have to apply a neutralizing or masking agent to the

general area. Use a misting or ULV machine to treat the

entire room. You will need to repeat the application until

the carcasses are dry.

You also may need to treat for blow flies, dermestid

beetles or other pests that infest decaying carcasses.
