Pesticides and Tick Control A Word About Pesticides

Acaracides are insecticides or pesticides used for tick and mite control

Pesticides can be harmful The toxic impact affects life species

differentlyInsecticides can provide 85-90% or

better tick control

Biologically-based pesticides, (i.e. pheromones, microbial pesticides)

Pyrethrins and Other Natural Insecticides

Synthetic insecticides

Pesticides and Tick Control Types of Pesticides

Page 68: Tick-borne Diseases in Connecticut

All pesticides must be registered with federal and state environmental protection programs

The decision to use pesticides on your property is up to you.

Pesticides and Tick Control Pesticide Controls

Page 69: Tick-borne Diseases in Connecticut

Selecting a Tick Control Service

Select 3 services that are registered with the Department of Environmental Protection

Ask DEP for any violations filed against the business

Get a written estimate, understand what the job entails

Contact the BBB

Page 70: Tick-borne Diseases in Connecticut

Selecting a Tick Control Service

Ask the business for a certificate of liability insurance

Ask to see the license of the employees spraying for ticks

Ask for references

Page 71: Tick-borne Diseases in Connecticut

Questions to Ask the Applicator

Will signs be posted around the property after application?

Will the equipment used be safe and up-to-date?

Will a written pest control plan be provided?

http://www.gemplers.com/safety/labels/lawnturf/CT5X5PK.html

Page 72: Tick-borne Diseases in Connecticut

Questions to Ask the Applicator

Will the plan state exactly what pesticides will be used

Will information be supplied about various non-chemical landscaping techniques

Page 73: Tick-borne Diseases in Connecticut

When Should Pesticides Be Applied

To protect against ticks, spraying in the Spring will control larvae and nymphs

An application in October will control the adult ticks

S. Perlotto

Page 74: Tick-borne Diseases in Connecticut

Where Should Pesticides Be Applied

Spray the perimeter of the areas that are most used by the family; garden, playscapes, picnic table.
