Permethrin Facts
2,250 times more toxic to ticks than humans
EPA: Reasonable certainty that permethrin-treated clothing poses no harm to infants or children…27 X below LOC
Low skin absorption…metabolized quickly
Exposure data also studied by National Research Council…Committee on Toxicology Conclusion: Adverse effects unlikely
Also used for scabies and head lice control
Phase 2 Game Plan - Protect Your Yard
Wildlife and habitat management
Perimeter sprays effective …NOT the entire yard
EcoExempt IC2
Botanical– Rosemary Oil 10%– Peppermint Oil 2%– Oil of Wintergreen– Vanillin
EcoExempt was as effective as bifenthrin, a synthetic pyrethroid insecticide
– Vector-Borne Disease Laboratory, Maine Medical Center Research Institute
Damminix Tubes
Damminix Tubes…however Several initial university studies
looked promising
Follow-up studies, NY & CT– Replicated, multi-year– No significant effect on tick
populations…not all tick-carrying
animals take cotton
Company website – testimonial driven, questionable trial data
Can Deer exclusion fencing reduce tick populations on a homeowners property???
Fact or Myth?
