A fraction of a degree?
Not buying it.
Ticks are a serious issue here in southern NH. I personally spray my yard/grass at least twice a year now. I tried cedar oil last year because it is supposed to be non toxic to the good insects like bees.
I used to spray permetherin. I still spray that on my boots and my yard work jeans. Sawyer makes a diluted version you can buy at Walmart.
Last year I bought another insecticide that I purchased from an online supply house. There are actually three different insecticides I mix together in my 4 gallon backpack pump sprayer. After spraying this there were no ticks or mosquitos for about a month. I also treat my birdbath and the little pool week keep in the dog yard for the beagles.
FYI, I do all the things in the previous post because I know multiple people who now have Lyme Disease from a tick bite.
