I'm good Cap. The kid and I got most of the dead tree cut up except for the biggest part of the trunk. Hubs will get the big chainsaw and take care of that tomorrow, then we'll take the wood up to my dad. He's running out! Ate too much for dinner. Too yummy.
It was confusing me. I have the same thing called Permectrin ll, says it's an animal and premises spray and the label gives dilutions for both. When I looked up what granny got, both places I looked only gave dilutions for premises and said don't use on the animal. I must have looked up the wrong thing somehow.
