Hi-Yield 38-Plus Insect Control 38% Permethrin is not labeled to be used on anything edible and would not be recommended for that type of application. Bonide Eight Insect Control Vegetable, Fruit and Flower is labeled for use on fruit and it contains the same active ingredient.
Hi-Yield 38-Plus Insect Control 38% Permethrin should be applied as directed on the label and dried 24 hours prior to rainfall for the most effective control.
Per manufacturing label it is recommend to discard mixed solution of Hi-Yield 38-Plus Insect Control 38% Permethrin within 24 hours.
Hi Yield 38 Plus is a good product, however, it is not labeled for spiders.
We would recommend a product called Onslaught FastCap Spider and Scorpion Insecticide. It is labeled for mosquitoes, spiders and ants. This would be an excellent product to use in your backyard. It can also be used inside as well as a crack and crevice spray if needed. It has a quick knockdown as well as a residual of 30 days.
We do carry Tick Block which contains permethrin that can be used to treat clothing only.
