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.
You want to keep the product at least 5-10 feet outside the drip line of anything edible when treating with Hi-Yield 38 Plus Insect Control. We do offer products that can be applied to fruit trees for boring insects. Please click on the link below for those products. Please refer to the product label for specific application instructions. Please let us know if you have any questions.
