We currently have a variety of spiders making a mess on the outside of our home-webs and spider poop. Should I clean the house before I spray for spiders or after I have applied your product? Thanks!
It is recommended to perform powerwashing prior to the application of Bifen IT. Washing after could interfere with the residual of the product.
