I live in Michigan and have a problem with spider webs, on a daily basis. They are all over the decking, underneath, on my black metal balusters(posts), etc.
What is the best product to spray and how long will it last?
As you will learn in our SPIDER CONTROL ARTICLE, the best way to beat this pest and their webs is to treat all the areas they like to nest. The best product for this job is the DELTAMETHRIN. Long lasting and repellent to spiders, it will both kill what’s living on your home and prevent new ones from coming around. We recommend doing a good web removal cleanup first using one of our SPIDER WEB REMOVERS first. This will allow you to treat the open areas thoroughly without obstructions.
When spraying, be sure to get up under decking as best as possible, They also like to live in the corners of the home, up under eaves and soffits and around doorways and windows. A light treating in these key areas will go a long way.
