We target Spiders during our regular service trips but due to their nature and habits we do not include them in our warranty.  Unfortunately most of the chemicals we use don’t control spiders all that well for many reasons.  However our chemicals do work well on many of the insects that Spiders feed on.  The idea here is to reduce their food source which in turn makes the environment less attractive to them.  While chemical application has a place in spider control it is just one step of many to reduce the likelihood of Spiders in the home.  Some other factors to consider are exterior lighting, reducing clutter indoors and out, and managing exterior lights to attract less flying insects that Spiders feed on.
