Finding the best spider control products depends to some extent on what part of the country you're in and what spiders you happen to be dealing with. Spiders setting up camp in large numbers inside your home likely have different behavioral tendencies than web-weavers outside the home, and control efforts should be adjusted accordingly. Which products or treatment approaches work well for some spider species may not work well for others. That said, many of our most recommended spider control products work well against many types of spiders in various environments.
Professor Pest's Spider Tips:
Before beginning any spider control treatment, be sure to identify the type(s) of spiders you're dealing with. Consider the underlying reasons why these particular spiders have chosen to establish themselves in this particular area. In some instances, habitat modification or other subtle changes around your property might make the environment much less attractive, removing the need for chemical spider intervention.
