When working with customers who have spider infestations or are starting to see spider activity in their homes, the environment surrounding their homes can be chock full of conducive conditions.

Lush vegetation, landscape lighting, and large trees (especially if they touch the structure) around a home, townhome or apartment complex are havens for spiders. They will seek any opportunity to build webs near outdoor lights while active hunters will search the grounds near a doorway or a window for a chance to snack on prey.

When dealing with spiders, keep in mind that prevention is key. It’s important to thoroughly inspect outside and inside a structure. Look for openings, gaps, damaged window screens and weather stripping. Also, inspect low –  under decking, windows sills and the underside of patio furniture; and high – under eaves and light fixtures. When selecting a pesticide, use a microencapsulated product like Fendona® CS Controlled Release Insecticide, which will provide longer protection. Keep in mind that by eliminating the spider’s food source, you can also reduce their population, so pay attention to other insects in the area and use broad spectrum insecticides.


After spending more time at home over the past year-and-a-half, customers may be your best sources for pinpointing where pests could be hiding and/or entering structures on their property. As the subject matter expert, you can provide useful tips to help them reduce the conducive conditions around their homes and yards, leading to pest-proof homes and satisfied customers.
