These spider's seem to be every where. In the year and a half that me and my wife have lived in the home we have found or killed over 200. Not that I'm actually keeping count but it seems every day I go into the basement there is a new one laying somewhere. I have also killed many in our yard while mowing. They are becoming rather large and I can see them going over twigs and see the grass moving as I mow. I bought a product at Walmart last summer and it seemed to help, I sprayed around the baseboards and the spiders didn't make it 4 inchs away before they were dead. But I can't seem to stop them from getting into my house. Will onslaught help or what product do I need?
Generally speaking, Onslaught will kill wolf spiders, but it does not offer a fast knockdown. Onslaught is micro-encapsulated and can take several hours to kill the spiders. We usually recommend Cyper WP because it offers a faster knockdown and the same residual as Onslaught and it can be used for indoor and outdoor spider control. The active ingredient in Cyper WP is cypermethrin, which is known to be one of the top choices for spider control. Spraying Cyper WP will also help to get rid of the insects that spiders feed on and that will help to stop new spiders from moving in. Indoors, spray around all baseboards, door frames, window frames, under appliances, in closets and storage rooms and in areas where utilities (cables, pipes, wires) enter into the structure. Outdoors you should spray around the bottom of the foundation, on the ground adjacent to the foundation, door frames, window frames and places where the utilities enter into the structure and any other place insects can harbor. We have included Cyper WP in our spider control kit, which also contains glue boards to help monitor the infestation (and help catch the spiders too).
