Hi, I have a wolf spider problem. 3000 sq ft 1960 split level. Please advise how to solve. They seem stronger than the Orthodox home defense. Thanks.
Wolf spiders are fast moving, predatory spiders that can cover a large area when feeding. For this reason it’s important to get the ground treated. Especially mulch areas. They like to live in pine straw, wood chips and even under cut grass that’s left lying in the yard. To keep their numbers down inside the home, it’s important to spray the foundation outside and apply granules to at least a 10 wide band around the home.
For spraying, go with the CYPERMETHRIN featured in our OUTSIDE SPIDER CONTROL reading. This active is both toxic to spider and repellent. They tend to avoid treated surfaces so it will keep them at bay where applied. But it will also kill any that are nesting in the area. Unfortunately it’s not the best at penetrating any ground nests that might be present nor does it last as long as a good granule.
For that you’ll need to apply some BIFEN. Designed to handle water well and soak into the ground, the Bifen should be applied all the way around the home every 2-3 months. But don’t be afraid to treat a larger area, like the entire yard, if you have reason to believe the spiders are living anywhere on your land.
Once under control, the Cypermethrin and Bifen should be applied every 2-3 months to keep things under control. And if you have activity inside, the Cypermethrin can be used there too.
