We had a HUGE wolf spider problem. Mostly located in the basement and an old beat up porch, but we could see up to 20 of them on a nightly basis, and our glue traps were constantly catching them. Within 6 weeks of treating we were down to a few (that's with a visit every 2 weeks for those 6 weeks). Within 3 months they seemed to be gone, for the most part. Once the spiders were under control, we have been maintaining well with a quarterly visit. As a bonus, I no longer have centipedes down there too. This past visit Brian even took care of a large bee's nest that sprang up suddenly on the side of my house. I wasn't expecting that, so that was nice. My only complaint is the phone system they use seems to have issues; sometimes I receive incorrect automated calls telling me to schedule a treatment that is already scheduled. I also wish they sent a reminder email or call to let me know when the quarterly service is due, because I really don't want to get behind on treatments...when I was late on time, the spiders were ready to descend.
