I found a couple flying "swarmers" in my basement. I've lived there for 12 years and this is the 1st sign I've seen. My buddy is an exterminator and he recommends a system they offer that is $350 up front then $35 a month with a 2 yr contract. He says its as strong on day 1 as it is 2 yrs in. Seems a little high. I've looked everywhere and can't find the hive or any of the dirt tubes. Anyone have any experience with the little bastards?
