I realize this may be somewhat off topic, but I can't find another group that would handle this type of issue on usenet. I've also googled extensively, but haven't found anything worthwile (other than beehive removal, which I don't think applies here). So I hope it's OK to post this here. I hope to PREVENT any extensive home repairs at any rate. ;)
I live in a concrete block building in Florida. In the past few days, I've heard a buzzing sound about twice a day inside the one outside wall. I only hear it at about 8:30 a.m. and again at about 2 p.m. Other than that things are quiet. I've already called in a bug expert who specializes in bees and such. He seems to think it's a solitary wasp that is getting in somewhere, but he couldn't seen where it may be entering the house.
I have spent some time outside monitoring the area and haven't seen any activity. He suggested that he could "dust" the area, but that it wasn't really worth him charging me for it (he checked the problem out for free, but would have to charge a service call if he did anything -- he was very nice about this, but not nice enough to tell me what I could do myself ;)). This leads me to my question: What can be done here? Is there a particular product that I could dust the general area with myself? Should I drill a hole in the wall and spray or dust inside it? (I can't pinpoint the exact location between the studs though, so it may require several holes) Or is there a kind of bait that would work and also serve to destroy any potential nest? If so, where would I best place it?
Since I can hear the buzzing sound quite clearly, I assume that the insect is between the concrete block and the drywall. And since I only hear it for short periods of time, but on a semi-regular basis, I assume that it is indeed a solitary insect (at least so far). Of course there was no buzzing when the bug guy was here, so he never did hear it.
Any help would be greatly appreciated! KB
