I frequently have a dozen, or so, gigantic yellow, furry, bumblebees (?) aimlessly flying under the eves of my house. Always on the east side. They seem harmless as they bump into each other and poop on the side of my house about a foot below the soffits. Are they harmless and what are they doing?
Actually they are carpenter bees. As our CARPENTER BEE CONTROL ARTICLE explains, they drill through wood to build nests. In these nests they stay all winter and every spring, they’ll emerge to mate and make new nests. The poop you see is from them and many times is actually the wood pulp they create when drilling though some excrement may be mixed in with it.
In our article you’ll learn the males fly around looking for females and this quest by them is never ending for a month or two. They don’t sting and for the most part are harmless. But females can sting and the damage they do can be significant. I suggest you start treating with the DRIONE DUST we have listed in our article if you want to stop this from happening as I expect it will get worse and worse each year with more returning and thus more damage being done until you stop them.
