First I would go outside and see if see any bees or wasp go outside and see if you see any bees or wasp flying because they have to forage. If there are honeybees I would call a beekeeper or someone that has done bee removal before. also you would probably would hear consistent buzzing unless you make a loud noise that would cause them to buzz. Happy Beekeeping! -Alex

I'd check it out ASAP in case you have a short in your house wiring somewhere. But, if you poke a little hole in the wall and a bee comes out, it's probably bees.
