We had a bee removal person come to our house about two weeks ago. He removed some bees from the exterior wall of our house. He left with a big bucket of bees, so I assume he got the queen. He said there would be straggler bees, and he would come to pick them up if we called. There are still at least 30 - 50 buzzing around in the area where the nest was removed. Unfortunately he is not returning our requests for additional help. Is it possible for the leftover bees to last this long? Not sure if he didnt do a complete job or if new bees moved in. Do you suggest I have someone else come in or wait a bit more.
