Without bees we wouldn’t have crops or plants, but they can become a nuisance if they choose to inhabit your home.
They typically swarm in the spring, which is when they go in search of new places to build nests. They don’t seek human habitations intentionally, but the structures are abundant and sometimes they don’t see other choices.
Many of the bees in our area are very docile, but certain colonies can grow aggressive. When that happens, they’ll swarm and sting anything that invades their space. This encounter wouldn’t be pleasant for anybody, but could turn deadly for anyone who is allergic to bee stings. Even those who have never had an allergic reaction in the past could need emergency care after suffering from massive bee stings.
Worse, they attract other pests. They’re happy to fill every void with honey, which means rats and roaches will be right behind them.
Never try to remove a colony on your own. Doing it safely requires training and the proper equipment.
