Oftentimes people attempt to spray them with insecticide hoping they will go away. This can often make the problem worse. Sometimes, the colony will push deeper into the structure, or if they die, the abandoned honey and comb attracts other pests like roaches, hive beetles, wax moth and rodents. Also, new colonies swarming in the area are attracted to the scent of remnants of the old hive. It is important to remove as much of the nest as possible (wax and comb) and to seal up their entrance to ensure future colonies will not come back to the same location. If a structure has ever had a bee infestation, there is a higher chance the scent of the old hive will attract new scout bees looking to relocate their colony. You need to seek the help of bee exterminator Amherst NY to remove the bees from your home.
