If a property owner suspects that a honey bee colony has entered a structure, they should attempt to confirm the insects are indeed honey bees. Other possible insects that might invade the walls of a structure are carpenter bees, yellow jackets, or hornets. Honey bees vary in color from yellow to black, have a black or brown bands across the abdomen. Honey bees are about 2/3 of an inch long and the body is covered with setae or hair. The foraging honey bee will have baskets on each hind leg which will be often loaded with a ball of yellow, orange, red, or dark green pollen.

Bees can be a nuisance for you or your family and can be removed. This is called a "cut-out". Why would you want to remove a colony from a wall or other structure? Once the bees have set-up housekeeping for more than a few days, the job of removal often becomes more difficult. Sometimes much comb (beeswax), brood, and honey are stored in the wall of a structure. Simple injecting a pesticide in the wall to kill the bees and leaving the comb there is risky. The comb will attract ants and other insects and may ooze through the wall or ceiling when it melts during hot weather, causing extensive damage.
A "cut-out" may be your best and lowest cost option, and the bees often can be saved.
