Bees nest naturally in cavities, such as in hollow trees, old barrels and behind walls. Although bees do not damage the structure of the house, honey can stain walls at high temperatures. Bee stings can be fatal for people who are allergic to them. They can be killed with insecticides. If you see that there is no immediate threat from having the bees on your wall, wait until the end of winter or early spring to remove them because there will be fewer bees and less honey in the hive.
- Touch the wall where the bees are. Listen to the buzzing to find the exact location of the hive. You will have to apply the insecticide as close to the colony as possible, so seeing your site improves your chances of succeeding.
- Inspect the area around the hive to find holes 5/16 inches (0.79 centimeters) or larger. The bees use these holes to enter and leave the nest. If you can not see an entry hole, drill a 1/4 inch hole in the wall. You will need it to introduce the insecticide into the cavity.
- Wear a long-sleeved shirt, long pants and a hat to protect yourself because bees can fly out of the nest towards you.
- Spray an insecticide spray that is correctly labeled to kill bees, wasp, and hornets, directly at the entrance hole. Do this during the night, when adult bees are usually in the hive. You can find the spray in stores with gardening items.
- Open the wall if the bees have been inside for more than two or three weeks.
- Remove all wax, honey, and dirt from the nest because it could attract other bees, insect pests, and rodents. The extra syrup can also stain and damage the walls.
- Seal all the holes that lead to the cavity that was infested by the bees. The smell can attract new bees to make their nest inside.
