How to Get Rid of Roof Bees

Updated April 17, 2017

Bees are a welcome addition to most gardens. They play an important role in plant and flower germination and life cycles and are generally not aggressive toward humans unless provoked. Bees in the roof are another story altogether. A hive in this area of the home can attract other rodents and pests into the house. Additionally, roof bees can easily get into the general living area of the home and cause mischief. It's important to get rid of roof bees and then take measures to prevent their return.

  1. Find the spot where the bees have built a hive in the roof. It is easiest to do this at dawn, when the hive is awakening. Watch where the bees seem to come from until you have a general idea of their location.

  2. Climb up the ladder and use a flashlight to pinpoint the exact location of the bee's nest. It's safest to do this at dusk or at night. Mark the spot with orange caution tape so that you will be able to find it again quickly for treatment.

  3. Read the directions on the can of bee poison and follow them closely. There are several brands and most of them work as well as the next. Wear thick clothing and gloves when applying the poison. At dusk, when the bees are in their nest for the day, climb up the ladder and spray all of the poison into the crack where the bees have made their hive.

  4. Monitor the bee activity for several mornings after applying the poison. Depending on the size of the hive and the extent of the infestation, you should start to see an immediate decrease in bee activity. If bees are continuing to come and go from the area, repeat the poison treatment one more time.

  5. Caulk any cracks or holes in the roof or between the roof and the house. Bees often build hives around a crack in wood. Prevention is the best cure when it comes to keeping bees out of your house.

  6. Call a professional exterminator if the bees have been in the roof for longer than six months or if you cannot kill the hive after two rounds of poison spray. Sometimes an infestation is bad enough to need more extensive treatment.

  7. Tip

    Inspect your house for cracks and other easy entrances each fall. Seal with caulk each season.


    Bees will sometimes swarm when their hive is invaded, so proceed with extreme caution when applying the poison.
