If you decide to eradicate honeybees from a wall void, be prepared to pay for the services of an experienced beekeeper and a carpenter to repair the opening created during removal.

To permanently solve the problem, the entire nest and the bees must be removed and the entrance resealed. It is not enough to simply spray inside the nest entrance with an insecticide, because after the insecticide degrades the cavity and combs are attractive to future swarms of bees.

If bees in a wall are killed but the nest is not removed, the combs are no longer ventilated and wax and honey may melt and stain interior walls — the honey also attracts ants, cockroaches, mice, and rats.

An experienced beekeeper can expose the nest and remove the bees and comb. The property owner is responsible for hiring a carpenter to reseal the void. If you rent your residence, you will need approval from your landlord to remove bees.
