Home Remedies to Get Rid of Carpenter Bees

Do-It-Yourself Solutions and Traps

Natural Citrus Spray

Carpenter bees hate the acrid smell of citrus fruits and this is a simple way to get rid of them.

  • Peel citrus fruits and boil the rinds in water
  • Get a  spray bottle and fill it with the citrus-extract water
  • Spray the carpenter bee burrows and be wary of the female carpenter bee sting.

Almond Oil

Almond oil, like most other essential oils, is a natural insect repellent. If you have noticed any carpenter bees, holes or tunnels, use cotton wool or a soft cloth to apply almond oil around the affected areas. This repels the pests from burrowing further around the wood surface.

Plug Up the Entrances

One of the easiest ways to disrupt carpenter bee infestation is by plugging their nests using wood putty, corks, dusted plugs, copper gauges, and other such materials. This might discourage the bees from nesting on the wood though they can still burrow their way out.

Replace All Wooden Materials

If you have noticed many holes and tunnels on wood surfaces, replacing the affected parts is a great tactic. This ensures there are no larvae hidden inside these nests. Make sure the new wood you use is treated and painted to discourage further damage by carpenter bees.


What Kind Of Spray Will Help?

Citrus spray is one of the most effective sprays to get rid of carpenter bees. Most insects have a natural aversion for citrus spray. You can easily prepare this spray by cutting rinds of citrus fruits and boiling them in a little water. Use a spray bottle to reach inside the holes and also apply to the unaffected surface of the wood.
