How do you kill borer bees?

Answer by  ashanna (12)

You could try using almond oil, spraying around the infested area. This can help deter them from returning. I would then suggest sealing any holes with some elmers glue, borer bees will return to the same hole every year so it is important to block and seal any holes. You should be able to order these products from online catalogues.

You should do this in the evening after the bees return to their home. Use an insecticide designated for these insects. Spray into entrance of the nest. Repeat the next evening. You can fill entrance area with putty or filler and finish. Spray non toxic insecticide around areas they frequent.

If you have a current problem with these bees you will need to dust a residual dust in all of the new openings.

You should use products containing Cypermethrin. Adults are easy to kill, but larva takes six to twelve months to emerge so you must use the product again after few months.
