Sealing a Bee Hole in an Exterior Wall
- Jul 12, 2018 -

Carpenter bees are so-named because they build nests by boring holes in weathered, intact wood -- often the exterior walls and siding of homes and other structures. Carpenter bees can do extensive damage. This includes structural weakening, as holes extend deep into the wood, water damage from rainwater and other moisture penetrating the wall, and aesthetic damage from the unsightly appearance of the holes. Filling cracks and other defects before they're exploited by the bees, as well as permanently obstructing holes the bees have already drilled, is the best defense against wood damage by carpenter bees.


1

Treat active carpenter bee holes with an approved insecticide. Commercially available insecticides containing pyrethrum or carbaryl in either dust or liquid variety can be introduced into the bee holes after dark when bees are dormant or in early spring while they are still hibernating. Low-toxic dusts that contain boric acid are also effective against carpenter bees. Dessicant dusts such as diatomaceous earth that kill bees by drying out the body covering are safe around humans and pets.


2

Wait a few days after application of insecticide, stuff 0000-grade steel wool into each hole to permanently obstruct future use. Carpenter bees frequently re-use old holes after the insecticide has dissipated.


3

Cap the hole for painting or finishing by applying a plug of caulking (acrylic silicone/acrylic sealant/silicone/sealant/adhesive/potting sealant/potting adhesive/potting compound/UV glue/Silicone sealant/Potting silicone sealant/Huitian adhesive/Huitian silicone/Huitian sealant/flange sealant/conductive sealant/Electrical sealant/electronic adhesive/epoxy sealant/epoxy adhesive/PU adhesive/gasker maker/thread locker/Thread adhesive) or wood filler on top of the steel wool.


4

Fill any existing cracks or depressions that may serve as starting points for bees to bore holes with wood filler or silicone caulk (acrylic silicone/acrylic sealant/silicone/sealant/adhesive/potting sealant/potting adhesive/potting compound/UV glue/Silicone sealant/Potting silicone sealant/Huitian adhesive/Huitian silicone/Huitian sealant/flange sealant/conductive sealant/Electrical sealant/electronic adhesive/epoxy sealant/epoxy adhesive/PU adhesive/gasker maker/thread locker/Thread adhesive).


5

Maintain exterior wooden surfaces by painting or varnishing regularly to prevent the bare, weathered appearance known to attract carpenter bees.


Things You Will Need

  • Commercially available bee insecticide

  • 0000-grade steel wool

  • Exterior wood filler

  • Silicone exterior caulk (acrylic silicone/acrylic sealant/silicone/sealant/adhesive/potting sealant/potting adhesive/potting compound/UV glue/Silicone sealant/Potting silicone sealant/Huitian adhesive/Huitian silicone/Huitian sealant/flange sealant/conductive sealant/Electrical sealant/electronic adhesive/epoxy sealant/epoxy adhesive/PU adhesive/gasker maker/thread locker/Thread adhesive)

Tip

  • Contract an exterminator experienced in bee control if you're uncomfortable handling insecticides or have issues such as allergies to these chemicals.

Warning

  • Wear eye protection and avoid inhaling insecticide dust or the mist from liquid insecticides when treating bee holes.
