Does NBS-30 Kill Carpenter Bees?

No! NBS-30 is a repellent; not an insecticide. NBS-30’s strong odor repels insects. In addition, treatment of holes drilled by Carpenter Bees as described below is necessary to achieve success with the NBS 30 product.

To treat with insecticide acquire the following items:

  • Appropriate insecticide (like Sevin Dust)
  • Plastic syringe or  Turkey baster
  • Aluminum foil
  • Small star-head screw driver
  • Log home caulk
  • Appropriate protective gear for your face, hands, and body.
  • Plumber’s Snake or coat hanger
1. Fill syringe with insecticide. 2.Insert insecticide in the Carpenter Bee hole. 3. Wait several days. 4. Roll the aluminum foil into a small ball. 5. Insert the aluminum foil on the tip of the screwdriver and stuff it into the Carpenter Bee hole. 6. Seal the hole with log home caulk. 7. Follow the above procedure with every hole that the Carpenter Bees have drilled.

Application Tips


  • Entire contents of a one pint can of NBS-30 should be added to 5 gallons of paint or stain.
  • Mix according to label directions for use with smaller quantities of paint or stain.
  • When used with multiple coats of paint or stain, always mix NBS-30 with the last coat applied.

How Does NBS-30 Effect Exterior coatings?


  • Sheen, curing time and luster of the coating may be changed slightly and would be most noticeable in pure white paint.
  • High gloss coatings are reduced to semi-gloss.
  • NBS-30 is not for use with any Perma Chink Systems water-based exterior products such as Lifeline Advance Satin or Gloss Top Coat.

Can NBS-30 Be Mixed With Water?


Yes! NBS-30 can be mixed with water and sprayed on any stained or painted wood surface. Mix a one pint container of NBS 30 with five gallons of water and apply the product with pump sprayer. When this mixture is applied to wood in an exposed area it is subject to being washed off in a heavy rain. Reapply as necessary every 30 to 60 days. NBS-30 works best when used as a stain or paint additive because the coating locks the product on to the wood surface.

It is safe for pets and people.   Caution: This product is toxic to fish. Keep out of lakes and streams or areas designated for commercial  honeybee farming.
