Wasps and Carpenter Bees
These seasonal pest can disturb your family and damage your house. Professional treatment is recommended.
While there are many varieties of wasps in Ontario the most common wasps are yellow jackets, hornets, and paper wasps. The queen is responsible for nest establishment and egg laying. Only one queen is present during most of the season. Most of the colony’s inhabitants are female Workers equipped with stingers. Wasps are fast moving, with with the ability to sting repeatedly. Wasps are typically feared as more people die in North America each year from bee and wasp stings than from all other venomous bites such as snakes and spiders combined.
Our technician will inject insecticide into the nest to kill all stages of wasps within the nest. We ask that you stay away from the area for 24 hours after treatment. Please note: do not seal the hole of active wasp nests. Once the nest has been exterminated and you are sure it is inactive, it is OK to then seal the hole.
- Strong perfumes and colognes will attract bees and wasps.
- Pick up fallen fruit under fruit trees if possible.
- Keep garbage cans and bins washed
The carpenter bee is often confused with the bumble bee. The key difference is that the abdomen is hairless and it is metallic blue and black in colour. The damage seen by the naked eye is almost perfectly round holes approximately a ½” across. The carpenter bee normally makes its home in facia, siding, porch beams, exterior columns, fence posts and trees. The female will bore into wood and quickly excavate at a right angle to the entrance hole to create a brooding chamber. The female will provision approximately 6 cells with pollen and food for egg and larval development. It takes about 36 days before the egg and larvae emerge as adults. The males do not have stingers, but will hover and attempt to intimidate to defend the nest, while the females will only sting if mishandled or molested, or to defend the nest.
Carpenter Bee Treatment
There is no preparation required for a carpenter bee treatment. The Technician will spray or dust depending on what they thinks is necessary.
Carpenter Bee Prevention
- Carpenter Bees attack unfinished wood under decks, sills, and decks first. Varnish or paint these wood surfaces to make them less attractive to these bees. A fresh coat of paint is unattractive to a Carpenter Bee.
- Seal as many exterior openings as possible. The Carpenter Bees are looking for cracks that will protect entrances. Seal and caulk these cracks and crevices.
- Carpenter Bees will reuse holes from the previous season. Cauk these holes in the fall, after the carpenter bees have emerged.
