Carpenter bees

A special case today involving carpenter bees!

We were recently called to a residence in Outremont regarding this type of infestation. The homeowner had noticed a buildup of sawdust on the patio door threshold. When a technician arrived for inspection, they observed bees entering under the awning attached to the wall, directly above that same patio door.

A nest was developing inside the wooden structure supporting the awning!

The technician performed a targeted insecticide injection, which appears to have resolved the issue.

(Please allow at least 48 hours for full results.)

For hidden nests, you should NEVER block the entry point. Instead, a contaminant insecticide must be applied so that the insects’ natural activity carries the product back to the source (the nest).

In all cases involving hymenoptera nests (bees, wasps, hornets, or horseflies), it is essential to properly identify the entry point and apply an insecticide to “contaminate” that area. As insects move in and out, they come into contact with the product and carry it directly back to the nest.

Physically blocking an entry point (with caulking, expanding foam, or mesh) does not solve the problem and will force the colony to find another exit… which could very well lead inside the home!

If you attempt to eliminate this type of nest, always proceed with caution and proper protection.
