The visible entry point is just a door. The colony is feet inside the wall, ground, or ceiling void. Spraying the entrance kills a few workers and makes the rest more aggressive. You have to get the product deep inside where the nest lives.
Call 905-925-8427 — Same-Day ServiceYellow jackets nest deep inside wall voids, underground burrows, and attic spaces. One nest in April becomes thousands by August. They sting repeatedly without dying. When threatened, a single yellow jacket releases an alarm pheromone that mobilizes the entire colony instantly.
For most people that means pain and swelling. For someone with an allergy — it means anaphylactic shock. Never attempt DIY removal of an active yellow jacket nest inside a wall or underground.
We identify whether the nest is in-wall, underground, in an attic void, or in another cavity structure.
We inject professional pesticide dust through the entry point. The dust fills the entire void — reaching feet inside where the nest actually is. Workers carry the product back to the queen. Queen dies. Full colony collapses from within.
Where the nest can be physically removed, we remove it to prevent future colonies from establishing in the same void.
For immediate allergy risk or highly aggressive colonies — we use ULV knockdown to eliminate the active surface population on the spot.
Spraying the entry point alone does not work. The colony is feet inside the wall, ground, or ceiling void. Dust injection is the only method that reaches where the nest actually lives and delivers the product directly to the queen through the workers.
