Spraying the entry point kills a few workers. The queen is untouched and the colony rebuilds within days — angrier than before. You have to get the product deep inside where the nest actually lives.
Call 905-925-8427 — Same-Day ServiceA queen starts the colony alone in spring — a nest the size of a golf ball. By midsummer that same nest can hold 1,500 to 15,000 wasps depending on the species. Yellow jackets nest inside wall voids, underground, and in attic spaces. You see them going in and out of a small gap. That gap is just the entrance. The nest is deep inside — sometimes two to three feet into the wall or the ground.
Spraying the entrance does nothing. The colony is not there.
Unlike bees, wasps do not die after one sting. A single wasp can sting multiple times. When threatened, they release an alarm pheromone that signals the entire colony to attack. For most people that means pain and swelling. For someone with an allergy — it means anaphylactic shock. That is a life-threatening emergency.
Most people try to spray the entrance where wasps are going in and out. Spraying the outside kills a few workers. The queen is untouched. The colony survives — and the workers that are left become more aggressive. You have to get the product deep inside where the nest actually lives.
If the nest is accessible and visible — we remove it completely. No nest means no structure for the colony to rebuild around.
If the nest is inside a wall void, ceiling void, or deep in a structure — we use a professional pump to push a large volume of pesticide dust through the entry point. The dust travels deep inside and creates a cloud throughout the entire void. Workers carry the dust back to the queen. Queen dies. The whole colony collapses. It is both a bait and a contact kill at the same time — reaching areas no spray ever could.
If there is an immediate risk — a patient in the home with a severe allergy, or a highly aggressive colony — we use a ULV pesticide to rapidly eliminate the active population on the spot. Brings the threat level down immediately while the dust finishes the colony.
Every product used and every zone treated is recorded in the service report.
Most companies spray the entry point and leave. The queen is still deep inside the wall. The colony rebuilds within days. The only method that eliminates the colony is getting product deep into the void where the nest actually lives.
