Wasp Removal in Oshawa
For wasp removal in Oshawa, AstraHive Pest Control treats the full nest at dusk and removes it when it is safe, with a 30-day warranty on the treated spot. Health Canada says timing and safety decide the job, and Oshawa's climate normals show when the season ends.
What Health Canada says about wasp nests
Health Canada's advice starts early: inspect your yard and house in early summer for wasp activity or paper nests taking shape, because it is easier to discourage a single queen than to handle a full nest later. Wasps hunt protein for their larvae and are also drawn to sweet food and strong scents, so cover garbage, pet food and drinks outdoors.
On removal, it says that if a nest is not a health hazard it is best left until November or December, when it has been abandoned and can be removed with little risk. If it must come down while wasps are active, do it in the evening, when they are least active. Removal can be dangerous because of the risk of attack by a large group, and professional help is recommended. Insecticide treatment is effective, ideally after nightfall, and the label should carry a PCP number.

Health Canada's November and December window for abandoned nests lines up with those frost days. Between June and September a nest near a door, deck or soffit is a sting risk and the cost of waiting is a bigger colony. That is why we treat at dusk when a nest is in a place people use.

Frequently asked questions: Oshawa
When is the best time to remove a wasp nest?
Health Canada says a nest that is not a hazard is best left until November or December, when it is abandoned. If it must be removed while wasps are active, do it in the evening.
Can I remove a nest myself?
Health Canada says a homeowner with enough protection can, but that removal can be dangerous because of the risk of attack by a large group, and professional help is recommended.
What stops wasps nesting near my house?
Health Canada advises checking in early summer, covering garbage and food, and avoiding scented products, because a single queen is easier to discourage than a full nest.
Do you seal the entry hole afterwards?
No. We never seal the entry hole after treatment, because trapped wasps can chew through into the house. We remove the nest when it is safe.
What does the 30-day warranty cover?
Wasp and hornet nest work carries a 30-day warranty on the treated spot. A new nest in a different place is a new job.
