Below is what Ontario customers get when they book mosquito control with us — local dispatch, and the exact process we use across California.
Mosquitoes in California complete a life cycle in as little as seven days when standing water is present. Females lay eggs in any container holding water for more than a few days, from clogged gutters and birdbaths to irrigation drip trays and low spots in yards. Homeowners first notice increased biting at dusk and dawn near patios or entry points, often mistaking the problem for a neighbor's yard rather than on-site breeding.
The obvious DIY approach of spraying adult mosquitoes fails because new adults emerge daily from untreated water sources. Foggers and retail sprays provide only hours of relief while eggs and larvae continue developing. Operators prioritize locating and eliminating every breeding site before any chemical application, because source reduction stops the next generation at the root.
Mosquito Control Services We Offer in Ontario
✓Standing Water Source Reduction
Operators locate and eliminate containers, drainage issues, and low spots that hold water long enough for mosquito larvae to develop.
✓Larvicide Application
Targeted larvicide is placed in persistent water sources that cannot be drained, preventing larvae from reaching the adult stage.
✓Perimeter Barrier Treatment
Residual products are applied to vegetation, fences, and building exteriors where adult mosquitoes rest between blood meals.
✓Event Treatment
Timed perimeter applications reduce biting adults ahead of outdoor gatherings without interfering with food or seating areas.
How It Works in Ontario

Source Reduction
Breeding sites are emptied, altered, or screened; larvicide is applied only where water cannot be removed.

Perimeter barrier treatment targets resting adults in shrubs, under eaves, and along fence lines.

Follow-Up Visit
A return inspection checks for new water accumulation and confirms the population has dropped.
