Call Our Emergency Line Now
Pest emergency? Our technicians are on standby right now — call for immediate dispatch.
Some pest situations cannot wait for a scheduled appointment. Here are the scenarios that require immediate professional response.
An active wasp or hornet nest near a play area, entrance, or anywhere children or allergy sufferers are present is a medical emergency. A single sting can trigger anaphylaxis. We respond within 2–4 hours.
A mouse or rat in a kitchen — residential or commercial — contaminates food surfaces with bacteria including Salmonella and Hantavirus. For restaurants, this can trigger MAPAQ closure. Act immediately.
Found bed bugs hours before guests, tenants, or hotel guests arrive? We offer same-day inspections and can often begin treatment the same day. Discreet service available.
A cockroach sighting before a MAPAQ inspection or during service hours can shut down your business. We offer after-hours emergency treatment with full documentation for health inspectors.
Any pest situation that poses an immediate threat to the health or safety of occupants — including aggressive hornets, large rodent infestations, or severe cockroach outbreaks — qualifies for emergency response.
From your call to treatment — fast, professional, and guaranteed.
Call 514-809-1999 any time of day or night. A real person answers — not a voicemail. We assess your situation immediately and dispatch the nearest available certified technician.
Our certified technician arrives within 2–4 hours for emergencies. We conduct a thorough inspection, identify the pest and severity, and provide a transparent written quote before any work begins.
