When Do You Need an Emergency Exterminator?
Some pest situations cannot wait for a scheduled appointment. Here are the scenarios that require immediate professional response.
Wasp Nest Near Children or Allergic Individuals
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.
Rodent Seen in Food Preparation Area
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.
Bed Bug Discovery Before Guests Arrive
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.
Cockroach Infestation in Restaurant
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.
Aggressive Pest Threatening Health or Safety
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.
