Is It a Pest Emergency? What to Do Right Now

Published October 18, 2026 · by David Kohlani, founder of ApexSmartAI

You open the back door and there is a wasp nest the size of a football above it. Or you hear scratching inside the bedroom wall at night. Or someone just spilled a bug spray and now feels sick. Your first question is not “which pest is this?” It is “is anyone in danger, and does this need help today?”

This guide is for homeowners and renters. It explains which pest problems are real emergencies, what to do while you wait for help, and what can safely wait for a normal appointment. It does not include do-it-yourself treatment steps, on purpose.

Call 911 first: a serious reaction to a sting

Most stings hurt but are not dangerous. A serious allergic reaction is different. The Mayo Clinic (insect sting first aid) says to call 911 “if anyone is having a serious reaction that suggests anaphylaxis, even if it’s just one or two” of these signs:

• Trouble breathing
• Swelling of the lips, face, eyelids or throat
• Dizziness, fainting or unconsciousness
• A weak and rapid pulse
• Hives
• Nausea, vomiting or diarrhea

The CDC’s workplace safety institute (NIOSH) describes anaphylaxis as “a severe and potentially life-threatening allergic reaction” that “requires immediate emergency care.” Don’t wait to see if it passes, and don’t call a pest company first. Call 911.

Possible pesticide exposure: Poison Help or 911

If someone swallowed, breathed in or spilled a pest control product on their skin or in their eyes, the U.S. Environmental Protection Agency (EPA) gives two clear rules:

• “Call 911 if the person is unconscious, having trouble breathing, or having convulsions.”
• Otherwise, “Call the Poison Control Center at 1-800-222-1222 for help with first aid information.”

EPA also says to “check the label for directions on how to give first aid,” so keep the product container nearby when you call. The Poison Help line is free and, according to the Health Resources and Services Administration (HRSA), it is “available 24/7 in over 100 languages” and connects you to your local poison center.

What to do right now, step by step

If nobody is hurt, slow down and take these steps in order:

1. Move people and pets away. Bring children and pets inside, or into another room, away from the nest, the animal or the product.
2. Don’t spray, swat, block or knock down anything. Leave nests, holes and burrows alone.
3. Don’t touch or pick up a rodent, alive or dead, and don’t sweep or vacuum droppings.
4. Close the door to the room where you saw the problem, if you can do it without going near it.
5. Note what you see from a safe distance: what it looks like, where it is, how many, and since when.
6. Call a licensed pest control professional and describe exactly what you saw.
7. Tell them about anyone at higher risk: a person with a known sting allergy, a baby, an older relative, or pets.

A stinging insect nest near a door, play area or inside a wall

A nest by the front door, over a deck, near a swing set or next to a window that people open every day is a real safety problem, even if nobody has been stung yet. Some nests are hidden. Oregon State University’s Pacific Northwest Pest Management Handbooks (PNW Handbooks) note that yellowjacket nests can be “in the wall voids of houses,” and that “by the end of summer, nests may contain hundreds or even thousands of workers.”

Signs of a nest in a wall include a steady stream of insects going in and out of one gap in siding or trim, or buzzing you can hear through the wall. Keep everyone away from that spot, keep windows near it closed, and don’t try to spray, plug or seal the hole. Call a licensed pest control professional, and mention if anyone in the home has had a bad reaction to a sting before.

A rodent in the living area

A mouse or rat in the kitchen, bedroom or a child’s room is upsetting, and it is a health concern. The CDC (hantavirus) says “people get hantavirus from contact with rodents like rats and mice, especially when exposed to their urine, droppings, and saliva.”

For now: keep children and pets out of the room, close the door, don’t touch the animal, and don’t sweep or vacuum droppings, which can stir up dust. If you do need to clean up after rodents, follow the Washington State Department of Health guidance (safely cleaning after rodents) step by step: air out the space for at least 30 minutes first, wear gloves, don’t sweep or vacuum, and soak droppings with a bleach solution (1 part bleach to 9 parts water) for 5 to 10 minutes before wiping. If there is a lot of contamination, or you’re not comfortable doing it, ask a licensed pest control professional.

Termite swarmers inside the house

Dozens of small winged insects near a window, or a pile of shed wings on the sill, can be termite swarmers. This is not a medical emergency, but it is worth a prompt inspection. Mississippi State University Extension (MSU Extension) says finding swarmers indoors “is a pretty good sign the building has an active termite infestation.”

Don’t spray them. If you can, take a photo or keep a few in a sealed bag so the inspector can see what they are, and call a licensed pest control professional to schedule an inspection soon.

What usually needs help today, and what can wait

Every company has its own after-hours rules, but this table is a sensible starting point:

Not sure which row you’re in? Call and describe what you see. A good pest control company will ask a few simple questions and tell you how soon someone should come.

What to tell the pest control company when you call

• What you saw, and where in or around the home
• How long it has been going on
• Whether anyone has been stung or bitten, or has an allergy
• Whether there are children or pets in the home
• Your address and the best number to call you back

If you get voicemail after hours, leave these details. If you need help right away, try another licensed company. If English isn’t your first language, ask whether they can help in Spanish; some companies can.

For pest control company owners: who answers this call?

If you run a pest control company, every call above lands on your phone, often at night while you’re asleep or on another job. We wrote companion pieces on the questions to ask on every pest control inquiry call and on handling emergency calls at night as a small contractor.

ApexSmartAI is a fully managed answering service for pest control companies. It answers your line 24/7 in English and Spanish (callers can switch mid-call), takes the job details and texts and emails them to you right after the call. It is built around your services, hours, service area and call rules. It can give the safety instructions you approve at setup, such as “keep children and pets away from the nest” or “if anyone is having trouble breathing, call 911.” It does not book appointments, dispatch, quote prices unless you approve the exact wording, or give treatment or chemical advice.

Pricing is $385 a month, $0 setup, 500 minutes included, then 43¢ a minute, month-to-month, with the first 7 days free starting the day your line goes live. See how it works on our pest control answering service page.
