Pest Control Seasons: When Each Call Surge Hits
Ask any pest control owner and they’ll tell you the phone has seasons. Some weeks it barely rings. Other weeks every call is a homeowner who just saw something alarming and wants someone out today.
Plenty of websites claim the phone “triples” in a certain month, but they rarely show where the number comes from. This article sticks to what university extension services actually say about when three common pest problems peak: termite swarms, stinging insects and mice. Then it covers how to get your phones ready for each one.
One rule before we start: timing varies by region. The dates below are examples from the extension services named, not a national calendar.
Spring: termite swarm calls
Termite swarms are one of the most alarming things a homeowner can see: dozens of winged insects near a window, or a pile of wings on the floor. Mississippi State University Extension (MSU Extension) says “eastern subterranean termites normally swarm in the spring.”
How early depends on where you are. A 2025 MSU Extension article (MSU Extension, 2025) says swarm season “can begin as early as late January or February along the Gulf Coast” and “extend into May and potentially early June in north Mississippi.” The same article says finding swarmers indoors “is a pretty good sign the building has an active termite infestation.”
That’s why these callers are anxious. They want to know if their house is being eaten. Your phone answer should be calm, take the details, and offer an inspection. It should not confirm “yes, it’s termites” before anyone has looked. We explain why in questions to ask on every pest control inquiry call.
Late summer: stinging insects
Yellowjacket colonies grow all summer. The Pacific Northwest Pest Management Handbooks from Oregon State University (PNW Handbooks) say, “It is at this time of the year (August-September) that they are most troublesome and dangerous,” and that “by the end of summer, nests may contain hundreds or even thousands of workers.” North Dakota State University Extension (NDSU Extension) agrees: “Yellowjackets are more aggressive during August and September and more likely to sting people.”
Those calls come with real safety stakes. A family with a nest by the back door, or inside a wall, may have someone with a sting allergy. Whoever answers should be ready with two approved lines: if anyone shows signs of a serious reaction, call 911 (the Mayo Clinic lists the signs), and keep everyone away from the nest until a licensed technician arrives. Our homeowner guide, is it a pest emergency?, covers this in plain language.
Fall: mice move indoors
When nights get cold, rodent calls follow. MSU Extension (house mouse) puts it simply: “As cooler weather arrives, mice are looking for any source of heat and food they can find.”
A mouse in the kitchen or a child’s bedroom feels urgent to the caller, and it is a health concern: the CDC (hantavirus) says people get hantavirus from contact with rodents, “especially when exposed to their urine, droppings, and saliva.” Fall callers often ask whether they should clean up droppings themselves. Your phone answer should not improvise. It can point them to the Washington State Department of Health rodent cleanup guidance (no sweeping or vacuuming, air the space out first) or tell them your technician will advise on site.
The three surges at a glance
| Season (example region) | What callers report | Source | Phone priority |
|---|---|---|---|
| Late Jan–Feb on the Gulf Coast to May–early June in north Mississippi | Winged insects or wings near windows | MSU Extension | Offer a prompt inspection |
| August–September (Pacific Northwest, North Dakota) | Yellowjacket nests, stings | OSU PNW Handbooks, NDSU | Safety lines first, then same-day if possible |
| As cooler weather arrives (Mississippi) | Mice in kitchens, walls, attics | MSU Extension | Same or next day for living areas |
Timing varies by region: check your own extension service
A spring that starts in February on the Gulf Coast may start much later farther north. Yellowjacket peaks reported in Oregon and North Dakota won’t match every state. Mice move in “as cooler weather arrives,” and that date depends on where you work.
The best source for your area is usually your state’s land-grant university extension service. Look up its pest pages, note the months it gives, and compare them with your own call records from last year. Your own records beat any vendor chart.
How to staff your phones for a surge
The surge always arrives at the same time your technicians are busiest. The U.S. Bureau of Labor Statistics (BLS) notes that for pest control workers, “working evenings and weekends is common.” A few weeks before each season, work through this list:
- Pull last year’s call log. Mark the weeks the phone got busy and which pests drove it.
- Decide who answers when you can’t. Office staff, a family member, voicemail, or an answering service. Write it down.
- Write your safety lines once. The 911 line for serious sting reactions and the Poison Help line (1-800-222-1222, per EPA) for possible pesticide exposure. Keep them identical for everyone who answers.
- Set your priority rules. Which reports get same-day service, which get next available, which get a callback.
- Plan after-hours coverage. Decide whether night calls get a callback first thing in the morning or an on-call technician.
- Block callback time. Set a fixed slot each day so messages don’t wait until the weekend.
- Check your ads. If you run Google Local Services Ads, “Pest control services” is an eligible category, and you “only pay when a customer gets in touch from your ad” (Google). An unanswered call from a paid lead is money spent for nothing.
If many of your seasonal callers speak Spanish, plan for that too. Our guide on bilingual answering for service businesses covers the options.
Covering the phones when the season hits
If you’re weighing staff against a service, our comparison of a receptionist vs an answering service lays out the trade-offs.
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, so a busy week doesn’t turn into a pile of voicemails. It is built around your services, hours, service area and call rules, and it can give the safety instructions you approve. 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.

Frequently asked questions
When is termite swarm season?
It depends on the region. Mississippi State University Extension says eastern subterranean termites normally swarm in the spring, starting as early as late January or February on the Gulf Coast and extending into May and possibly early June in north Mississippi.
When are yellowjackets most aggressive?
North Dakota State University Extension says yellowjackets are more aggressive during August and September, and the Pacific Northwest Pest Management Handbooks call August and September the time they are most troublesome and dangerous.
Why do mouse calls increase in the fall?
Mississippi State University Extension says that as cooler weather arrives, mice look for any source of heat and food they can find, which often means moving into homes.
