Stinging insects are the one category where waiting genuinely costs you something, and in Springfield the calendar is unusually sharp.
A colony that is a manageable nest in June is a large one in August, and late in the season yellowjackets become materially more aggressive — not because they turn mean, but because the colony’s food supply shifts and the workers start foraging harder and defending more readily. The nest you noticed in July and meant to deal with is a different proposition by Labor Day.
We prioritize stinging insect calls for that reason, usually same week and often sooner.
Old Springfield soffits are ideal wasp real estate
Springfield built most of its houses between about 1870 and 1930, and that architecture hands stinging insects a great deal.
Deep overhanging eaves and decorative brackets give paper wasps sheltered, rain-protected surfaces to build under. Big covered porches — a defining feature of this housing — produce nests directly above where people sit. Century-old soffits and fascia have opened up at the seams over the decades, and a gap of a quarter inch is an invitation to a yellowjacket colony to nest inside the wall or soffit cavity rather than out in the open. Attic vents with failed screening do the same job.
Nests inside a wall or soffit void are the ones that need professional handling, and the reason is worth spelling out: the visible entry hole is not the nest. Spraying into the hole from a can typically kills the workers coming and going while leaving the colony intact behind the sheathing, and it makes the remaining population defensive at the exact spot you are standing. It also, in old wall cavities, has a habit of driving them inward — and a colony that finds its way through a plaster wall into a bedroom is a genuinely bad afternoon.
What you are actually dealing with
The species matters, because the treatment does.
- Paper wasps. The open, umbrella-shaped comb hanging under an eave, a porch ceiling, a deck rail or a grill lid. Relatively unaggressive away from the nest, and the easiest to deal with early.
- Yellowjackets. The problem species here. They nest in the ground, in wall voids and in soffit cavities, and they are the ones responsible for most late-summer stings. Aggressive in defense of the nest, and capable of stinging repeatedly.
- Bald-faced hornets. The large gray football-shaped paper nest in a tree or under an eave. Genuinely defensive and best left entirely alone.
- Cicada killers. The very large solitary wasps that alarm people every July, particularly on the sandy well-drained ground on the west side of town. They are almost entirely harmless and the males that dive at you cannot sting at all — our guide explains why they usually need no treatment.
- Carpenter bees. Not a wasp, but the same call. They drill clean holes into unpainted softwood — deck rails, porch trim, soffit boards — and Springfield’s older woodwork and 1980s decking give them plenty to work with. Woodpeckers then open the galleries up chasing the larvae, which is where the real damage comes from. See our carpenter bee page.
Honeybees are a separate matter. We do not exterminate honeybee colonies — if you have a genuine swarm or an established hive, that is a job for a beekeeper, and we will say so and point you toward one.
Ground nests, and the lawnmower problem
The most common serious sting incident we hear about in Clark County involves a mower or a string trimmer.
Yellowjackets nest in the ground — in an abandoned rodent burrow, under a landscape timber, at the base of a shrub, in the gap beside a set of steps. The entrance is often a hole no wider than a thumb, and you can walk past it for weeks without noticing. Then a mower goes over it and the vibration brings the whole colony out at once.
The well-drained terrace ground on the west side of Springfield and out toward Enon is especially good for ground nesting, which is why that side of town produces a disproportionate share of these calls. If you are mowing an area you have not mowed in a while, particularly in August, it is worth walking it first and watching for a steady stream of insects going in and out of one spot in the ground.
If you find one: mark it from a distance, keep people and pets off it, and do not pour anything into it. Gasoline down a yellowjacket hole is a genuinely dangerous folk remedy that contaminates soil and starts fires, and it frequently fails to reach the nest anyway.
How we handle it, and when you should not
Our approach depends on the nest. Exposed paper nests get treated directly and removed. Ground nests get the entrance treated with the colony intercepted at the point they all pass through. Void nests in walls and soffits get treated through the cavity rather than the visible entry, and then — this is the part people skip — the entry gets sealed after the colony is dead, not before. Sealing a live nest in is how you get insects chewing through into a bedroom.
We also remove the nest material where it is practical to do so, because an abandoned nest in a wall void attracts dermestid beetles and can produce a lingering odor and staining.
Please do not do this yourself if any of the following is true: the nest is inside a wall or soffit, it is above ground-floor reach and would need a ladder, it is a bald-faced hornet nest, it is in or beside a doorway people use, or anyone in the household has a known sting allergy. A ladder plus a defensive colony is the combination that produces the injuries, and it is not the sting that does the damage.
Nest on a Springfield porch? Do not wait for August.
Stinging insect treatments start at $129, with the harder access jobs at $199. Stinging insects get priority scheduling because the problem escalates while you think about it. The Protection Plan runs about $63 a month bundled and carries the re-treatment guarantee between scheduled visits.

Frequently asked questions
Why are the wasps so much worse in late summer?
The colony has been growing all season and peaks in size in late summer, and at the same time its food supply shifts, so workers forage harder and defend more readily. Same insects, much shorter fuse. A nest handled in June is a far smaller job than the same nest in September.
There is a hole in my lawn with wasps going in and out. What now?
Ground-nesting yellowjackets. Mark it from a safe distance, keep people and pets away, and do not mow near it. Do not pour gasoline or anything else down the hole — it is dangerous, illegal to do with fuel, and often does not reach the nest. Call us.
Can I just spray the hole in my soffit myself?
We would rather you did not. The entry hole is not the nest — a can sprayed into it usually kills the workers passing through, leaves the colony intact behind the sheathing, and makes them defensive right where you are standing. In old wall cavities it can also push them inward, toward the inside of the house.
Should I seal the hole once they are dead?
Yes — but only once they are dead. Sealing a live colony in is how wasps end up chewing through plaster into a room. We treat first, confirm the colony is finished, then seal.
Huge wasps are hovering over my lawn and dive at me. Dangerous?
Almost certainly cicada killers, and almost certainly not. They are solitary, the males that dive at people have no sting at all, and the females are not interested in you. They favor the sandy well-drained ground on the west side of town. Usually the right treatment is none.
Do you remove honeybees?
We do not exterminate honeybees. If you have a swarm or an established hive, that belongs with a beekeeper and we will point you toward one rather than treat it.
What about the holes in my deck rail?
Carpenter bees — clean, round, roughly finger-width holes in unpainted softwood. The bees themselves do modest damage; the real problem is woodpeckers opening the galleries up to get at the larvae. Springfield’s older trim and 1980s decking are prime targets.
How fast can you come out?
Stinging insects get priority — usually the same week and often sooner, because unlike most pests these get meaningfully more dangerous while you wait.
