A paper wasp colony has a stage at which it is trivial. In April a founding queen has a comb roughly the size of a golf ball attached by a single stem, and no workers at all. With nothing on the nest to mount a response, ending it is the work of a moment. Every piece of wasp advice ever written leans on that stage, and it leans on an assumption nobody states: that somebody will be standing under the eave during the weeks it lasts.
In Holiday that assumption fails on a schedule. The main Holiday page works through the vacancy rate the 2020 census recorded here, which runs to 17.9 percent and reflects how many of these addresses are lived in for only part of the year. A house closed in May and opened in October is a house whose entire founding season runs with nobody present. Wasp and hornet control here is organized around that gap in the calendar rather than around anything unusual about the insects.
The Whole Arc Fits Inside One Closure
Lay the colony’s year against the closure and the overlap is nearly exact, which is what makes this a Holiday problem rather than a general one.
UF/IFAS describes founding queens starting new nests by themselves when spring comes, sometimes joined by sisters who become subordinate foundresses filling the roles of workers. The nest is founded and built through a phase with no worker force behind it. Then the first brood matures, workers take over construction, and the colony expands through the warm months. What hangs there by the end of the season is many insects rather than one, and they answer a disturbance together.
Now put dates on that. Founding runs at first warmth. Growth runs through the summer. Peak strength and sharpest defense land in late summer and early fall. A household closing at the end of April and returning in October is absent for every one of those, and arrives precisely at the stage where the nest is largest and best defended.
The colony did nothing out of the ordinary. It ran the same year it runs on the occupied house next door. What differed is that the occupied house had somebody carrying groceries under that eave in May.
The window that closes before you leave
There is a wrinkle in the timing that catches people who think of this as a spring chore, and it is worth putting plainly.
Florida rarely delivers the hard freeze that ends colonies outright in colder states. Mated queens overwinter in bark crevices, wood piles, and gaps in siding, and they start building when it warms rather than when a calendar says spring. In this climate that can mean combs are underway noticeably earlier than a northern intuition expects.
The consequence is that the useful walk is not something to get to next visit. If the house closes at the end of April, the founding stage has already begun on the surfaces you are about to stop looking at. The walk belongs in the same week as the shutdown, alongside whatever else gets done before the door locks.
Growth Is Not a Straight Line
Part of why the October version surprises people is that the colony does not grow evenly across the months nobody watched.
The founding phase is slow because one insect is doing every job. She builds, she forages, she tends brood, and there is nobody to divide the work with. A comb taking weeks to reach the size of a golf ball is simply the pace of a single animal doing all of it.
What changes that is the first brood reaching adulthood. Once workers are on the nest, construction and foraging are handled by a growing crew while the queen concentrates on laying, and expansion climbs with every worker added. The nest builds faster in August than in May because there are far more insects building it.
So the arithmetic is not five months of steady accumulation. It is a slow start that is easy to miss followed by an acceleration nobody was there for, which is why the gap between what a household expects and what is under the eave is wider than the months alone suggest.
Defense Grows With the Population
Size is the visible change over a closed summer. The change that decides how the removal goes is not size at all.
A founding comb has essentially nothing to defend it. There is one insect, and if she is away foraging there is nobody. That is the entire reason the spring version of this job is uneventful.
A mature colony is a different proposition, and the difference is behavioral rather than a matter of scale. Disturbing a nest with a worker population provokes a coordinated response rather than an individual one, because defenders release alarm signals that recruit nestmates to attack together. That is how one encounter becomes several stings rather than one.
Two things follow for a household walking back into an unopened house. Stings can escalate severely in sensitized people, including reactions requiring emergency care, so this stops being a nuisance question wherever anybody on the property has a sting history. And the object under the eave in October is not a bigger version of the April one. It is a different job with different handling, which is why our guide on finding a stinging insect nest starts with distance rather than removal.
Which Surfaces a Closed House Stops Reporting
Every house has surfaces that get looked at without anyone deciding to look, and shutting the door retires all of them at once.
An occupied Holiday household passes under the porch ceiling several times a day. It works the shutters. It lifts the cover off the grill. It parks under the carport, hoses the walk, waters the pots by the door, and carries the trash past the same corner of soffit twice a week. None of that is inspection, and all of it produces information. Somebody eventually looks up.
Close the house and those surfaces are not inspected less carefully. They are not inspected at all, and the ones that go quiet are the ones a founding queen prefers, because sheltered overhead surfaces near where people live are what she is selecting for.
The list runs short and specific on this housing stock: the porch and carport ceilings, the soffit line and its returns, the shelter behind every shutter, a lanai frame, the grill cover left on all summer, the space under a boat cover, the lip above a garage door, and any shed at the back of the lot. On a closed house each one is unobserved for five months.
Stored things are surfaces too
The items a household puts away for the season create sheltered overhead space that did not exist during the occupied months.
A grill cover left in place forms a dry protected void with a roof on it. A boat under a cover does the same on a larger scale. Patio furniture stacked and sheeted, a folded umbrella left standing, a kayak turned over on a rack, and anything tarped against the shed all produce dry shelter, out of the wind, undisturbed until October.
None of that is a mistake. Putting things away before a closure is the right instinct. It just means the first days back include lifting covers deliberately rather than pulling them off in one motion, and doing it in the cool of the morning when colony activity is lowest.
Ground Level Runs the Same Calendar
Eaves are not the only thing a closed season leaves alone. Some of what settles in over a Holiday summer is at ankle height, and nobody finds it by scanning a roofline.
Yellowjackets want an enclosed hollow, and five unattended months supply plenty. A hole in the soil at the back fence. The gap where a slab has lifted at one edge. Underneath whatever got stacked against the shed in April and never moved. Each reads as a yard needing tidying, and each can have a colony in it.
What makes this a returning owner’s problem is the first yard work after a closure. Five months of grass and grown in beds get dealt with in the week somebody arrives, usually with a mower, usually when ground colonies are at their strongest. Walking into a nest entrance gives you a second or two of warning, which is enough to stop and retreat. Riding over one gives you none, because the machine has passed the opening before the first defenders are up.
The countermeasure costs two minutes. Walk the ground you are about to cut before you drive it, especially any stretch untouched since spring. Look for insects going in and out of one point in the soil, and if you find that, the mowing waits.
The First Hours Back Are the Whole Inspection
The return is where this page turns into something a household can act on, and the sequence matters because the exterior comes before the door.
Start from the driveway before anybody walks the perimeter. Stand back, put the light behind you, and watch the eave lines, the porch ceiling, and the shed for a couple of minutes. You are reading traffic rather than structure, because a consistent flight line to a single point is easier to see from a distance than a comb in a shadow. A flight line with no visible nest deserves more caution rather than less, since void and ground colonies are the ones people stumble into.
Then work the covered items, in the morning, lifting rather than yanking, with a way to step back from each one.
Only then the close look, and only at what the distance read left unexplained. Grey papery cells in an open umbrella shape, slung beneath a soffit on a single stem, mean a colony whose defenders have had all summer to accumulate. Something built of dried dirt on a sheltered wall is the work of a mud dauber, which is solitary and generally uneventful to remove. Paper is one conversation and mud another, and telling them apart from ten feet saves a call.
Our guide on when to call covers where the line sits between a household job and a scheduled one. On a house shut since spring the line sits closer than in April, because everything found in October has had the full run of the season.
Covering the Exterior While the House Is Shut
The useful part of this page is that the gap is fillable, and filling it does not require anybody to be living in the house.
Nothing this job requires happens indoors. Reading an eave line, checking a soffit return, and putting product on sheltered overhead surfaces are done standing in the yard, so a locked door stops none of it. Keep those visits running through the closure and the surfaces nobody is home to watch get watched anyway, by somebody whose reason for being there is to look up. A comb caught on one of those passes is barely a task.
That is a different proposition from a single visit in October. A visit after the fact is a removal, performed on a mature colony, at whatever height the queen chose in April. A visit mid closure is prevention, performed on a comb with no defenders, and the two are not the same job even at the same address.
One qualification belongs here, because the alternative is treating every nest as an emergency. A comb tucked high in a shed gable at the far corner of a lot spends the season hunting other insects and bothers no one. Removal is earned by where a nest sits relative to a door, a gate latch, or the step where somebody carries luggage in from the car. The question is who passes underneath it, not what built it.
The other half is denying the surfaces in the first place. An exterior barrier maintained on the sheltered horizontal surfaces where founding queens start makes those surfaces a worse choice, and it does that work through the weeks nobody is present. Our seasonal pest proofing guide sorts the year’s maintenance by season, and a shuttered house should read the spring entries before locking up rather than after.
On cost: our pricing page covers how a program for a seasonal property is put together. Nobody charges you for the visit that produces the number, and no work begins until that number has your agreement.
A colony that ran its entire year without a witness is not a worse colony. It is an ordinary one that never met the interruption most houses provide by accident.

Wasp & Hornet Control Questions in Holiday
We lock up in May and open in October. Which part of a wasp colony's year are we missing?
All of the easy part. A founding queen starts her comb at first warmth, works alone for weeks with no workers to help or defend, and the nest stays roughly golf ball sized through that stretch. Then workers emerge and take over building, the colony grows through the summer, and defense sharpens as the population does. Those two stages are almost exactly bounded by a May to October closure. You are away for the founding, away for the growth, and back for the result. Nothing unusual happened at the house. You simply arrived after the only chapter that was cheap to interrupt.
Is there any way to know what happened while we were gone before we walk up to the house?
Yes, and it is worth doing from the driveway rather than from the porch. Stand back with the light behind you and watch the eave lines and the porch ceiling for a couple of minutes. What gives a colony away at a distance is the traffic rather than the nest, because insects returning home fly a consistent line to one point instead of wandering. From twenty feet you can read that line more easily than you can from underneath it. Binoculars are a reasonable tool. The thing to avoid is walking the perimeter close to the wall looking up, which is how people meet a mature colony at arm's length.
Whoever checks on the house never mentions wasps. Should they be finding them?
Not usually, and it is not a failure on their part. A property check is normally an indoor errand: look for a leak, make sure the air is running, confirm nothing is obviously wrong, lock up and go. Nothing about that routine involves standing outside looking up at the underside of a soffit, and a founding comb in April is small and quiet enough that it would not catch the eye of somebody walking past it to a door. If you want the exterior covered, it has to be asked for as its own task, and April and May are the two visits where asking is worth the most.
Does a Florida winter knock any of this back for us?
Not the way it does further north. Where hard freezes are reliable they end colonies outright and the following spring starts from nothing but overwintered queens waiting out real cold. Florida rarely delivers that, so mated queens ride out mild winters tucked into bark, wood piles, and gaps in siding, and they begin building the moment it warms rather than waiting for a season to turn. For a part year household that matters in a specific way: the founding stage can be underway well before the date you had in mind for closing up, so the walk belongs before you leave rather than as a spring errand you get to next time.
The nest is up under the second storey eave. Can we take it down ourselves when we get back?
We would rather you did not, and the reason is the ladder as much as the colony. A mature nest in October has a standing population of defenders that respond as a unit when the nest is disturbed, and stings can escalate severely in anyone sensitized to them. Add height to that and the fall becomes the larger risk, because a person who takes a first sting fifteen feet up does not make a calm decision about coming down. In a house that has been closed all summer there is also frequently nobody else on the property. Looking from the ground is genuinely useful and costs nothing. Reaching is where it stops being a chore.
