Noise in the ceiling after dark is one of the few pest problems where the company you instinctively call may not be legally allowed to solve it. In Virginia, treating insects and rodents runs on a pesticide business licence from one state agency; capturing and removing wildlife runs on a permit from a different one. A squirrel in your attic is the second kind.
The timing of the noise narrows the animal considerably, and the animal decides which credential matters.
This is general information. What is above your ceiling can only be established by someone who goes up and looks.
What the timing tells you
| When you hear it | Most likely | What it sounds like |
|---|---|---|
| Just after dawn and again at dusk | grey squirrels | rolling, scampering, hard scratching; sometimes a nut dropped and rolling |
| Full dark, heavy | raccoons | thumping, dragging, chittering; heavy enough that you look up |
| Full dark, light and fast | mice or rats | rapid scratching in wall voids, gnawing, no weight to it |
| Dusk, brief, then silence | bats leaving to feed | fluttering, scrabbling near the eaves rather than overhead |
| Steady, daytime, no pattern | flying squirrels, or a bird in a vent | varies |
Squirrels are the daytime animal. They are active at first light and again in the late afternoon, and they go quiet at night. If the noise is loudest when you are trying to sleep, squirrels are the less likely answer.
Raccoons announce themselves by weight. A raccoon moving across joists is unmistakable once you have heard it — nothing else in a Virginia attic is that heavy.
Bats are the quietest and the most misread. What people notice is rarely the bats themselves but the sound near an eave at dusk, or a smell later, or a single bat that finds its way into a room.
The credential most people check is the wrong one
This is the part that has real money attached, and almost nothing written for Virginia homeowners says it plainly.
The pesticide business licence issued by the Virginia Department of Agriculture and Consumer Services — the registry every page on this site tells you to search, with its categories 7a and 7b under 2VAC5-685-70 — governs the application of pesticides. It is the right check for termites, roaches, ants and bed bugs.
It does not authorise the removal of wildlife.
Under 4VAC15-30-50, the people permitted to capture, hold, transport, release and where necessary humanely dispatch wildlife are department employees, federal wildlife staff, local animal control officers, and individuals operating under a commercial nuisance animal permit issued by the Virginia Department of Wildlife Resources under §§ 29.1-412 and 29.1-417 of the Code of Virginia.
So a company handling the squirrel in your attic needs a VDWR commercial nuisance animal permit. A homeowner who dutifully searches the VDACS registry, finds the company listed, and books the job has verified a real licence for a different activity.
Ask for both. Many established firms hold both, and the ones that do will answer the question without hesitation. The question itself tells you a great deal.
Poison is unlawful here for everything except rats and mice
Not a matter of preference or humaneness — a regulation, and one worth quoting because it is short and unambiguous. 4VAC15-40-50 provides:
It shall be unlawful to put out poison at any time for the purpose of killing any wild birds and wild animals, provided that rats and mice may be poisoned on one's own property.
The exception covers the Commissioner of Agriculture and Consumer Services, the U.S. Department of Agriculture, their representatives and cooperators, and those assisted in a control programme authorised by those agencies. It does not cover a homeowner, and it does not cover a company treating your attic.
Two consequences follow, and they run in opposite directions.
For squirrels, raccoons, opossums and groundhogs, poisoning is simply out. Anyone offering it is offering something unlawful. The lawful methods are exclusion and trapping under permit.
For rats and mice it is permitted — and still often the wrong choice indoors. A poisoned rodent dies where it happens to be, which is frequently inside a wall or above a ceiling, and then you have a smell that lasts for weeks and no way to reach it. This is the single most common cause of that particular problem.
Bats are a separate case, and the calendar matters
Three bat species found in Virginia are federally endangered, and the Endangered Species Act prohibits harming, harassing, pursuing, trapping, capturing or killing them.
The Department of Wildlife Resources is direct about method: exclusion is the only good way to remove bats from a structure. You find the exit by watching the building in the evening as they leave to feed, then close the opening once you are certain none remain.
And the season decides when you may close it. VDWR cautions that from May through August, young may still be present in the roost. Sealing the opening in that window traps flightless young inside — they die in the structure, and the adults, shut out from their pups, work at the building to get back in. The right months to exclude are outside that window.
Under 4VAC15-30-50 it is not lawful to transport, release or relocate a bat anywhere other than the property where it was caught. A company promising to take your bats somewhere pleasant and let them go is describing something Virginia does not permit.
If a bat is found in a room with people, the Virginia Department of Health recommends capturing it and having it tested for rabies. VDWR notes that fewer than half of one per cent of bats carry rabies — the recommendation is caution, not alarm. Use heavy leather gloves if you must handle it at all, and do not release it before it can be tested.
What to do tonight, and what to leave alone
Note the time and the character of the noise, for three or four nights if you can. This is the single most useful thing you can hand whoever comes, and it costs nothing.
Look at the outside of the house in daylight. Gable vents with the screen pushed out, a lifted roof edge, a soffit gap, a chewed corner of fascia, a gap where a pipe or a wire enters. Photograph anything that looks disturbed.
Watch the eaves at dusk if you suspect bats. Twenty minutes before dark, from a distance, looking for animals leaving rather than arriving.
Do not seal anything yet. Closing the entry while animals are inside is the most expensive mistake available here: they die in the structure, or they tear a new opening to get out, and both cost more than the exclusion would have.
Do not put out poison. Unlawful for wildlife, and for rodents it creates the wall-cavity problem described above.
Do not go up without a light and a plan. Insulation hides joists, and a raccoon defending young is not a thing to meet by surprise.
What this means for you specifically
If you own and live in the home
The animal is the visible half of the problem. The opening it used is the other half, and only one of the two comes back next year.
Your action: get an inspection that identifies entry points and quotes the repair, not just a trapping visit. Ask which permit covers the work, and ask what is done about the opening once the animal is out.
If you are selling
Wildlife in an attic is not a wood-destroying insect finding and will not appear on an NPMA-33. A home inspector will note it, and buyers react to droppings and chewed wiring more strongly than the repair usually costs.
Your action: deal with it before listing, and keep the invoice describing the exclusion work. What the report does and does not cover →
If you are buying
Attic access is one of the areas a home inspection may or may not reach, and the report will say which.
Your action: read the obstructions section, and if the attic was not entered, ask what it would take to enter it before you remove contingencies.
If you rent
The structure is the landlord's responsibility through the habitability duty under § 55.1-1220, and an animal in the roof is a structural matter rather than a housekeeping one.
Your action: report in writing today, with the dates and times of the noise and any photographs of the exterior. Step by step →
If you are a landlord
Chewed wiring is a fire risk, and exclusion done at the wrong time of year for bats creates a worse problem than the one you started with.
Your action: use an operator holding the VDWR permit, and require the quote to separate removal from the repair of the opening. What you owe →
Before you call: what costs what
An inspection and the work are two separate services with separate prices, and with wildlife there is a third that people never expect: the repair of the way in.
| Typical Virginia range | What it produces | |
|---|---|---|
| Attic and exterior inspection | often free where the company expects to quote the work | a written assessment and entry points |
| Removal or exclusion | quoted per job, driven by the species and the access | the animals out, one-way doors or sealed openings |
| Repair of the entry point | quoted separately, sometimes by a contractor | the reason it does not recur |
| Insulation and clean-up | separate again, where contamination is heavy | a restored attic |
What is usually free: a quote once someone has seen the roofline and the attic.
What is usually not: a written report you intend to give a landlord or a buyer.
Ask which applies before you book, and ask whether the exclusion price includes closing the opening or stops at the animal.
Common misunderstandings
"It's mice, it's always mice." Mice are light and fast. If you can hear weight in it, it is not mice.
"Poison will sort it out." Unlawful for wildlife in Virginia, and for rodents it usually relocates the problem into a wall you cannot open.
"They'll trap it and let it go in the woods." Relocation off the property is not permitted for bats, and wildlife handling generally runs under a permit with conditions on release.
"Seal the hole and they'll leave." They will not. They will die inside or make a new hole, and a mother animal shut away from her young will do remarkable damage getting back.
"Bats can be dealt with any time of year." From May through August young may be present. Excluding then traps them.
"The company is licensed, I checked." Check which licence. The pesticide business licence does not cover wildlife removal.
What to ask before you book
- Do you hold a VDWR commercial nuisance animal permit, and under what name?
- Do you also hold a VDACS pesticide business licence, if rodents are part of this?
- What species do you think it is, and what supports that?
- Does the price include closing the entry point, or is that a separate quote?
- If bats are involved, when will you do the exclusion, and why then?
- What happens to the animals, and under what conditions of your permit?
- Will you provide a written report describing the entry points, separate from the invoice?
The first question is the one that matters most and the one least often asked.
What to have ready before you call
The times and character of the noise over several nights, the age and construction of the house, whether the attic has been entered recently, photographs of the roofline and any disturbed vents or soffits, whether a smell has developed, and whether anyone has already put out poison or bait.
Frequently asked questions
How do I tell a squirrel from a raccoon without looking? Weight and hour. Squirrels are light and active around dawn and dusk; raccoons are heavy and active well into the night.
Is a bat in my house an emergency? Not usually, but if it was in a room with sleeping people or a child, the Virginia Department of Health recommends capturing it for rabies testing rather than releasing it.
Can I do the exclusion myself? The sealing, sometimes. The judgement about whether animals or young remain inside is where self-help goes wrong, and it is the expensive half.
Why did the noise stop on its own? Frequently because young grew and left, or because the animal died inside. If a smell follows within a week or two, it was the second.
Does homeowner's insurance cover this? Policies vary and many exclude damage by rodents and wildlife. Read the exclusions before assuming.
Verify before you pay anyone
Two different credentials, two different registries.
For wildlife — squirrels, raccoons, opossums, bats — ask for the commercial nuisance animal permit issued by the Virginia Department of Wildlife Resources under §§ 29.1-412 and 29.1-417.
For rodents and insects, VDACS publishes an updated list of licensed pesticide businesses weekly, with a public lookup. General pest control is category 7a and wood-destroying pests 7b under 2VAC5-685-70.
Ask which name each is held under. A company doing both work types should be able to answer for both without looking anything up. How to check →
