Small dark specks on bedding come from a short list: bed bug droppings, flea dirt, mould, or something entirely ordinary such as detergent residue or rust from a bed frame. Two simple tests separate them, and both take a minute. Where the specks are concentrated matters as much as what they look like.
This is general information about signs on objects, not medical advice. If you have bites, a rash, or any reaction that concerns you, see a physician. This page identifies what is on your sheets, not what is on your skin.
The two tests
The water test. Touch a damp white cloth to a speck.
- Bed bug droppings smear into a rust-brown or dark blot. They are digested blood and they bleed into the fabric.
- Flea dirt turns distinctly reddish as the dried blood rehydrates.
- Mould, lint, detergent residue do not smear into a blood colour.
The location test. Where the specks concentrate is diagnostic on its own.
- Mattress seams, tufts, the underside of the box spring, near the headboard — bed bugs, which shelter within a few feet of where you sleep.
- Wherever a pet sleeps or rests, carpet, upholstery — fleas.
- Areas that stay damp, near a wall or window, with a musty smell — mould.
What each source looks like
| Source | Appearance | Concentration | Smear test |
|---|---|---|---|
| Bed bug droppings | dark spots or smudges 1–2 mm, sometimes bled into the weave | seams, tufts, headboard, where the body rests | rust-brown |
| Flea dirt | fine specks like ground pepper | pet areas, carpet, upholstery | reddish |
| Mould | irregular, may spread, often with musty smell | damp areas, near walls | no |
| Rust or transfer | uniform, at contact points | zipper, frame, spring | no |
| Everyday sources | isolated, does not recur | random | varies |
Note on colour. Black colour does not identify mould type and does not by itself indicate a more dangerous mould. That is a separate question from pest identification.
Other bed bug signs worth checking
Droppings rarely appear alone. If bed bugs are present, at least one of these is usually findable.
Shed skins. Translucent to light brown, papery, brittle, shaped exactly like a small bed bug. Found along seams, near tufts, close to the headboard. These matter more than droppings — insects shed only while growing, so cast skins indicate a population that is developing rather than a single hitchhiker.
Blood spots. Small smears on sheets or pillowcases, from crushed insects or from bites that continued to bleed.
Live insects. Flat, oval, reddish-brown, roughly apple-seed sized when adult.
Eggs. Pale, about a millimetre, cemented into crevices — usually visible only on close inspection.
What it is not
Bites are not evidence. Reactions to bed bug bites vary enormously between people; some show nothing at all. Bites cannot identify the insect, and a pattern on skin is not a diagnosis. Physical evidence on objects is what an inspector documents.
A single insect is not an infestation, and no insect at all does not rule one out. Early infestations are genuinely hard to find, which is why the shed skins matter — they indicate reproduction rather than arrival.
What to do today
Do not throw the mattress out. It is evidence, disposal often spreads the problem, and encasements are commonly used instead. Decide after an inspection, not before.
Do not spray. Over-the-counter treatment on visible insects scatters the population into surrounding voids and makes professional treatment harder and more expensive.
Photograph what you found, in place, with scale.
Collect a sample if you can — a shed skin or an insect in a sealed bag or between clear tape.
Check the perimeter: seams and tufts of the mattress, the underside of the box spring, the headboard and the wall behind it, and the frame joints.
Note whether anyone else in the building has the same problem. In multifamily housing that is important both for effective treatment and for the argument about origin.
What this means for you specifically
If you own and live in the home
Confirm the identification before spending anything. Treatment for bed bugs is expensive and the wrong treatment is worse than none.
Your action: get an inspection, keep the sample, and do not treat first.
If you rent
The landlord's obligation runs through the duty to keep the premises fit and habitable under Va. Code § 55.1-1220. Your duty under § 55.1-1227 is to notify promptly — and unreasonable delay in reporting shifts the added cost onto you.
Reporting today is both a legal duty and the single strongest thing you can do for your own position.
Your action: notify the landlord in writing, dated, with photographs, and keep a copy. Bed bugs in Virginia rentals → · Step by step →
If you are a landlord
A lease clause assigning pest control to the tenant will not carry the argument. After Parrish v. Vance, decided March 2024, a provision purporting to waive statutory rights is unenforceable.
Your action: arrange a licensed inspection, and give the tenant written notice at least 48 hours before any pesticide application under § 55.1-1223. More →
If you are about to move in
An infestation present at handover is a distinct situation with a short deadline. Under § 55.1-1234.1 a tenant may terminate on written notice within seven days of the date possession was to transfer and recover all deposits and rent paid.
Your action: document immediately and read ending a lease over an infestation before the week runs out.
Before you call: what costs what
An inspection and a treatment are two separate services with separate prices, and conflating them is the most common way people end up surprised by a bill.
| Typical Virginia range | What it produces | |
|---|---|---|
| Wood-destroying insect inspection and report | $65–$200 | the NPMA-33 form |
| General pest inspection | often free where the company expects to quote treatment | a verbal or written assessment |
| Termite treatment | $500–$2,000; more where damage is extensive | a treatment record |
| Structural repair | quoted by a contractor, frequently the largest of the three | an invoice, not a pest control document |
What is usually free: a quote for treatment, once a company has seen the problem.
What is usually not: the inspection report used in a real estate transaction, and any visit that produces a document rather than a price.
Ask which applies before you book. A company quoting one figure covering both inspection and treatment is not quoting what a sales contract or a lender requires.
Common misunderstandings
"No bites, so no bed bugs." Many people show no reaction at all.
"Bites in a line prove it." Skin patterns are not diagnostic. Physical evidence is.
"I should throw out the mattress." Usually unnecessary, often counterproductive, and it destroys the evidence.
"One treatment will fix it." Bed bugs commonly require multiple visits plus thorough preparation.
"Treating my unit is enough." In multifamily buildings, untreated adjacent units are a leading cause of recurrence.
"It's only dirty homes." Bed bugs travel in luggage and used furniture. Housekeeping is not the variable.
What to ask the inspector
- Can you identify this from the specks and skins, or do you need to see the room?
- Is this an early infestation or an established one, and what indicates that?
- Heat or chemical treatment for this situation, and why?
- How many visits will this require, over what period?
- What preparation do you need from me, in writing?
- Should adjacent units be inspected?
- Under what name is your Virginia pesticide business license held?
The second question is worth asking before treatment is priced. Early and established infestations are different jobs.
What to have ready
Property address and whether the building is multifamily, where the specks are concentrated, when you first noticed them, whether you have found skins or insects, whether anyone reports bites, your move-in date, whether neighbours have the same problem, and whether anything has been discarded.
Frequently asked questions
Can flea dirt appear on a bed? Yes, particularly where a pet sleeps. The reddish smear on a damp cloth is the distinguishing test.
What if the specks are only on one side of the bed? Bed bugs concentrate where a body rests. Asymmetry is consistent with them rather than against them.
Are shed skins dangerous? They are not a health hazard in the way bites and allergens are discussed, but they are strong evidence — bag them rather than discarding them.
How much does treatment cost? Bed bug work is among the more expensive pest treatments and frequently exceeds $1,500 for a whole unit, which matters if you are a tenant considering a rent deduction capped at the greater of one month's rent or $1,500. Repair and deduct →
Should I wash everything first? Laundering is usually part of preparation, but do it on the schedule the treating company gives you. Doing it early and then sleeping in the room can undo it.
Verify before you pay anyone
VDACS maintains a public pesticide search at pesticidesearch.vdacs.virginia.gov and publishes an updated list of licensed pesticide businesses weekly. General pest control is category 7a under 2VAC5-685-70.
Ask which name the license is held under — this matters especially if the receipt will support a rent deduction. How to check →
