How do you identify this pest?
What does it look like?
Adults are about 3/16 inch long, similar in shape to an apple seed
Reddish brown, with an oval, flat body
Which features set it apart?
- Wingless, flat and oval
- Young bed bugs are pale and hard to see until they have fed
- Eggs are tiny, about 1 mm
What is this pest often mistaken for?
- Carpet beetles, spider beetles and young cockroaches
- Carpet beetle larvae are covered in short, stiff hairs. Bed bugs are smooth and flat
- Bed bugs cannot fly or jump
- When in doubt, save a specimen for a pro to identify
What are the signs of an infestation?
- Stains: Rusty or reddish stains on sheets or mattresses from bed bugs being crushed. EPA: How to Find Bed Bugs
- Droppings: Dark spots that may bleed into the fabric like a marker would. About the size of a printed dot, along mattress piping, seams and tags, and in bed frame cracks. EPA: How to Find Bed Bugs
- Eggs and shed skins: Tiny eggs and pale yellow skins that young bed bugs shed as they grow. Eggs are about 1 mm, in seams, cushion folds, drawer joints and near outlets. EPA: How to Find Bed Bugs
- Smell: A buggy smell is often mentioned, but it is seldom noticeable except in extreme infestations and should not be relied on. No smell does not mean no bed bugs. University of Kentucky Entomology ENTFACT-636
What damage does it do to a home?
- Bed bugs do not damage the house. The harm is bites, lost sleep and worry, and most furniture and bedding can be treated rather than thrown out. EPA: Do-it-yourself Bed Bug Control
When is this pest active?
Pest activity follows the weather, so timing matters. Treating inside the active window is usually cheaper and more effective than waiting for the problem to grow.

What do bites and stings from this pest look like?
What can a bite tell you, and what can it not?
Bites from different insects often look alike. The same insect can cause very different reactions in different people, and many people never react at all. A bite cannot identify a species.
This is general information, not medical advice. If you are worried about a bite or a reaction, see a doctor.
What a bite can and cannot tell you: a bite cannot identify the insect that caused it. Bed bug bites are not reliably distinguishable from flea bites, mosquito bites or several skin conditions, so a mark on your skin is not evidence of bed bugs. Only physical evidence confirms bed bugs: live insects, shed skins, eggs, or dark spotting along mattress seams.
What people report: reactions vary widely. Some people get small itchy red bumps, and many people show no reaction at all, with estimates ranging from about 30% to about 70% depending on the study. Marks may take up to 14 days to appear, and marks that are not scratched usually clear within about a week.
Get medical advice if:
- Redness or swelling spreads, or the area becomes warm and painful
- You have a fever
- You have trouble breathing, or swelling of the face or throat, which needs emergency care
- A mark gets worse after several days instead of better
This is general information, not medical advice, and it cannot be used to diagnose anything. PestChief does not diagnose bites and does not provide medical care. If a bite or skin reaction worries you, contact a licensed healthcare professional.
What should you do right now?
These are steps a homeowner can take today, before anyone visits. None of them replace a licensed local company once an infestation is established.
- Check mattress piping, seams and tags, bed frame cracks, and nearby furniture seams and cushion folds. EPA: How to Find Bed Bugs
- Do not throw out your mattress. Most items can be treated, and encasements can cover mattresses and box springs. EPA: Do-it-yourself Bed Bug Control
- Do not move items from the affected room into rooms without bed bugs. EPA: Top Ten Tips to Prevent or Control Bed Bugs
Want a local company to handle Bed bugs?
PestChief is free to the homeowner. Your request goes to one independent local pest control company that covers your ZIP code and handles that pest, not to seven. That company contacts you directly to confirm details and arrange a visit.
What does treatment typically cost?
What you pay depends on the pest, the size of the property and how far the problem has spread.
These are national estimates drawn from published industry sources, not PestChief quotes. Every figure states the basis it is measured on. The real price comes from the company that inspects your home.
When should you call a pest control company?
Call when the job has outgrown a homeowner fix. The usual signs are damage to wood, wiring or insulation, activity that returns within weeks of treating it, a nest or colony you cannot reach safely, and any pest that bites or stings people living in the home. Specialty pests need specific state licensing to treat, so the work has to go to a licensed company.
PestChief does not spray, trap or treat pests. Give your ZIP code and the pest you are seeing, and PestChief passes the request to one independent local pest control company that covers your address and handles that pest. That company contacts you directly to confirm details and arrange a visit. The service is free to the homeowner, and the company sets its own price.
How do I know it is bed bugs and not something else?
Bites alone are not proof. People react very differently to bed bug bites, and flea bites, mosquito bites and skin conditions are all mistaken for them. What confirms bed bugs is physical evidence: live insects about the size and shape of an apple seed, pale shed skins, dark digested-blood spots that look like felt pen dots, and small rust-colored smears on sheets.
Check the seams and piping of the mattress, the crevices of the box spring frame, the headboard where it meets the wall, and the seams of upholstered chairs beside the bed.
| Bed bugs | Fleas | |
|---|---|---|
| Where you find them | Mattress seams, box spring, headboard, bed frame joints | Pet bedding, carpet, upholstery, on the animal |
| Appearance | Apple-seed size, flat, reddish brown, no jumping | Tiny, dark, laterally flat, jumps strongly |
| Bite marks | Appearance varies between people and cannot confirm bed bugs | Appearance varies between people and cannot confirm fleas |
| Other evidence | Dark spotting on sheets, shed skins, sweet musty odor in heavy cases | Black specks of flea dirt in pet bedding |
| Treatment path | Room-level heat or a multi-visit chemical program | Pet treatment plus indoor treatment and growth regulator |
Heat treatment or chemical treatment?
Both can work when done properly, and the right choice depends on the building, the level of infestation and your budget and timeline.
| Whole-room heat | Chemical program | Combination | |
|---|---|---|---|
| How it works | Room air raised to a lethal temperature and held there | Residual and contact products applied to harborage across several visits | Heat on the worst rooms plus chemical support around them |
| Visits needed | Often one, plus a follow-up inspection | Typically two to four visits spaced two weeks apart | Usually two to three |
| Preparation | Heavy: remove heat-sensitive items, follow a detailed list | Moderate: launder, bag, declutter, access all walls | Moderate to heavy |
| Typical relative cost | Higher | Lower | Middle to higher |
| Residual protection | None after cooling; relies on completeness | Residual products keep working between visits | Both |
What does professional bed bug work involve?
- A room-by-room inspection of beds, furniture, baseboards and adjacent rooms
- A written treatment plan and a preparation list you complete before the visit
- Vacuuming and steam on accessible harborage
- Mattress and box spring encasements to trap and expose remaining bugs
- Heat or a sequence of chemical applications, or both
- Interceptors under bed and sofa legs to monitor results
- A follow-up inspection two to four weeks later to confirm elimination
What should I do right now?
The instinct to throw out the mattress and move to the sofa makes things worse, because it spreads bugs to a new room and leaves the original harborage untouched. Keep sleeping in the same bed, keep it away from the wall, and keep bedding off the floor until the technician has inspected.
A note on coverage for bed bug work
Bed bug treatment, particularly heat treatment, requires specialized equipment and training, so not every company offers it. Coverage is narrower than for general pests, and matching can take longer in smaller markets. PestChief would rather wait for a company that actually does this work than pass your request to a generalist.
Frequently asked questions
How much does bed bug treatment cost?
Chemical treatment commonly runs $400 to $900 per room nationally across multiple visits. Whole-home heat treatment commonly runs $1,200 to $3,000 or more. The inspecting company quotes based on rooms affected and method.
How long does it take to get rid of bed bugs?
Heat treatment can kill all life stages in a single session, with a follow-up inspection two to four weeks later. Chemical programs typically take four to eight weeks across two to four visits.
Can I get rid of bed bugs myself?
Full elimination without professional help is uncommon. Laundering, encasements, vacuuming and interceptors genuinely help and are recommended by the EPA as part of a plan, but they are supporting measures rather than a substitute for treatment.
Do bed bugs mean my home is dirty?
No. Bed bugs travel in luggage, second-hand furniture, backpacks and between apartment units. They are a hitchhiking problem, not a hygiene problem, and clutter only matters because it gives them places to hide.
Should I throw away my mattress?
Usually not. An encasement traps bugs inside and lets treatment work. Discarding a mattress risks spreading bugs through the building and the money is generally better spent on treatment.
Do bed bugs spread disease?
Bed bugs are not established as disease vectors. The documented harms are itching, secondary skin infection from scratching, sleep disruption and significant stress, which is reason enough to treat promptly.
Will one treatment be enough?
Sometimes with heat, rarely with chemicals alone. Eggs and bugs sheltered in deep harborage are why follow-up visits and monitoring with interceptors are part of a credible treatment plan.
I live in an apartment. Does that change anything?
Yes. Bed bugs move between units, so treating one apartment in isolation often fails. Notify your landlord or property manager, since coordinated treatment of adjacent units is usually necessary and is the landlord's responsibility in many jurisdictions.
