Identify a pest or pest sign from a photo

You get a careful best guess and a clear next step.

Drag & drop a photo here

or use the buttons below. A close, well-lit shot of the pest, plant damage, droppings, nest, or product damage works best.

Include the setting, location, size, host plant or product, and what changed.

AI guidance can be wrong and is not a pest inspection, plant diagnosis, or medical advice. PestPin does not store the photo. Your browser removes metadata and sends the resized image to our image-analysis service with zero-data-retention and provider data collection disabled. Do not upload people, skin, injuries, or bites. Suspected venom exposure? Call Poison Control 1-800-222-1222. Seek medical care for symptoms and call 911 for an emergency.

Quick answer

A clear photo of the bug, or of what it left behind (droppings, chewed wood, webbing in the pantry, a nest), usually narrows it to a family of pests. The questions add where you are and what kind of place it is. Neither is a diagnosis. When the picture is unclear, when it is a bite or a rash, a honeybee swarm, or a farm or wildlife matter, we point you to the right specialist instead of a pest control company.

How to tell what you're dealing with

No bug expertise needed. These are things anyone can notice, and they're the same clues the tool uses.

  1. Notice where and when you saw it

    The room, and whether it showed up during the day or at night, is usually the biggest clue. Kitchens, bathrooms, beds, attics, and woodwork each point to different pests.

  2. Look at what it left behind

    This is often more useful than the bug itself: droppings, dark spotting or shed skins in furniture seams, shed wings by a window, sawdust, mud tubes on the foundation, or a nest. A bite pattern alone cannot name a pest.

  3. Get a rough size

    Compare it to something everyday, like a sesame seed, a grain of rice, a coin, or bigger. You do not need to be exact.

  4. Notice how it moved

    Whether it flew, crawled, or jumped narrows things down quickly.

  5. Match it with the tool above

    Feed those clues into the photo tool or the quick questions to narrow a broad category and see who may be able to help. The result can be wrong and is not an on-site identification.

One tool, different kinds of help

The same bug in a kitchen, a barn, a lawn, a warehouse or an attic can call for a different license and different experience. So the tool decides who should help separately from its guess at what the bug is. We offer to send a request only where our license records can back it up; for everything else we say what to check before you hire anyone.

Pest control for homes and apartments

Homes, apartments, rentals, and multifamily properties

Pick the pest below and we narrow down the kind of visit to ask for.

Check: Check that the company works on your kind of property and holds the license your state requires for that work.

Wildlife removal

Rodents, bats, birds, snakes, raccoons, squirrels, and similar animals

Rules, seasons and permits for animals differ by state and by species. Getting an animal out and sealing it out is different work from treating insects.

Check: A pest control license does not show wildlife experience. Ask what permits your state requires for that animal and whether the company has done this work before.

Lawn, garden and tree problems

Lawns, gardens, trees, greenhouse plants, and ornamental landscapes

Damage to plants can come from insects, disease, watering, soil or weather, and a photo alone often cannot tell them apart. Our records do not show who does lawn or plant work.

Check: Start with a local plant clinic or your county Extension office, or a company whose lawn or plant license you can check.

Bugs in stored food

Homes, warehouses, mills, food storage, and packaged dry goods

Which package or product it came in matters as much as the bug. Set the affected food apart and check the packages next to it.

Check: Our records do not show who handles pests in stored food. Ask about that experience, and about food-business work if this is a business, before you hire.

Termites and other wood-destroying insects

Termites, carpenter ants, wood-boring beetles, and unexplained wood damage

Different wood pests need different treatment. Keep a sample or the shed wings, and leave the damage as it is until someone has inspected it.

Check: Ask for the termite or wood-destroying insect credential your state requires, especially if you need a report for a home sale.

Mosquitoes, ticks and fleas

Mosquitoes, ticks, fleas, biting flies, and problems affecting a whole neighborhood

A pest company can treat your property. If people are getting sick, or the problem covers a whole neighborhood, your local health department is the right call too.

Check: Our records do not show who does mosquito or tick work. Ask the company whether it is licensed for it, and see a doctor about any symptoms.

Businesses, restaurants and food facilities

Restaurants, hotels, healthcare, schools, offices, warehouses, and manufacturing

A business usually needs a written program: regular inspections, monitoring, and records that hold up in a health inspection or an audit.

Check: Our records do not show who does commercial or food-facility work. Ask for that experience, the paperwork they provide, their insurance, and how fast they come back when you call.

Farms, crops and public land

Crops, livestock, nurseries, rights-of-way, public land, and regulated invasive species

What to do about a crop pest or a regulated species depends on the plant, the county, the season, and state or federal rules. A home pest company is not the right default.

Check: Start with your county Extension office or the agriculture, wildlife or health agency responsible, and use a licensed commercial applicator if they advise one.

Outside pest matching: Photos of skin, bites, rashes, or injuries go to medical or veterinary care. Possible honeybee swarms go to a beekeeper or pollinator specialist. A clear non-pest subject does not receive a pest-control call to action.

    Most likely: Drain flies or a cockroach

    How to tell: Fuzzy, moth-like flies at the sink, or a flat insect that darts from the light

  • On the bed or mattress seams

    Most likely: Bed bugs

    How to tell: Small reddish-brown ovals, plus little dark spots on the sheets

  • Around ankles or on carpet

    Most likely: Fleas

    How to tell: Tiny dark specks that jump, and itchy bites low on the legs

  • Damp basements or under sinks

    Most likely: Silverfish or springtails

    How to tell: A wingless, silver, teardrop insect that darts, or specks that hop near moisture

Look-alikes people mix up

The pairs that get confused most, and the one thing that tells them apart, starting with the one that matters.

Flying ant or termite swarmer?

This one is worth getting right. A pile of discarded wings indoors, mud tubes, or hollow-sounding wood means treat it as a possible termite and get an inspection. Winged ants at a light can come from an outdoor swarm or an indoor nest, so identify the insect and inspect the site before dismissing it.

Full comparison

Bed bug or flea?

Bites alone cannot distinguish them. Bed bugs leave insects, dark spotting, pale eggs, or shed skins in furniture seams. Fleas are tiny insects that jump and are often found near animal resting areas.

Evidence comparison

Cockroach or beetle?

A cockroach is a flat, fast bug that scatters from the light, and many so-called water bugs are just big roaches. A beetle has a hard, rounded shell and moves slower.

Cockroach guide

Carpenter ant or termite?

Carpenter ants are larger dark ants that push out little piles of sawdust. Termites eat the wood itself and leave mud tubes. Both damage wood, so confirm with a pro.

How to photograph a bug so it can be identified

A clear photo is useful evidence to preserve for an inspector or an identification service.

  1. Fill the frame

    Get as close as your camera can still focus so the bug is not a tiny dot, and crop out the clutter around it.

  2. Use good light

    Natural light or a bright lamp works best. Avoid deep shadow and harsh flash glare.

  3. Hold steady and tap to focus

    A sharp, in-focus photo beats a zoomed-in blurry one every time.

  4. Add something for scale

    A coin or small ruler beside the subject shows how big it really is. Do not place a hand near an unknown pest.

  5. Photograph the signs too

    If you cannot get the bug itself, take a picture of what it left: droppings, mud tubes, shed wings, or damage.

Pest identification: frequently asked questions

How can I identify a bug in my house?

Start with what you can actually see: where it appeared, when activity occurs, and evidence such as an insect, droppings, shed wings, a nest, product webbing, or damage. Then use a clear photo or the quick questions. The tool narrows a broad category and next step, but it can be wrong and does not replace an on-site or lab identification.

What is this tiny black bug in my kitchen?

Tiny bugs following a line along a kitchen counter may be ants heading to food. A flat, fast bug that scatters when the light comes on may be a cockroach. Beetles or larvae inside flour, cereal, or spices suggest a stored-product pest. A clear photo plus the exact location can narrow the category, but an on-site check may still be needed.

How do I tell a bed bug from a flea?

Bites alone cannot identify either pest. Look for a flat reddish-brown bug, dark spotting, eggs, or shed skins in mattress and furniture seams for bed bugs. Fleas are tiny jumping insects often found near animal resting areas. A collected insect or clear site evidence matters more than the shape or location of a bite.

Is it a termite or a flying ant?

Shed wings alone can come from either one. What points to termites is the setting: a small pile of discarded wings by a window or door, mud tubes on the foundation, or wood that sounds hollow when you tap it. Flying ants around a light are usually just a nuisance. Save a few of the insects in a bag and arrange a wood-destroying insect inspection rather than treating from a photo alone.

What bug bites me at night?

A bite pattern cannot reliably name the pest. Bed bugs, fleas, mosquitoes, mites, skin conditions, and other causes can look alike. Look for an actual insect or site evidence away from skin. Use a clinician for symptoms, Poison Control for suspected venom exposure, and the pest identifier only for a pest or pest sign.

Should I identify the pest myself or call a professional?

Getting close on your own helps you act faster and know what to ask. A licensed inspector can examine the site and may confirm the exact pest, which matters most for termites, bed bugs, rodents, and any spider you think could be a recluse or widow. This tool is a guide, not a diagnosis.

What are these tiny bugs in my bathroom?

Small fuzzy, moth-like flies near a sink or shower drain are often drain flies, which breed in wet organic buildup. A fast, flat insect that darts from the light may be a cockroach. A wingless, silver, teardrop-shaped insect may be a silverfish. Cleaning the actual breeding source can control drain flies, but check other wet sources if activity continues; a recurring roach problem is worth a professional inspection.

How accurate is a photo bug identifier?

Results vary with focus, scale, lighting, life stage, and whether the key feature is visible. A clear photo can narrow a broad category, but it may still be wrong and should not replace an inspection, lab identification, plant clinic, or medical advice. The tool can return an uncertain result or ask for a clearer photo, and it never uses a skin mark to identify a pest.

Can I identify a spider from a photo?

A photo may narrow the subject to a spider and show useful features, but do not rely on it to decide that an unknown spider is harmless. Medically serious spiders can resemble common species. If there is any chance it is a recluse or widow, or someone was bitten, keep your distance and seek professional guidance. For suspected venom exposure, call Poison Control at 1-800-222-1222 or seek medical care.
