Bug identifier with a safety check
What kinda bug is this? Identify a bug or spider from a photo
What kinda bug is this, and is it dangerous? Upload one photo: the bug identifier names the insect or spider, says whether it bites, stings or infests a home, and what to do next.
The result
What the bug identifier tells you
One photo, one report. Artificial intelligence analyzes the shape, color and marks in your photo; the report starts with the name and goes on to what to do next.
The insect or spider, with how sure the match is, and the features in your photo that point to it.
The bugs it is often mistaken for, such as a brown recluse and a cellar spider, and the detail that tells them apart.
One plain call, with the reason. Never a promise that a bug is harmless.
- Low concern
- Caution
- Urgent
Whether it bites or stings people or pets, and whether one in the house can mean more.
How to remove or contain it safely, what to clean, and when a pest control pro is worth the call.
A short checklist for the room you found it in, so fewer bugs come back.
Method
How the bug identifier by photo works
- 01
Capture a clear photo
From a safe distance, on a plain surface if you can, with the body and legs in focus. Never pick up a spider to photograph it.
- 02
Say where you found it
The room and the town or state. A brown recluse or a bed bug means something different in a bedroom in Missouri than on a porch in Maine.
- 03
Get the name and the look-alikes
The bug identifier names the insect or spider, says how sure the match is, and lists the look-alikes to rule out with what tells them apart.
- 04
Read the safety check
A plain level of concern, whether it bites, stings or infests homes, how to remove or contain it, and when to call a pest control pro.
Photos
How to take a bug photo for identification
A phone camera is enough. Keep your distance: a sharp photo from a little further away beats a blurry close-up.
Do
From above, in focus
The whole body and all the legs in the frame. Tap the bug on screen so the camera focuses on it, not the floor.
Good light, no flash glare
Daylight or a bright room. Flash can wash out colours and the marks you need.
Something for scale
A coin or a ruler beside it, not touching it, tells the size of the body.
Show the key detail
For a spider, the eyes and the front body section; for a bed bug suspect, the flat body. If the photo misses it, retake it and run it again.
Don't
Do not handle it
Never pick up a spider, bee or wasp for a photo, and do not try to trap one that may be a recluse, a widow, a bee or a wasp: photograph it where it is.
No squashed bugs
A crushed bug loses its shape and marks. If it is dead already, photograph it as it lies.
Not through a curved jar wall
Curved glass blurs and bends the marks. If the bug is already in a closed jar, keep it closed and shoot through the flat lid or base.
Bitten or stung and feeling unwell?
Do not wait for any bug identification. A severe allergic reaction to a sting, such as trouble breathing or a swelling face or throat, can be life-threatening and needs emergency care now. In the US, the Poison Help line, 1-800-222-1222, gives expert advice at no cost, day and night.

How to identify a brown recluse spider
The violin mark is the famous clue, but it is not the one to trust. Check these together, from a sharp photo: zoom in rather than move closer.
Most spiders have eight eyes. Recluse spiders have six, in pairs: one pair in the middle and one at each side. Only a few other spiders share this pattern.
A dark violin shape on the front body section, neck pointing to the rear, gives the nickname fiddleback. Cellar spiders and pirate spiders can carry a similar mark.
No obvious stripes, bands or spots on the abdomen or the legs, and the legs have no spines.
Usually light to medium brown, though some range from whitish to dark brown; the body is usually about 6 to 20 mm.
Its documented range lies roughly south of a line from southeastern Nebraska through southern Iowa, Illinois and Indiana to southwestern Ohio, and from central Texas to western Georgia.
Spiders sent in as brown recluses from outside that range were rarely recluses: misidentification is common, even by non-experts in authority.

What type of spider is this? How a black widow looks
Widow spiders are a group of species. Look at the underside if the spider sits upside down in its web.
- Female
- Shiny black or dark brown when full grown, usually with a red or orange hourglass on the underside of the abdomen; some have a pair of red spots or no mark at all.
- Male and young
- Often red, or red and white, marks on the upper side of the abdomen: stripes, bars or spots.
- Which bite matters
- Only the bites of females are dangerous to people. A bite can bring severe muscle pain, abdominal cramps and sweating: see a doctor.
- North America
- The southern, western and northern black widow, the red widow and the brown widow.

Is this a bed bug? Signs to check
One bug is a clue, not a verdict. The US EPA calls bites a poor indicator: they look like mosquito bites, rashes or hives, and some people do not react at all.
Light brown to reddish-brown, flat and oval, with no hind wings, about 4 to 5 mm long. Young ones are pale and turn browner as they moult.
Booklice, small cockroaches and carpet beetles. Bat bugs look so much like bed bugs that a microscope is needed to tell them apart.
Rusty or reddish stains on sheets or the mattress, and dark spots of droppings that bleed into the fabric like a marker.
Tiny eggs, about 1 mm, and the pale yellow skins young bed bugs shed as they grow.
Mattress and box spring seams, piping and tags, cracks in the bed frame and headboard. A crack that holds a credit card can hide one.

Bug and spider identifier: common house bugs and what sets them apart
The bug finder starts from questions like these. A clear photo of the body and the legs answers most of them.
- Wolf spider
A hunter that lives alone and usually spins no web; two of its eight eyes are large and prominent, and the female carries her egg sac at the end of her body.
- Cellar spider
Very long, thin legs and an often whitish or grey body; also called daddy long-legs, a name shared with harvestmen and crane flies.
- Silverfish
A small wingless insect, silvery grey, about 7 to 10 mm, that moves with a fish-like wiggle and lives in damp places: bathtubs, basements, kitchens.
- Cockroach
About 30 of the known cockroach species live alongside people, and some are well-known pests; most species are small and inoffensive.
- Honey bee
Its barbed sting lodges in skin and tears loose. Bumblebees and many solitary bees have smoother stings and can sting again.
- Wasps
Yellow jackets and some other wasps have only small barbs on the sting.

Scope
What a bug identification from a photo can and cannot settle
A photo can show
- The name of a common insect or spider, with how sure the match is
- Look-alikes to rule out, and the details that tell them apart
- Whether that kind of bug bites, stings or infests homes
- What to do next: remove it, watch for more, or call a pro
Only an expert with it in hand can tell
- Whether a bite or a rash on your skin came from a bug: ask a doctor
- Any promise that a bug or spider is harmless to touch
- How far an infestation has spread: only an inspection shows that
- Bat bugs from bed bugs for certain: that takes a microscope
A name is the start. The bug identifier also says how much concern it calls for, whether it bites, stings or spreads in a home, and when to call a pro.
Next
After the bug identification: what to do
- 01
Keep your distance, do not squash it
Photograph it where it is and keep children and pets away. A whole bug is easier to identify again, for you or a pest control pro.
- 02
Look for more signs
One bed bug or roach is a clue. Check seams, cracks and dark corners nearby for droppings, eggs and shed skins before you treat.
- 03
Found a bed bug?
Check the bed first: mattress seams, piping, tags and the frame. The US EPA lists the signs and the hiding places.

Bitten or stung?
Call your doctor, or in the US the Poison Help line, 1-800-222-1222. Keep the bug or its photo to show them.
America's Poison Centers - 05
When to call a pro
Suspected bed bugs, termites, a wasp nest in the house, or bugs that keep coming back after cleaning: a licensed pest control professional inspects in person.

Limits
What a bug identifier cannot promise
A photo cannot decide that a bug or spider is safe to touch or that a bite is harmless. The report is not medical advice and not a pest inspection: for a bite or sting see a doctor or call poison control, and for an infestation call a licensed pest control professional.
FAQ
Bug identifier: frequently asked questions
Can I take a picture of a bug and you tell me what it is?
Yes. Upload one clear photo from above and the bug identifier names the insect or spider, with the look-alikes to rule out and what to do next.
How can I tell what kind of bug I found?
Count the legs first: insects such as ants, beetles and butterflies have three pairs, while adult spiders, ticks and mites have eight legs. Then the body shape, the wings, the color and the marks. A photo with something for scale and the place you found it narrows it down.
What type of spider is this?
Upload a photo where the spider fills the frame. The spider identifier names it, lists the look-alikes, and says whether it is one of the few North American spiders with dangerous venom: the brown recluse and the widows.
What does a brown recluse spider look like?
Usually light to medium brown, with a dark violin shape on the front body section and plain legs without spines. The surest sign is six eyes in three pairs; the violin alone is not proof, since cellar spiders and pirate spiders can have one too.
What does a black widow spider look like?
The female is shiny black or dark brown, usually with a red or orange hourglass on the underside of the abdomen. Males and young ones often have red, or red and white, marks on the upper side. Only the female's bite is dangerous to people.
Spider identification in Michigan: which spiders should I watch for?
Michigan lies north of the brown recluse's documented range, which runs roughly south of a line from Nebraska to southwestern Ohio. The northern black widow does occur in Michigan, though its main range is the Middle Atlantic states. Add your town to the form and the report takes the place into account.
Is this a bed bug, or something else?
An adult bed bug is flat, oval, reddish-brown and about 4 to 5 mm long, with no hind wings. Carpet beetles, booklice and small cockroaches get mistaken for one, and a bat bug can only be told apart under a microscope.
What could be mistaken for bed bugs?
Carpet beetles, booklice, small cockroaches and bat bugs. Bites are a poor guide too: they look like mosquito or chigger bites, rashes or hives. Look for stains, droppings, eggs and shed skins instead.
How does bed bug identification work from a photo?
The bug identifier checks the shape, the colour and the size against bed bugs and their look-alikes. If it points to bed bugs, the report lists the signs to look for in the bed and when to call a pro.
What kills bed bugs instantly?
No single step clears an infestation. Treatments include heating the room, vacuuming, hot washes and pesticides, and repeated treatment may be needed; it is hardest in apartment buildings. A licensed pest control pro can plan it.
How do you get rid of bugs in the house?
Start with the name, since a silverfish, a roach and a bed bug need different steps. The report says how to remove or contain the bug, what to clean, how to keep more out, and when to call a pro.
What is the fastest way to tell if a bug is dangerous?
Get a clear photo from a distance and do not touch it. The bug identifier gives a level of concern with the reason. If someone was bitten or stung and feels unwell, call a doctor or poison control first.
Are all indoor insects harmful to human health?
No. Of the many cockroach species, for one, only a few dozen live alongside people. A few house bugs bite, sting or spread through a home. The report says which kind you have; it never promises that a bug is harmless to touch.
How do wasp stings differ from bee stings?
A honey bee's barbed sting lodges in the skin and tears loose. Wasps such as yellow jackets have only small barbs. Either sting can cause a serious allergic reaction: trouble breathing or a swelling face needs emergency care.
Can Google identify a bug?
Photo searches such as Google Lens can suggest a name from a picture. The bug identifier gives the name too, then the look-alikes, a level of concern and what to do next in your home.
Is there a free website that can identify insects?
This bug identifier runs online in your browser like an app, on a phone or a computer, with no apps to install. Trying the form is free and needs no card, no account and no trial.
Is this bug identifier really free?
Trying the form here is free. Nothing starts billing and there is nothing to cancel.
Can I trust the results from the bug identifier?
Treat the name as a strong lead, not a final word. Every report shows how sure the match is and the look-alikes. When the stakes are high, such as a suspected recluse or bed bugs, confirm it with a pro or your local extension office.
What happens if the bug identifier gives the wrong answer?
Each report names the look-alikes and what tells them apart, so you can check the bug against them. If a key detail is missing, retake the photo and run it again; when a bite is involved, see a doctor whatever the name.
Can it identify a bug bite?
No. A bite or a rash on skin does not show which bug caused it, and it needs a doctor. The bug identifier works from a photo of the bug itself.
Found a bug or spider you do not recognise?
Take one clear photo from a safe distance and see what kind of bug it is and what to do next.
