You don't actually have to see them first
By the time most people spot a live bed bug in their mattress, the infestation is already a few weeks old. The earliest signs are smaller and easier to miss — but if you know what to look for, you can catch a bed bug problem before it spreads to your couch, your office chair, and your guest room.
The five earliest signs
1. Bites in a straight line of three
Bed bug bites cluster — usually three in a row, sometimes called the "breakfast, lunch, and dinner" pattern. They itch worse than mosquito bites and last longer. If you're waking up with new bites every morning, look closer at your mattress.
2. Tiny rust-colored spots on sheets
These are digested blood spots from when bed bugs feed and walk away. They're about the size of a period at the end of a sentence. Look at the corners of your mattress and along the box spring seams.
3. Pale yellow eggshells the size of a poppy seed
Look in mattress seams, along the back of the headboard, behind picture frames near the bed, and inside outlet covers within 6 feet of the bed.
4. A faint sweet, musty smell
Only present in moderate-to-heavy infestations. Often described as smelling like wet towels left in a gym bag.
5. Tiny live bugs in seams
Adults are about the size of an apple seed and a reddish-brown. They hide in dark, tight spaces during the day.
What people mistake for bed bugs
| Looks like a bed bug | What it actually is |
|---|---|
| Small reddish-brown insect on a windowsill | Carpet beetle (harmless to you, but eats fabric) |
| Tiny black bug in basement | Cellar spider babies or springtails |
| Bites with no clear pattern | Likely fleas (especially if you have pets) |
| Single welt on your arm | More likely mosquito or spider |
What to do if you think you have them
1. Don't bomb the room. Foggers scatter bed bugs deeper into walls. 2. Don't throw out your mattress. A good encasement plus proper treatment saves almost every mattress we see. 3. Stop sleeping in another room. That just spreads them. 4. Get a discreet inspection. We use unmarked vehicles. None of your neighbors will know.
