Bed bugs are experts at hiding. By the time most people realize they have an infestation, it has already spread well beyond the mattress. Knowing the early warning signs means you can act fast before a small problem becomes a serious one.
1. Unexplained Bites on Your Skin
The most common first sign is waking up with small, itchy red welts usually in a line or cluster on your arms, neck, or shoulders. Bed bugs feed at night while you sleep. Not everyone reacts to bites, so the absence of bites does not mean you are clear.
2. Tiny Dark Spots on Your Mattress or Sheets
Bed bugs leave behind small dark brown or rust-coloured spots of excrement on mattress seams, sheets, and nearby walls. These spots are about the size of a period at the end of a sentence. Run a damp cloth over suspicious marks if they smear rusty red, that is a strong indicator.
3. Blood Stains on Your Pillowcase
When a feeding bed bug is accidentally crushed, it leaves a small blood smear. These appear as tiny reddish streaks on pillow cases and sheets. Many people initially mistake these for small cuts.

4. Shed Skins
Bed bugs shed their outer shell five times as they grow. These translucent, hollow casings are left behind in hiding spots mattress seams, box spring folds, behind headboards, and in electrical outlets. Finding shed skins is one of the most reliable confirmation signs.
5. A Sweet, Musty Odour
A significant bed bug infestation produces a distinct sweet, musty smell, sometimes described as overripe berries or almonds. This odour comes from the bugs' scent glands. If a room has an unexplained smell and you have other signs present, take it seriously.
6. Live Bugs in the Seams
Adult bed bugs are visible to the naked eye, about 5mm long, flat, oval, and reddish-brown. Check the seams and tags of your mattress and box spring, the folds of your bed frame, behind the headboard, and inside nightstands. Use a flashlight and a credit card to run along seams to disturb hiding bugs.
7. Eggs and Tiny White Dots
Bed bug eggs are about 1mm long, pearlescent white, and sticky. They are laid in clusters in hidden crevices. Given that a single female can lay 1-5 eggs per day and up to 500 in her lifetime, early discovery matters enormously.
What to Do If You Spot These Signs
Do not attempt to treat a bed bug infestation yourself. Over-the-counter sprays are largely ineffective against eggs and hidden populations, and improper treatment can cause bugs to scatter to other rooms, making the problem significantly worse.

Bed bugs can live for months without feeding, which is why they often survive in unused rooms, storage units, and secondhand furniture. If you have recently brought used furniture into your home or stayed in a hotel, these are risk factors worth noting.
