Waking up with itchy bites but not seeing any insects can be frustrating and concerning. Many homeowners in Columbia, Ellicott City, and throughout Maryland experience bites overnight without knowing what pest is responsible.

Several insects bite while people sleep, including bed bugs, fleas, mosquitoes, mites, and even carpet beetle larvae. Identifying the source of these bites is the first step toward eliminating the problem.

1. Bed Bugs

Bed bugs are one of the most common pests responsible for bites at night.

Signs of bed bugs include:

• bites in clusters or lines
• small blood spots on sheets
• dark stains on mattress seams
• tiny reddish-brown insects hiding in cracks

Bed bugs hide during the day and feed on human blood at night.

2. Fleas

Fleas can also bite humans at night, especially if pets are present.

Common flea bite signs:

• bites around ankles and legs
• extremely itchy red bumps
• pets scratching frequently

Fleas can live in carpets, bedding, and furniture.

3. Mosquitoes

If a mosquito enters the home, it may bite during the night while people sleep.

Mosquito bites typically appear as single itchy welts on exposed skin.

4. Mites

Certain mites can bite humans when their normal hosts are unavailable.

Examples include:

• bird mites
• rodent mites
• straw itch mites

Mites are extremely small and often invisible to the naked eye.

5. Carpet Beetle Larvae

Carpet beetle larvae don’t bite, but their tiny hairs can irritate skin and cause reactions that resemble bites.

Signs include:

• small red itchy bumps
• tiny shed skins in closets
• damage to fabrics

6. No-See-Ums (Biting Midges)

These tiny insects are almost invisible but can cause extremely itchy bites.

They are more common in humid areas and near water sources.

Why You May Not See the Bugs

Many pests that bite at night are:

• extremely small
• active only in darkness
• hiding in mattresses, carpets, or wall voids

This is why bites often appear before the insects are discovered.

What To Do If You’re Getting Bitten At Night

If you suspect insects are biting you while sleeping:

• inspect mattresses and bedding
• wash bedding in hot water
• vacuum carpets and furniture
• check pets for fleas

If bites continue, a professional pest inspection may be needed to identify the source.
