How to See Bed Bugs During the Day: A Homeowner’s Guide

Bed bugs have a reputation for being elusive, mostly coming out at night when people are asleep. But if you think you have bed bugs, you don’t have to wait until dark to confirm it. With the right approach, you can spot bed bugs during the day—even though they prefer to stay hidden.

Knowing where bed bugs hide during the day and how to properly inspect your home can help you catch an infestation early. Here’s what to look for and how to increase your chances of seeing them in the daylight.

Do Bed Bugs Come Out During the Day?

Bed bugs are nocturnal by nature, meaning they’re most active at night. But that doesn’t mean they never appear during the day. In some cases, they’ll come out if:

• They haven’t fed in a while and need to find a host.
• Their usual hiding spots have been disturbed (such as after cleaning or moving furniture).
• The infestation is large, forcing them to spread into more exposed areas.
• They detect body heat or carbon dioxide, which can draw them out even in daylight.

So while they don’t prefer to be out during the day, they will if they need to. The key is knowing where to look and what to look for. If you suspect an infestation, it’s worth acting fast. A professional bed bug exterminator can assess your situation and eliminate the pests before they spread further.

Where Do Bed Bugs Hide During the Day?

If you’re wondering how to find bed bugs in daylight, the best approach is to check areas where they like to hide. Since bed bugs dislike bright light, they squeeze into tight, dark spaces near where people sleep or sit for long periods. Here’s where you should check:

1. Mattress Seams & Bed Frames

• Look along the seams, folds, and edges of your mattress and box spring.
• Use a flashlight to check for live bugs, eggs, shed skins, or tiny black fecal spots.
• Lift your mattress and inspect the bed frame, headboard, and cracks in the wood.

2. Couches, Chairs & Upholstery

• Remove cushions and check along the seams and under the fabric.
• Examine the wooden joints and crevices of furniture, as bed bugs can slip into these tiny gaps.
• Pay close attention to where people sit most often, since bed bugs stay close to their food source.

3. Baseboards & Wall Cracks

• Run a flashlight along baseboards and floorboard gaps.
• Look for black fecal stains or tiny eggs near the edges of carpets or hardwood floors.

4. Electrical Outlets & Light Switches

• Carefully remove outlet covers (if safe to do so) and shine a light inside.
• Bed bugs use these hidden spaces to move between rooms, especially in apartment buildings.

5. Carpets & Rugs

• Inspect edges of carpets, especially near furniture.
• Look underneath rugs, particularly if they’re in a bedroom or living area.

How to See Bed Bugs in Bright Light During the Day

Since bed bugs prefer dark, hidden spaces, they aren’t easy to spot in broad daylight. But with the right technique, you can increase your chances of finding them:

• Use a flashlight to shine into cracks, seams, and corners.
• Run a credit card along crevices to force bed bugs out of tight spots.
• Look for tiny black fecal stains, which are often easier to find than live bugs.
• Check for eggs—they’re tiny, white, and usually grouped together in hard-to-reach areas.

Patience is key. Bed bugs are small and good at blending in, so a thorough inspection is necessary.

Signs of Bed Bugs Even If You Can’t See Them

You might not always catch bed bugs in the act, but there are plenty of clues that suggest they’re around. Look for these telltale signs:

• Rust-colored stains on sheets or mattresses (caused by crushed bed bugs).
• Musty, sweet odor—a strong, unpleasant smell from a large infestation.
• Itchy red bites on your skin, often in clusters or straight lines.
• Tiny white eggs or shed skins near common hiding spots.

If you notice one or more of these signs, but don’t see actual bed bugs, they’re likely well hidden. In that case, setting up bed bug traps or calling a professional for an inspection may be necessary.

How to Lure Bed Bugs Out During the Day

If you suspect bed bugs but can’t find them, here are some ways to increase the chances of seeing them in daylight:

• Move furniture around gently—shifting their hiding spots can make them scurry into the open.
• Use a hairdryer on low heat along seams and crevices to encourage them to emerge.
• Place interceptor traps under bed legs—bed bugs trying to reach you at night will get caught.

These tricks won’t get rid of bed bugs, but they can help confirm their presence so you know what you’re dealing with.

What to Do If You Find Bed Bugs

If you confirm bed bugs are active during the day, take action quickly before the infestation spreads:

• Don’t rely on DIY sprays—store-bought insecticides often make bed bugs scatter instead of killing them.
• Wash all bedding, clothes, and fabrics in hot water and dry them on high heat.
• Vacuum thoroughly, especially along seams, baseboards, and carpets.
• Call a professional pest control service to develop a treatment plan.
