How to Check for Bed Bugs: Complete Inspection Guide | Mattress Miracle

Sarah woke up with three small red marks in a line on her arm. Mosquito bites, she thought, though it was December. Then she saw another set on her ankle. Her stomach dropped. She had been travelling last week. Hotels. Luggage. Bed bugs.

She called us at Mattress Miracle, voice shaking. "How do I know for sure? I cannot sleep. I keep feeling things crawling on me."

We walked her through the inspection process. She found them. Not many, but enough. Early detection meant she could treat before the infestation spread. Her mattress was saved.

This is why knowing how to check for bed bugs matters. Catching them early is the difference between a $200 treatment and replacing everything you own.

Where Bed Bugs Hide

Bed bugs are flat, brown, and about the size of an apple seed. They hide in cracks and crevices during the day. They come out at night to feed.

Their favourite spots, in order of preference:

Mattress seams and tags. The piping along the edge of your mattress provides perfect cover. The fabric tag is another favourite. These are the first places to check.

Box springs. The corners and underside of box springs offer dark, tight spaces. Remove the dust cover if possible and inspect the wood frame inside.

Bed frame cracks. Wooden frames with joints and screw holes are ideal. Metal frames have screw holes and hollow tubes.

Headboards. Especially padded or fabric headboards. Check seams, tufting, and where the headboard meets the wall.

Nearby furniture. Nightstands, dressers, and chairs within six feet of the bed. Check drawer joints and underneath.

Brad has seen it all in his 38 years. "People tear apart their beds but forget the alarm clock on the nightstand. Bed bugs hide in electronics. They like the warmth."

The Step-by-Step Inspection

You will need a flashlight, credit card or thin plastic card, and white gloves if you are squeamish.

Step 1: Strip the bed completely. Remove all sheets, pillowcases, and mattress protector. Put them directly into a plastic bag. You will wash them on hot later.

Step 2: Inspect the mattress. Start with the seams. Use your flashlight and run the credit card along the piping. Look for:

- Live bugs (apple seed size, reddish-brown)
- Tiny white eggs (1mm, about the size of a pinhead)
- Shed skins (empty bug shells)
- Dark spots (bed bug feces, looks like ink dots)
- Tiny blood smears (from crushed bugs)

Check all four sides. Pay special attention to corners and the tag.

Step 3: Check the box spring. If possible, remove the fabric dust cover on the bottom. Inspect the wood frame, corners, and stapled areas. This is where many infestations start.

Step 4: Examine the bed frame. Check every screw hole, joint, and crack. Look under the frame where it touches the floor.

Step 5: Inspect nearby areas. Nightstands, dressers, baseboards, electrical outlets, and carpet edges within six feet of the bed.

What You Are Looking For

Talia at our Brantford showroom has trained hundreds of customers. She tells them to remember three things.

Spotting. Bed bug feces looks like someone dotted your mattress with a black felt pen. These spots do not wipe off easily. They are often found in clusters.

Shedding. As bed bugs grow, they shed their skins five times. These translucent shells are left behind where they hide. Finding shed skins means bed bugs have been present for weeks.

Blood smears. If you roll over and crush a bed bug while sleeping, you will see small blood stains on your sheets. These are often the first sign people notice.

Live bugs are surprisingly hard to spot. They are flat and fast. They hide when light hits them. You are more likely to find the signs they leave behind.

When to Call a Professional

If you find bed bugs, you have two choices. Treat it yourself or call an exterminator.

For a few bugs caught early, DIY can work. You will need mattress encasements, interceptors for bed legs, and probably diatomaceous earth. Expect to spend $100-200 and several weeks of vigilance.

For established infestations, call professionals. Multiple rooms, bugs in furniture beyond the bedroom, or signs of eggs means the problem is bigger than DIY can handle. Treatment costs $500-2,000 but comes with guarantees.

Do not sleep in a different room. Bed bugs follow. They can sense carbon dioxide and body heat. Moving rooms spreads the infestation.

Protecting Your Mattress

If you travel frequently, you are at higher risk. Hotels, even expensive ones, have bed bugs.

Dorothy recommends these prevention steps:

Use mattress encasements. These zippered covers trap any bugs already in your mattress and prevent new ones from getting in. They are the single best investment for bed bug prevention.

Inspect hotel rooms before unpacking. Check the mattress corners and headboard. Keep luggage on the rack, not the floor or bed.

When you return home, wash and dry all clothes on hot immediately. Inspect your luggage outside if possible.

Frequently Asked Questions

How often should I check for bed bugs?

Check your mattress monthly during regular sheet changes. Inspect immediately if you notice bites, blood spots on sheets, or after travelling. Early detection is critical.

Can bed bugs live in memory foam mattresses?

Bed bugs can live on any mattress surface, including memory foam. They hide in seams, tags, and nearby furniture rather than inside the foam itself. A quality encasement prevents them from hiding in mattress crevices.

What do bed bug bites look like?

Bites appear as small red welts, often in lines or clusters of three. Not everyone reacts to bites. Some people have no visible marks while others develop significant welts.

Can I see bed bugs with the naked eye?

Yes, adult bed bugs are visible. They are about the size of an apple seed, reddish-brown, and oval-shaped. However, they are flat and hide well. Eggs and newly hatched nymphs are nearly impossible to see without magnification.

Will getting a new mattress solve my bed bug problem?

No. Bed bugs live in bed frames, baseboards, furniture, and walls. Replacing your mattress without treating the surrounding area wastes money. Solve the infestation first, then replace the mattress if needed.

If You Find Bed Bugs

Do not panic. Bed bugs are unpleasant but they do not transmit disease. You can handle this.

First, contain what you can. Put bedding in sealed plastic bags. Vacuum thoroughly and immediately dispose of the vacuum bag outside.

Second, encase your mattress and box spring immediately. This traps bugs inside and prevents more from entering.

Third, decide on treatment. DIY for small, early infestations. Professional for larger ones.

Once you are bed bug free, consider whether your mattress needs replacement. Bed bug stains and treatment chemicals can damage mattress materials. At Mattress Miracle, we offer options at every price point, from the ComfortCare at $1,619 for a queen to premium models.
