Bedbugs: How to Identify and Prevent an Infestation

Understanding Bedbugs

Bedbugs are small insects that thrive on the blood of animals and humans. Adults are reddish-brown, wingless, and about the size of an apple seed. Nymphs, or young bedbugs, are smaller and can appear translucent or yellowish. Bedbug eggs are tiny and white, making them difficult to spot.

Common Bedbug Habitats

Bedbugs can be found in a variety of locations, including:

Apartments
Shelters
Hotels
Rooming houses
Dorm rooms
Cruise ships
Buses
Trains

Size of Bedbugs

Adult bedbugs measure approximately 5 to 7 millimeters in length, comparable to the size of Abraham Lincoln’s head on a penny.

Global Presence of Bedbugs

Bedbugs are present worldwide. They are not restricted to developing countries but are also common in the U.S., Canada, the U.K., Asia, Africa, and South America. These pests can infest any location where they can access a blood meal.

Identifying Bedbugs

Adult bedbugs have flat bodies similar in size to an apple seed. After feeding, they swell and turn reddish. Their flattened bodies enable them to fit into narrow spaces, about the thickness of a credit card.

How Bedbugs Spread

Bedbugs typically infiltrate homes from other infested locations. They can travel between apartments, hitch a ride on used furniture, luggage, or clothing. Their small size and ability to hide make them difficult to detect.

Health Impact of Bedbugs

While bedbugs do not transmit diseases, their bites can be itchy and uncomfortable. Scratching bites can lead to skin infections. Some individuals may experience allergic reactions, such as hives, blisters, or intense itching. Consult a doctor if you experience these symptoms.

Signs of Bedbug Infestation

Early indications of a bedbug infestation include:

Small, itchy bites on the skin, often in clusters
Blood spots on sheets or mattresses
Tiny, pale yellow eggs or eggshells
Bedbug feces, appearing as black dots
Shed bedbug skins
A sweet, musty odor around the bed
Visible bedbugs in your bed

Inspecting for Bedbugs

Examine your mattress and bed closely, particularly the crevices. Bedbugs often hide in seams, tags, and piping of the mattress or box springs, as well as cracks in the bed frame or headboard. They can also be found:

In the seams of sofas and chairs
In curtain folds
In drawer joints
In electrical outlets and appliances
Under loose wallpaper or paint
In box springs and bedding
Under carpeting near baseboards
On luggage and in boxes

Dealing with Bedbug Bites

Bedbugs are mainly active at night and bite while you sleep. Their bites can cause itchy spots on your skin. On light skin, the bites appear red; on darker skin, they may be purple. Bites can be in straight rows, zigzag patterns, or randomly scattered. Unlike flea bites, bedbug bites lack a red spot in the center.

Bedbug Allergy and Rash

Allergic reactions to bedbug bites result in severe itching, hives, or blisters. If you experience these symptoms, consult a doctor. Other skin conditions, such as hives or heat rash, can resemble bedbug bites. Look for signs of bedbugs to confirm an infestation.

Eliminating Bedbugs

To get rid of bedbugs, start with these home remedies:

Wash bedding, curtains, and clothing in hot water and dry on high heat.
Use a stiff brush to scrub mattress seams before vacuuming.
Vacuum your bed and surrounding areas daily. Dispose of the vacuum bag in a sealed plastic bag outside.
Use a tightly woven, zippered cover on your mattress and box springs.
Repair cracks in plaster and glue down loose wallpaper.
Declutter around your bed and move it away from walls and furniture.

Bedbug Spray

Chemical treatments are often required to completely eradicate bedbugs. Use only EPA-approved pesticides specifically labeled for bedbug control. It’s advisable to hire a professional exterminator with experience in treating bedbugs.

Preventing Bedbugs

Preventing bedbug infestations involves:

Using protective covers on mattresses and box springs
Reducing bedroom clutter
Regular vacuuming, including mattresses and upholstered furniture
Keeping luggage off beds and floors during travel
Washing and drying travel clothes on high heat
Inspecting used furniture before bringing it home
Using plastic bags for laundry in shared facilities

Common Myths About Bedbugs

Myth 1: Foam Mattresses Prevent Bedbugs

While bedbugs cannot live in foam, they can still hide in crevices of bed frames and other parts of the bed.

Myth 2: Bedbugs Travel Only on Fabric

Bedbugs can also crawl through electrical outlets and down hallways. They do not need fabric to move around.

Myth 3: Infestations Require Throwing Away Belongings

Professional pest control treatments can make your belongings safe to use again after treatment.

Myth 4: Bedbugs Are Gone for Good After Treatment

Bedbugs can survive for several months. Professional exterminators may need to follow up to ensure complete eradication.

When to See a Doctor

If you experience severe itching, hives, blisters, or signs of an allergic reaction, contact your doctor for treatment.

Takeaways

Bedbugs are resilient pests that can live almost anywhere and travel easily. Knowing the signs of bedbugs and taking preventative measures can help you avoid bringing them into your home. If you suspect an infestation, seek professional help. For allergic reactions to bedbug bites, consult your doctor.
