What to Look For Before Checking for Bed Bugs

When checking for bed bugs, recognising the signs and knowing what these pests look like is crucial for early detection.

Signs of Bed Bugs

  • Bites on Skin: Bed bug bites often appear as small, red, itchy welts. They can look similar to mosquito bites or hives and may cause a mild to swollen reaction in most people. However, some people do not react to bites at all, making other signs more important.

  • Blood Stains: You might notice tiny rust-coloured or blood stains on your bedding or mattresses, which occur when bed bugs are crushed after feeding.

  • Dark Spots: Small dark or black spots on mattresses, bedding, or furniture are bed bug faecal spots, a clear sign of infestation.

  • Shed Skins and Eggs: Bed bugs shed their skins as they grow. These pale yellow, translucent exoskeletons can be found in hiding spots. Tiny, pearly-white eggs about 1mm in size are often clustered in crevices.

  • Musty Odour: In heavy infestations, a sweet, musty odour may be noticeable, caused by bed bug scent glands.

What Bed Bugs Look Like

Bed bugs are small, oval-shaped, and wingless insects, typically about 5-7mm in size—roughly the size of an apple seed. Their colour varies depending on feeding status:

  • Unfed Bed Bugs: Pale yellow or light brown.

  • Fed Bed Bugs: Reddish-brown and swollen after feeding on blood.

Bed bugs have flat bodies that allow them to hide in narrow crevices such as mattress seams, box springs, bed frames, couches, and cracks in walls. Their small size and ability to hide make them difficult to spot, so thorough inspection is essential.

How to Check for Bed Bugs: A Step-by-Step Guide

Detecting bed bugs at home begins with a careful inspection of sleeping and resting areas. These tiny pests are brilliant at hiding, so you’ll need to be thorough and patient. When checking for bed bugs, a flashlight and a flat-edged tool are essential and this guide will teach you how to check for bed bugs effectively:

Inspect the Bed Thoroughly

The bed is the main hotspot for bed bugs, as they like to stay near their food source—you. Focus on these key areas:

  • Mattress and Box Spring: Check seams, folds, and tufts for live bed bugs (small, reddish-brown, and oval-shaped), tiny white eggs (about 1mm long), or empty eggshells.
  • Bed Frame and Headboard: Look along joints, cracks, and screw holes for hiding bugs or signs of activity.
  • Bedding: Examine sheets, pillowcases, and blankets for small black or dark brown spots (bed bug droppings) or rust-coloured blood stains (from crushed bugs after feeding).

Tip: Use a magnifying glass if needed—bed bugs and their eggs are small and easy to overlook.

Examine Furniture and Surrounding Areas

Bed bugs aren’t confined to beds. They can spread to nearby furniture and walls, so widen your search:

  • Upholstered Furniture: Inspect settees, chairs, and cushions, paying close attention to seams, folds, and under cushions where bugs may lurk.
  • Walls and Decor: Check behind picture frames, wall hangings, and electrical sockets for shed skins (translucent, bug-shaped husks) or live bugs.
  • Furniture Crevices: Use a vacuum cleaner with a crevice tool to probe deep into cracks. Avoid moving infested items out of the room—this can accidentally spread the problem.

How to Check Clothes and Personal Belongings for Bed Bugs

Bed bugs can easily hitch a ride on your clothing, luggage, and other personal belongings, especially after travel. To prevent bringing these pests into your home, it’s important to inspect and handle your items carefully:

  • Inspect Luggage Thoroughly: Before unpacking, examine your suitcase inside and out, paying close attention to seams, pockets, and folds where bed bugs may hide. Use a torch to spot any live bugs, eggs, or tiny dark droppings.

  • Check Clothing Carefully: Look over your clothes, especially those worn during travel, for any signs of bed bugs. Focus on seams, cuffs, and folds. If you notice bites or suspect contamination, isolate the clothing in sealed plastic bags until washing.

  • Wash and Dry Immediately: Upon returning home, wash all travel clothes in hot water (at least 60°C) and tumble dry on a high heat setting for at least 30 minutes. Heat effectively kills bed bugs at all life stages, including eggs.

  • Handle Items with Care: Avoid bringing luggage or clothing directly onto beds or upholstered furniture. Instead, place bags on hard surfaces like bathroom floors or metal racks to reduce the chance of bed bugs spreading.

  • Consider Freezing Non-Washable Items: For items that cannot be washed, such as shoes or delicate fabrics, placing them in a sealed plastic bag in the freezer for 3-4 days can help eliminate bed bugs.

By following these steps, you can reduce the risk of bed bugs traveling with you and infesting your home, keeping you and your belongings safe.

Use Tools to Uncover Hidden Bed Bugs

Some bed bugs hide in tricky spots. Equip yourself with the right tools:

  • Torch: Shine a torch into dark corners, behind headboards, and inside cracks to spot bed bugs or their eggs.
  • Stiff Brush: Gently scrub along seams and crevices to dislodge eggs or bugs from their hiding places. Pair this with a torch for better visibility.

Tip: Wear gloves to avoid direct contact with bugs or allergens they leave behind.

Set Traps to Confirm Activity

If you suspect bed bugs but haven’t found solid evidence, traps can help:

  • Bed Leg Traps: Place interceptor traps (small cups or sticky traps) under each bed leg. These catch adult bed bugs as they move at night searching for a meal.
  • Monitor Overnight: Check traps the next morning for captured bugs—a clear sign of an active infestation.

How to Check for Bed Bugs in Hotels

Travelling can expose you to bed bugs, especially in hotels. To avoid bringing them home, take these precautions upon arrival:

  • Inspect the Bed: Pull back the sheets and check mattress seams, headboards, and under the bed for live bugs, eggs, or dark droppings.
  • Check Luggage Areas: Examine hotel furniture near the bed, like chairs or luggage racks, for signs of infestation. Keep your suitcase off the bed and floor—use the bathroom or a metal rack if possible.
  • Use a Torch: Bring a small torch to shine into crevices and dark corners where bed bugs might hide.
  • Monitor Your Stay: If you wake up with itchy bites or spot blood stains on sheets, inform hotel staff immediately and request a room change—preferably in a different part of the building.
