What Are Bed Bugs? Size, Appearance and Life Cycle
At Mattress Miracle, 441 1/2 West Street in Brantford, we talk to customers about bed bug prevention more than you might expect. Since 1997, we have helped thousands of families protect their mattress investments, and bed bug awareness is part of that conversation. Here is what you need to know.
Bed bugs (Cimex lectularius) are small, wingless, parasitic insects that feed exclusively on blood. According to Health Canada, adult bed bugs are about 4-7 mm long, roughly the size of an apple seed. They are oval-shaped and flat when unfed, becoming swollen and more reddish-brown after a blood meal.
Their life cycle has five nymph stages before reaching adulthood. A single female can lay 200-500 eggs in her lifetime, which is why small problems become large infestations quickly. Eggs are tiny (about 1 mm), whitish, and often laid in clusters of 10-50 in crevices near sleeping areas.
Bed Bug Biology: What the Research Says
A 2023 review published in the Journal of Medical Entomology confirmed that bed bugs can survive 2-6 months without feeding under typical room conditions, and up to a year in cooler environments. This is why they persist in vacant apartments and hotel rooms between guests. The Canadian Centre for Occupational Health and Safety (CCOHS) notes that bed bugs are not known to transmit diseases to humans, but their bites cause allergic reactions in approximately 70% of people, ranging from mild itching to severe welts requiring medical attention.
Medical Disclaimer: The information in this article is for educational purposes only. If you are experiencing severe reactions to bed bug bites or suspect a large infestation, consult a healthcare professional and a licensed pest control operator.
What Do Bed Bugs Look Like at Each Stage
One of the most common searches we see is "what does bed bugs look like" or "can you see bed bugs with the naked eye." The answer is yes, adult bed bugs are visible to the naked eye, though they are experts at hiding.
Bed Bug Appearance by Life Stage
- Eggs: Tiny (1 mm), white to pearl-coloured, grain-of-rice shaped. Found in clusters in mattress seams, bed frame joints, and baseboards. Very difficult to spot without a magnifying glass.
- Nymphs (Stage 1-2): 1-2 mm, nearly translucent or light yellow. Almost invisible on white sheets. After feeding, they turn bright red from the blood meal.
- Nymphs (Stage 3-5): 2-4 mm, progressively darker. Start to resemble small adults. Easier to spot, especially after feeding.
- Adults (unfed): 4-7 mm, flat, oval, reddish-brown. About the size and shape of an apple seed. They can fit into cracks as thin as a credit card.
- Adults (fed): Swollen, elongated, darker reddish-brown. Noticeably larger and rounder than unfed bugs. This is when most people first spot them.
Red bed bugs (the bright red ones you might see) are simply bed bugs that have recently fed. The colour fades back to brown as they digest. White or very pale bed bugs are typically early-stage nymphs that have not yet fed.
Bed bug legs are short relative to their body, with six legs total. They do not jump or fly. They crawl, and they crawl faster than most people expect, roughly 1 metre per minute on flat surfaces.
Bed Bug Bites: What They Look Like and How to Treat Them
Bed bug bites are one of the first signs that something is wrong. According to the Cleveland Clinic, bites typically appear as small, raised, red welts that are itchy. They often occur in clusters or lines of three (sometimes called "breakfast, lunch, and dinner" by pest control professionals) on areas of skin exposed during sleep: arms, neck, shoulders, face, and legs.
Bed Bug Bite Characteristics
- Appearance: Red, raised welts, often with a darker red centre. Similar to mosquito bites but typically in groups or lines.
- Pattern: Clusters of 3-5 bites in a row or zigzag pattern. This happens because the bug feeds, pauses, moves slightly, and feeds again.
- Timing: Bites may not appear for 1-14 days after being bitten. Some people react immediately, others take up to two weeks.
- Location: Exposed skin while sleeping. Arms, shoulders, neck, and face are most common. Bed bugs rarely bite through clothing.
- Important: About 30% of people show no visible reaction to bed bug bites. The absence of bites does not mean the absence of bed bugs.
A bed bug rash is an allergic reaction to the bug's saliva, which contains anticoagulants and anaesthetics (which is why you do not feel the bite happening). The rash can range from mild redness to large, swollen hives in sensitive individuals.
How to Treat Bed Bug Bites
For most people, bed bug bites heal on their own within 1-2 weeks. To manage symptoms:
- Wash the bites gently with soap and warm water
- Apply an over-the-counter hydrocortisone cream (1%) to reduce itching
- Take an oral antihistamine (like diphenhydramine) if itching is severe
- Avoid scratching, which can lead to secondary infection
- If bites become infected (increasing redness, warmth, pus), see a doctor
For more detail on treating bites, see our bed bug bites guide.
How Do You Get Bed Bugs? Common Causes
This is one of the most important questions to answer honestly: bed bugs are not a sign of poor hygiene. They are hitchhikers. According to Health Canada, bed bugs spread by travelling in luggage, clothing, used furniture, and other personal belongings. They do not discriminate between clean and dirty homes.
How Bed Bugs Spread
- Travel: Hotels, hostels, and short-term rentals are the most common source. Bugs crawl into luggage, and you bring them home.
- Used furniture: Second-hand mattresses, bed frames, couches, and dressers can harbour bed bugs. This is one reason we always recommend buying a new mattress from a trusted retailer like Mattress Miracle rather than used.
- Multi-unit buildings: Apartments and condos allow bed bugs to travel between units through walls, pipes, and electrical outlets.
- Visitors: A guest can unknowingly bring bed bugs in their bags or clothing.
- Public transport and workplaces: The CCOHS notes that bed bugs can be found in offices, cinemas, and transit vehicles, though this is less common than residential spread.
What attracts bed bugs is simple: carbon dioxide and body heat. They are drawn to sleeping humans because we exhale CO2 and generate warmth. Contrary to popular belief, bed bugs are not attracted to dirt, food crumbs, or clutter. However, clutter does give them more places to hide, making infestations harder to detect and treat.
Are bed bugs nocturnal? Mostly yes. They prefer to feed in the dark, typically between 2 AM and 5 AM. However, bed bugs will feed during the day if they are hungry enough, particularly in heavily infested environments. Do bed bugs come out during the day? They can, but it usually indicates a significant infestation.
Signs of Bed Bugs: How to Check Your Mattress
At Mattress Miracle, we always tell customers: the best time to find bed bugs is before they find you. Early detection makes treatment faster, cheaper, and less stressful. Here is how to check.
Step 1: Strip Your Bed Completely
Remove all sheets, pillowcases, and the mattress protector. Check each item for small brown or red spots (fecal stains or blood). Place bedding directly into a garbage bag and wash on hot (60 degrees Celsius minimum).
Step 2: Inspect the Mattress Seams
Using a flashlight, examine every seam, piping edge, and tuft of your mattress. Bed bugs prefer tight spaces. Look for live bugs, shed skins (translucent husks), dark fecal spots (they look like tiny ink dots), and eggs (white specks in clusters).
Step 3: Check the Box Spring and Bed Frame
Flip or tilt the box spring and inspect the fabric stapled to the bottom. Check bed frame joints, screw holes, and any cracks in wood or metal. Bed bugs love the gap where the headboard meets the wall.
Step 4: Inspect Nearby Furniture
Check nightstands, dressers, baseboards, electrical outlet covers, and picture frames within 2 metres of the bed. Bed bugs typically stay close to their food source but will travel further in large infestations.
Step 5: Look for Blood Stains and Fecal Spots
Bed bug blood stains on sheets appear as small rusty or reddish smears (from crushed bugs during sleep). Fecal spots are darker, almost black, and about the size of a felt-tip pen dot. These spots do not wipe away easily and may bleed into fabric like ink.
If you find evidence of bed bugs, do not panic. Seal your bedding in plastic bags, contact a licensed pest control professional, and do not move furniture to other rooms (this spreads the infestation). For more on the detection process, see our bed bug detection and prevention guide.
Bed Bugs vs Ticks, Chiggers and Other Look-Alikes
Not every small brown bug in your bed is a bed bug. Here are the most common insects confused with bed bugs:
Bed Bug vs Tick vs Chigger
- Bed bug vs tick: Ticks have 8 legs (bed bugs have 6). Ticks embed into skin and stay attached, while bed bugs bite and retreat. Ticks are more rounded, bed bugs are flatter and more oval. A tick bite has a visible attachment point, a bed bug bite does not.
- Chiggers vs bed bugs: Chigger bites cause intense itching with a raised centre and tend to occur around ankles, waistbands, and skin folds. Bed bug bites are on exposed skin. Chiggers are nearly invisible (0.3 mm), while bed bugs are visible.
- Carpet beetles: Oval, with coloured scales (black, brown, or mottled). They do not bite but can cause skin irritation from shed hairs. Found near windows and light sources, unlike bed bugs.
- Bat bugs: Nearly identical to bed bugs but have longer hair on their thorax. Usually found in attics or near bat roosts. A professional may need a microscope to distinguish them.
How to Get Rid of Bed Bugs
This is where we need to be direct: for active infestations, call a licensed pest control professional. Health Canada recommends professional treatment for bed bug infestations and cautions against using unregistered pesticides or home remedies that can be ineffective or dangerous.
Professional Treatment Options
Licensed pest control operators in Canada use several approaches:
- Heat treatment: Raising room temperature to 50-60 degrees Celsius for several hours. Kills all life stages including eggs. Generally the most effective single-treatment option.
- Chemical treatment: Targeted application of registered insecticides to harbourage areas. Usually requires 2-3 visits over several weeks.
- Steam treatment: Direct application of steam to mattress seams, bed frames, and baseboards. Effective but requires thoroughness.
- Integrated approach: Most professionals combine methods for best results.
What About Home Remedies?
Searches for vinegar, rubbing alcohol, borax, tea tree oil, and hot water as bed bug treatments are common. Here is the honest truth: none of these are reliable treatments for bed bug infestations. The Canadian Pest Management Association notes that while some of these substances can kill individual bed bugs on contact, they do not reach bugs hiding in cracks, do not kill eggs, and can create false confidence that the problem is solved. Rubbing alcohol is also a fire hazard in the quantities needed. Does borax kill bed bugs? Does hot water kill bed bugs? Does tea tree oil kill bed bugs? In controlled lab conditions, direct contact with some of these substances can kill individual bugs. In a real home with bugs hiding in walls, frames, and furniture, these methods are not effective pest control. Save your money and call a professional.
After Treatment: Protecting Your Mattress
Once a professional has treated your home, protecting your mattress from reinfestation is critical. This is where a bed bug mattress encasement becomes essential, not optional.
Protecting Your Mattress from Bed Bugs
At Mattress Miracle, we carry mattress encasements specifically designed to prevent bed bug infestations and protect mattresses after treatment. There is an important difference between a mattress protector and a mattress encasement:
Mattress Protector vs Bed Bug Encasement
- Mattress protector: Covers the top and sides of the mattress like a fitted sheet. Protects against spills, stains, and allergens. Does NOT fully seal the mattress. Bed bugs can still get underneath. Good for general protection, not for bed bug prevention. Full comparison here.
- Bed bug encasement: Completely surrounds the mattress on all six sides with a zippered closure. Creates a sealed barrier that bed bugs cannot penetrate, enter, or escape from. If bugs are trapped inside, they eventually die without being able to feed. This is the standard recommended by pest control professionals. Our Tencel Bed Bug Encasement does exactly this.

Frequently Asked Questions
Can you see bed bugs with the naked eye?
Yes. Adult bed bugs are 4-7 mm long, about the size of an apple seed, and visible without magnification. Nymphs are smaller (1-4 mm) and harder to spot, especially when unfed. Eggs require a magnifying glass to see clearly. Use a flashlight when inspecting mattress seams and bed frame joints.
What kills bed bugs instantly?
Heat above 50 degrees Celsius kills bed bugs at all life stages. Professional heat treatments are the most effective option. Direct steam application also kills on contact. Chemical treatments from licensed operators work but typically require multiple applications over weeks. Home remedies like vinegar or rubbing alcohol are not reliable. Health Canada recommends professional pest control for infestations.
How common are bed bugs in Canada?
Bed bugs are present in every Canadian province and territory. According to Orkin Canada, bed bug calls have increased significantly since the early 2000s, with Toronto, Vancouver, and Winnipeg consistently ranking among the most affected cities. Multi-unit residential buildings and hotels are the most common sites. Bed bugs are not limited to any income level or cleanliness standard.
Do bed bugs only live in mattresses?
No. While mattresses and box springs are their preferred harbourage, bed bugs also hide in bed frames, headboards, nightstands, baseboards, electrical outlets, picture frames, and even behind wallpaper. In severe infestations, they can be found in couches, office chairs, and clothing. A bed bug mattress encasement protects your mattress but does not address bugs in other locations.
Should I throw out my mattress if I have bed bugs?
Not necessarily. Professional pest control treatment can save most mattresses. After treatment, install a bed bug encasement to trap any remaining bugs and prevent reinfestation. Replacing the mattress is only recommended if the infestation is severe and treatment has failed, or if the mattress is already old and due for replacement. If you do need a new mattress, Mattress Miracle in Brantford carries Canadian-made options starting from $399.
