Bed bugs do not multiply when killed. Like all living insects, they die when properly exposed to lethal temperatures or targeted chemicals. The belief that they multiply stems from the fact that killing only a few visible bugs does not eliminate unhatched eggs or bugs hiding out of sight.
Killing bed bugs alone does not increase their population; their multiplication relies on reproduction, not death. Females can lay eggs without males, but the eggs won't hatch if the bed bugs are killed before breeding. Proper treatment methods target both bugs and eggs to prevent further reproduction and infestation.
To stop bed bugs from reproducing, you must employ an Integrated Pest Management (IPM) approach that uses physical extermination (heat and vacuuming), mattress encasements, and specific insecticides like Insect Growth Regulators (IGRs) or targeted residual sprays to kill both adults and eggs.
Bed bugs ex- posed to 113°F will die if they receive constant exposure to that temperature for 90 minutes or more. However, they will die within 20 minutes if exposed to 118°F. Interestingly, bed bug eggs must be exposed to 118°F for 90 minutes to reach 100% mortality.
Given the right environment, bed bug populations can double roughly every 16 days. These eggs are about the size of a pinhead and are often deposited in hidden, hard-to-reach areas such as mattress seams, cracks in furniture, or crevices in walls.
But there are a few ways to tell the difference. Pattern: Bed bug bites may appear in a linear pattern, as a series of multiple bites in a row or a zigzag. Flea bites often show up in clusters of three (sometimes also in a straight line).
Bed bugs are driven out of hiding primarily by carbon dioxide from human breath and body heat. As they detect these biological cues, they emerge from their harborages—typically cracks, crevices, and mattress seams—to seek a host and feed.
Bed bugs are most active at night, specifically between midnight and 5:00 a.m.. They prefer to feed when their human host is in deep sleep, as they are drawn out by the warmth of a body and the carbon dioxide exhaled while breathing.
Exterminators use a combination of methods—such as heat treatments, professional-grade chemical insecticides, and desiccant dusts—to fully eliminate bed bugs. Rather than relying on a single product, they use a strategic approach targeting all life stages (eggs, nymphs, and adults) to bypass the bugs' natural defenses.
No, bed bugs cannot live in your hair on your head. They lack the specialized claws that insects like lice or ticks use to grip hair shafts. Bed bugs are also not parasitic and prefer to hide in static, dark crevices—like mattress seams and furniture.
Mattresses and pillows make potential habitats for bed bugs. Pillows may also be host to bed bug eggs, making them a potential point of bed bug infestations.
Yes, bed bugs can technically survive a washing machine cycle. While the water submersion, agitation, and detergent will kill some bugs, the water temperature rarely stays high enough to eliminate all the adults, nymphs, and eggs. The crucial step that actually kills them is placing the items in the dryer on high heat.
You can consider bed bugs officially gone when you go 30 to 60 days without any signs of activity. Because bed bugs can survive for months without feeding, a lack of bites over just a week or two does not mean they are fully eradicated.
No, bed bugs do not stay on your body after a shower. They do not cling to human skin like ticks or lice and do not live on their hosts. Bed bugs only crawl onto you to feed (typically for 5 to 10 minutes) and then immediately retreat to their hiding spots in mattresses, furniture, or wall crevices.
A female bed bug will produce between 1- 7 eggs per day for about 10 days after a single blood meal. She will then have to feed again to produce more eggs. A female can produce between 5 and 20 eggs from a single • blood meal.
Exterminators widely agree that bed bugs are the hardest pest to get rid of. Their ability to hitchhike, resilience against over-the-counter pesticides, and talent for hiding in microscopic crevices make DIY eradication nearly impossible.
No, Dawn is not an insecticidal soap. Dawn is a synthetic detergent designed as a heavy-duty degreaser. True insecticidal soaps are made of potassium salts of fatty acids and are specially formulated to target pests without damaging plants.
No, bed bugs do not only live in mattresses. While mattresses provide easy access to a food source (you), these opportunistic insects will hide in any dark, undisturbed crack, crevice, or fabric fold within about 5 feet of where you sleep or sit.
Bed bug season normally begins at the end of spring each year and ends at the beginning of the month in November, coinciding with increased summer travel. Bed bugs do not reproduce faster this time of year, it simply takes time before people start to notice they've got a problem.
In 2025, the top five bed bug states were Ohio, Texas, Florida, California, and Pennsylvania. Bed bug populations are tied to climate, housing trends, and travel hubs. The best way to avoid bringing bed bugs home while traveling is knowing how to identify signs of their presence in the areas where you rest or sleep.
To find a bed bug nest—known as a harborage—you need to carefully search dark, tight spaces close to where you sleep. Look for clusters of live bugs (which are brown, flat, and the size of an apple seed), tiny pale yellow eggs, dark fecal smears, or translucent shed skins.
No, you cannot get bed bugs by simply being near or talking to someone who has them. Unlike lice or ticks, bed bugs do not live on the human body or latch onto your hair or actively worn clothes to travel from person to person.
Kill the Bed Bugs
Yes, bed bugs can absolutely live on, in, or under your pillow. Because they seek out dark crevices and places close to their human host to feed, the seams, pillowcases, and zippers of pillows are common hiding spots.
