Bed bugs are primarily drawn out of hiding by the scent of carbon dioxide (CO2) and the warmth from a sleeping host, signaling a meal is available, with darkness, hunger, and disturbed hiding spots also encouraging them to emerge, often between midnight and 3 a.m.. They use chemical signals and antennae to detect body heat, CO2, and smells, acting like a "dinner bell" when conditions are right for feeding.
Because bed bugs are attracted to warmth where they're most likely to find their food source, using various methods to heat the suspected infected areas could be helpful. Try heating your bed (or any infected area) with a steamer, blow dryer, or heater to bring bugs out of hiding.
Use silicon caulk to seal cracks and crevices. This eliminates hiding places and gets the bugs out into the open. Remove infested items. Place them in a sealed plastic bag and treat them.
The two strongest attractants are heat and carbon dioxide, which mimic the warmth and breath of a sleeping human. They also respond to chemical signals, including pheromone trails, that help them follow paths to safe harborages or other bugs.
➡️ Bed bugs mainly hide in mattresses, bed bases, cracks, skirting boards and furniture near the bed. ➡️ To find a nest, inspect bedding, furniture and dark corners with a torch and magnifying glass, ideally at night when they are active.
Do not squish a bed bug as it will release the blood and any pathogens it may be carrying. Resist the urge to scratch the bites. your agency's policy in regards to whether a doctor's order is required.)
Around the bed, they can be found near the piping, seams and tags of the mattress and box spring, and in cracks on the bed frame and headboard. If the room is heavily infested, you may find bed bugs: In the seams of chairs and couches, between cushions, in the folds of curtains. In drawer joints.
Utilize light and heat sources
Insects are naturally attracted to light, so placing bright lights outside your home can lure them away from your living areas. Additionally, heat lamps can create a warm and inviting environment for bugs, causing them to come out of hiding in search of warmth.
Natural scents like tea tree oil and peppermint oil can help repel bed bugs when used around sleeping areas. Some oils, like neem and orange oil, may help kill bed bugs or slow down their ability to spread.
Bugs would be repelled by hanging a bear's skin in your room – presumably the sight was thought to frighten them into moving elsewhere. Placing bags of wormwood 'between your bed and sacking [bedding]' would similarly stop the insects from making themselves at home in mattresses.
Bed bugs are averse to slick surfaces like glass, plastic, and polished metals and stone. They can, however, grasp and cling onto textiles and porous materials like wood.
Bed bugs usually come from places where people sleep or rest for long periods. Hotels, motels, dorm rooms, and apartment buildings are frequent hotspots. Public transportation, movie theaters, and waiting rooms can also harbor bed bugs. Bed bugs often latch onto luggage, backpacks, purses, or clothing.
Don't move things from room to room. Moving things from the room with bed bugs to another room in the house may spread the bed bugs. Don't wrap items in black plastic and place in the sun. It will not get hot enough inside the bag to kill all the bugs.
Bed bugs, for all their reliance on human hosts for their blood meals, don't tend to make homes for themselves on human bodies. Unlike lice and other similar insects, bed bugs lack the proper anatomy to effectively cling to hair.
Take a close look at the bed, behind the headboard, behind picture frames, in drawers, behind the curtains, and on sofas and chairs. Travel with a flashlight or use the flashlight on your phone to get a better look.
They haven't fed in a while and need to find a host. Their usual hiding spots have been disturbed (such as after cleaning or moving furniture). The infestation is large, forcing them to spread into more exposed areas. They detect body heat or carbon dioxide, which can draw them out even in daylight.
Bed bugs are primarily attracted to scents associated with carbon dioxide, body heat, and the scent of human skin. They locate their hosts by detecting the carbon dioxide exhaled during respiration, body heat, and certain chemical compounds found on human skin, such as sweat and pheromones.
Bed bugs are nocturnal, often hiding during the day, making detection by crawling sensation less likely. Even if you don't feel them, visual signs like blood spots or shed skins can indicate their presence.
You can use your washing machine and dryer to kill bed bugs infesting clothes and other washable items. Clothes laundered in hot water and/or dried in temperatures hotter than 122°F for 20 minutes will kill all stages of bed bugs.
High heat (steam, hot dryer) and some contact sprays like rubbing alcohol or specific low-toxicity sprays kill bed bugs and their eggs instantly, but complete eradication requires persistent treatment like vacuuming, sealing cracks, using diatomaceous earth (DE), and washing items at high temperatures. While chemicals work, heat is highly effective, killing bugs in all life stages on contact, especially when temperatures reach 60°C (140°F) or higher, according to health.vic.gov.au and myhealth1st.com.au.
Bed Bugs: A Public Health Issue
Inspect Pillow Seams and Crevices
Bed bugs love to reside in tight, dark spaces. This makes pillowcase seams and crevices inviting hideouts.
Bed bugs can reproduce rapidly. Females will lay one to five eggs per day, and one female can lay between 200-300 eggs over her lifetime. The eggs are white, about 1/32-inch long, and are covered with sticky glue that keeps them attached to the surface where they are laid.
