Bed bugs are most active between midnight and 3 am. They are rarely active during daylight hours, and only come out when attracted by the warmth and carbon dioxide released from a body at rest.
Bed bugs are generally considered to be nocturnal and prefer to forage for a host and take a blood meal during the night. They also will come out in the daytime or at night when lights are on, in order to take a blood meal, especially if there were no human hosts in the structure for a while and they are hungry.
Bed Bug Feeding
The bugs can bite several times in a night to become full but only feed about once every one or two weeks. People that have only small numbers of the bugs in their homes may not experience new bites every night.
Closely inspect the grooves in hardwood flooring, especially beneath or around the bed. Look along the bottom and top of the baseboards. Pay special attention to any cracks in the wood or nail holes. Peel back the carpeting from the tack strip to look for the bugs.
You can either manually inspect the same areas each day, or some clients find it helpful to put a sticky adhesive trap around the bed legs which would pick up bed bugs that are on the move. If no bed bugs show up in the trap after several days, that's one indication that they have been completely eradicated.
Sealing items like these in plastic bags and placing in a freezer will kill off bed bugs but you need to keep the items in a freezer at 0 degree F or lower for up to five days to ensure all the bugs are dead. Other items that can be frozen include shoes, picture frames, jewelry, small toys, and small electronics.
Pyrethroids are synthetic chemical insecticides that act like pyrethrins. Both compounds are lethal to bed bugs and can flush bed bugs out of their hiding places and kill them.
Myth: Bedbugs won't come out if the room is brightly lit. Reality: While bedbugs prefer darkness, keeping the light on at night won't deter these pests from biting you.
Rusty or reddish stains on bed sheets or mattresses caused by bed bugs being crushed. Dark spots (about this size: •), which are bed bug excrement and may bleed on the fabric like a marker would. Eggs and eggshells, which are tiny (about 1mm) and pale yellow skins that nymphs shed as they grow larger.
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. A possible sign that bed bugs have infested pillows may be the appearance of bites.
Myth. There is no scientific evidence to suggest that baking soda is a successful home remedy for bed bugs. Baking soda actually breaks down when it comes into contact with water, so the idea that it can absorb the thick fluids found on a bed bug shell is quite questionable.
Washing bed sheets and other bedding in high temperatures
Washing your bed sheets and other bedding such as pillowcases and blankets in hot water is a simple and inexpensive way to stop bed bugs from biting you right at where you sleep every night.
One scent that bed bugs find appealing is dirty laundry or dirty bedding because of how it smells once it's come in contact with humans. Research has shown that bed bugs prefer previously worn clothing and used bedding, which is why you shouldn't leave these items on the floor close to your bed.
Baby powder can be used to smother and suffocate bed bugs. A 70% isoprophyl solution will also kill bed bugs and their eggs on contact. Both of these methods, however, may require multiple applications to fully eliminate an infestation.
At Thrasher Termite & Pest Control, we've found live bed bugs inside of vacuum cleaners. Vacuums suck up small particles, including bed bugs and bed bug eggs. Vacuums have lots of nooks and crannies for bed bugs and bed bug eggs to hide: the rug beater, the corrugated hose, the filters, the bag or the dirt receptacle.
Wash bedding and clothes in hot water for 30 minutes. Then put them in a dryer on the highest heat setting for 30 minutes. Use a steamer on mattresses, couches, and other places where bedbugs hide. Pack up infested items in black bags and leave them outside on a hot day that reaches 95°F (35°C) or in a closed car.
They can come from other infested areas or from used furniture. They can hitch a ride in luggage, purses, backpacks, or other items placed on soft or upholstered surfaces. They can travel between rooms in multi-unit buildings, such as apartment complexes and hotels.
Using heat is the best way to force bedbugs to leave their hideaway. You can use heat to convince the bedbugs that the host is nearby. They will come out and begin looking for food. You can also try washing your clothes on high heat.
“People may have bed bugs and not know it because many people have no physical reaction to bed bug bites,” Dr. Harrison says. “That's why it's important for people everywhere to inspect for bed bugs regularly.”
A laboratory study that is decades old showed bed bugs being dormant for about 500 days; however, that is not typical since bed bugs in a natural setting will attempt to consume a blood meal rather than remain dormant for such a long period.
One reason is that bed bugs can get all over your clothing and make the infestation even worse. For this reason, you should take any clothes that may have potentially come in contact with the infested area and clean them immediately to eliminate the threat of bed bugs spreading when you wear your clothing.
