Bed bugs can live for as long as 4.5 months or more in an empty house before completely dying off. The two primary factors that determine how quickly or slowly the bed bugs could die off are the existence of a blood meal host, and the temperature of the house.
Don't count on bed bugs to go away on their own. In theory, they can. In practice, they don't unless several highly specific circumstances occur. Your best bet is professional bed bugs treatment.
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.
Since the answer to the main question “are bed bugs disappearing?' ” is no, the best way to get rid of bed bugs is with heat. A bed bug treatment with heat kills all stages of the bed bug life cycle, including the eggs.
Heat treatments are highly effective as they can get rid of 95% of bed bugs with just a single treatment.
It's best to keep the infestation localized to as few rooms as possible. This will also make remediation easier. Do continue to sleep in your bedroom after identifying a bed bug infestation. If you move rooms or start sleeping on the couch you run the risk of contaminating these other areas of your home.
Often a great indicator of how long an infestation has been around is the number of adult bed bugs present. Generally it takes at least seven weeks for a bed bug to grow from an egg to an adult, so there should be no new adults from eggs during that period.
Heat is known to be a very effective bed bug killer and it can be used in many different ways to treat infestations. For instance, heat in the form of steam can be used to treat bed bugs in carpets, behind base boards and on upholstered furniture.
Completely enclose your mattress and box spring in zippered bed encasements available from allergy or pest control supply companies. Put duct tape over the zipper, because zippers have a space where bedbugs can enter or escape. Mattresses can also be wrapped and sealed in plastic film.
Light Bed Bug Infestation
Minimal fecal staining (small black stains in areas of travel, feeding, and harborage). Fecal stains will be anywhere the bed bugs hide or travel and can be used to detect hot spots. Minimal cast skins (exuviae are the skins shed during the molting process).
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.
Bed bugs live primarily indoors, giving them the heat they need to survive the winter. As long as they have a food source as well as the warmth they need, they'll happily remain active in your home throughout the year. If they don't have a food source, they can go for several months without eating and still survive.
You may not like to hear the answer, but it is better to sleep in the bed where you saw the bed bug. The reason is that if you move and sleep in another room, the bugs in your bed will eventually begin to follow you. Bed bugs have to feed on blood every 4-7 days.
Where Do Bed Bugs Hide on Your Body? Bed bugs do not typically hide on the body. They prefer to feed, then move back to their hiding place until they are hungry again. In some cases, they may hide in your clothes or the soles of your shoes.
First, don't panic. Not everyone who stays in a bed bug infested room will take bed bugs home. Nevertheless, it's a good idea to act as if you may have picked up a stray bed bug or two. The most likely place to pick up bed bugs in luggage is on, or next to, the bed.
Reduce clutter in your home to reduce hiding places for bed bugs. Vacuum frequently to remove any successful hitchhikers. Be vigilant when using shared laundry facilities. Transport items to be washed in plastic bags (if you have an active infestation, use a new bag for the journey home).
Bed bugs are easy to kill using heat. Their thermal death point is reported to be 114-115° F. Putting infested clothing in a hot dryer is an excellent way of killing bed bugs and their eggs. Heat can also be used to kill bed bugs and their eggs in furniture and carpeting.
Steam vapour may be used on all soft and hard surfaces especially on seams and in little crevices. Washing in water above 60ºC (to ensure every bug stage will be killed) and drying infested linen in a dryer is an effective method of killing bed bugs.
While you may think that just one tiny speck of a pest may not be a big deal, it can signal you have a full-on infestation growing under your nose. If you find even just a few bed bugs, you need to call in the professionals.
The number of treatments needed to get control is (national average) 3 to 4 treatments. The first step to treating the problem yourself is taking your bed apart. The frame should be completely deconstructed to reach all cracks and crevices. For any unreachable areas, aerosols are useful.
Do Bed Bugs Usually Stay In One Room? Since bed bugs do not have wings and do not jump, some people incorrectly assume that they tend to stay in one room and not travel much. However, this is not true. Bed bugs move around quickly and seek any place where they can find their next blood meal (i.e. humans).
Bed bugs also don't like light and will run for cover when lights are on. If the infested room is dark, and the uninfested rooms are lighted all night, it discourages them from wandering. They tend to bite exposed areas of the body, permitting a quick get-away when lights come on.
