Begin by reducing clutter in the room; things like clothes, books, and other personal belongings shouldn’t be left on the floor, as they make treatment more difficult and add hiding places for bed bugs and eggs. Seal those items in garbage bags and store them away from the room. Any clothing that was picked up or removed from dresser drawers should be dried on high heat for at least 45 minutes. Once treated, clothing that you don’t normally wear should be stored inside garbage bags outside of the infested room.
The exact causes of this resurgence remain unclear; it is variously ascribed to greater foreign travel, increased immigration from the developing world to the developed world, more frequent exchange of second-hand furnishings among homes, a greater focus on control of other pests, resulting in neglect of bed bug countermeasures, and increasing resistance to pesticides. Declines in household cockroach populations that have resulted from the use of insecticides effective against this major bed bug predator have aided the bed bugs' resurgence, as have bans on DDT and other potent pesticides.[medical citation needed]
The size of bed bug bites varies with a number of different factors. Bed bugs inject an anti-coagulant along with their saliva when they pierce the skin to take a blood meal. This anti-coagulant is mostly responsible for how a person reacts to the bite and determines the size of the bug’s bite. Since people will have various sensitivities to the bed bug’s bite, the size of the bite will vary, as well. Another factor that influences the size of a bed bug reaction is the number of times a person is bitten. Bite reactions of people bitten many times are also variable, and their response may be either more or less intense as the number of bites increases.
Do encasements work? Yes. When you put an encasement on your mattress or box spring you can lock bed bugs in and prevent new bed bugs from getting in. No chemical control is needed, so you don't have to worry about being poisoned by powders or some other toxin in your bed. The problem is that encasements by themselves, or when used with traps, are simply a bandaid. They are not likely to contain or stop a bed bug infestation. As mentioned above, this method can lead to the growth of an infestation and, ultimately, a prolonged and frustrating infestation.
You must repeat the entirety of Step 2 (except for the mattress and box spring treatment if you are encasing) every 7-10 days until no one in the home has bed bug bites and there is no further evidence (live bugs, cast skins, or fresh blood spots) found. This is absolutely crucial! Depending on the severity of the infestation it can take a minimum of 7-8 weeks, including repeat treatments. Failure to be thorough can prolong the process of getting rid of bed bugs and can make it harder to eliminate them.
Our place is pretty cluttered so I was freaking out. Luckily we have hardwood floors and not carpet. We tried different things. It gets really hot here, so I loaded up any nearby sheets, pillows, comforters, clothes, etc into trash bags and tied them off so nothing could get out. I put those in the car so the sun could beat heat into them all day. Never thought I’d be so thankful for Texas summers… Still got bites. We bought a mattress cover. Still got bites. We thought, okay, maybe they’re coming from the wall socket from a neighbors or something. We couldn’t close it so we kept the bed away from furniture and walls and put sticky traps on the legs. Caught NO bed bugs but STILL GOT BITES. I was losing my mind.
A cloth and hot soapy water: Like the sticky tape, a cloth with hot water can be useful for capturing bed bugs. Have a bucket of water handy and as you wipe an area, check the surface of the cloth for bed bugs and then immerse the cloth in the bucket. Wring the cloth to remove excess water; you do not need to soak the surface that you are wiping. Also, check the area that you just wiped because heat may cause hungry bed bugs to move. The cloth is particularly effective when you find a cluster or group of bed bugs. Keep in mind that wet surfaces will reduce the effectiveness of sticky tape as a trapping method.
What’s the best way to get rid of bed bugs? Stop feeding them. To prevent those unwanted dinner guests, isolate your mattress from the rest of the room. Start by pulling the bed away from the wall and away from other furniture like nightstands and chairs. Remove box spring skirting that hangs down to the floor. Oversize blankets that drape to the floor can also act as a ladder for the little buggers.
Select and use insecticides safely. There are no magic sprays that kill bed bugs very well. Most commercial insecticides will kill bed bugs if applied carefully and directly to the insects and their hiding places. An exception is “Bug bombs”, or aerosol foggers. Foggers are mostly ineffective in controlling bed bugs. Because bed bugs hide in crevices and voids where aerosols do not penetrate, they are able to avoid contact with these insecticides. Their use is not recommended. Some of the products you may find helpful include:
If the bed bugs are coming from someplace other than your bed, I’d sprinkle uncalcinated diatomaceous earth around cluttered areas and the walls, and bleach the crap out of surrounding furniture. What the diatomaceous earth does is basically attach to their exoskeleton, dehydrate the insect, and they’ll either die of dehydration or get shredded apart as they crawl. Unless your pet or kid would directly eat the diatomaceous earth, it is safe to be in contact with since it’s not a chemical pesticide and it’s fairly cheap.
People don't often consider bed bugs until they've left their mark. The appearance of flat, red welts in zigzag lines or small clusters is a key sign of bed bugs on humans. Bed bugs can also leave their bites in straight rows and, while they don't spread diseases to humans, their bites are quite irritating and scratching them can lead to bleeding and infection.
Some less proven heat weapons have been suggested online, such as clothes irons. Clothes irons might reach the temperature needed to kill bed bugs, but the heat won’t penetrate deep into soft materials to where bed bugs might be hiding. You also can’t iron areas besides clothes and sheets, like cracks and crevices in walls, floors, and furniture. The metal surface and high surface heat would damage many of the materials it wasn’t designed to be used on.
Bed bugs were mentioned in ancient Greece as early as 400 BC, and were later mentioned by Aristotle. Pliny's Natural History, first published circa AD 77 in Rome, claimed bed bugs had medicinal value in treating ailments such as snake bites and ear infections. (Belief in the medicinal use of bed bugs persisted until at least the 18th century, when Guettard recommended their use in the treatment of hysteria.)
