Bed bugs are obligatory bloodsucking. They have mouth parts that saw through the skin, and inject saliva with anticoagulants and painkillers. Sensitivity of humans varies from extreme allergic reaction to no reaction at all (about 20%). The bite usually produces a swelling with no red spot, but when many bugs feed on a small area, reddish spots may appear after the swelling subsides. Bedbugs prefer exposed skin, preferably the face, neck, and arms of a sleeping person.
In the lab we handle all the bed bugs in a specific room that we steam clean once a week, and we have double-stick tape barriers that they can't walk through (as long as the adhesive remains dust-free). And the bed bugs themselves are enclosed in containers that they can't get out of. We actually feed them inside those containers—we lay a blood reservoir against the cloth "lid" and the bed bugs have to push their mouthparts through the cloth into the reservoir to eat.
Every morning, even after countless treatments of our bed and linens, I wake up with 20-30 new bites. I react extremely strongly to them, they can swell as big as a half dollar, and they itch sO badly I often end up ripping them open, leaving them prone to infection. I’m now a diagnoses anemic, which the doctor is sure is because of the number of bites…they are literally eating me alive…and killing me.
DIY approaches come with risk. It's not uncommon for someone to use a pest-control bomb or fogger that is available over the counter. These don't work well against bed bugs, according to research from Ohio State University. They can also expose people to toxic chemicals. Neither are over-the-counter aerosol insecticides effective against bed bugs. Most of these products have either pyrethrin or a pyrethroid as a main ingredient and those compounds have the same mode of action as DDT, which bed bugs have become resistant to. If you spray the bug directly you might kill it, but that is not going to get rid of the infestation. The problem is finding all the bed bugs. Some just can't be reached with insecticide. It's difficult for nonprofessionals to do anything more than kill what they can see, but that's just the tip of the iceberg in terms of what's there.
You should look for traces of the insects in the folds of your mattresses, box springs and other places where they are likely to hide. You might be able to find their papery skins, which get cast off after molting and look like popcorn kernels but are smaller and thinner, Harlan said. They also leave small, dark-colored spots from the blood-filled droppings they deposit on mattresses and furniture. If you can touch the spot with a water-soaked towel and it runs a rusty, reddish color, you're probably looking at a fresh drop of bedbug feces, Harlan said.
Bedbugs are a species of insect known as cimex lectularius (literallycimex is Latin for bug and lactularius is Latin for bed). There is a second common species of bedbugs known as cimex hemiptera. These are known as the tropical bedbugs, staying within 30 degrees of the equator. There are published reports, many without supporting evidence, that each of the common bedbug species has chemically different saliva. Some researchers, however, have found no difference in the reactions caused by each species.
The next sign is that the bites will occur nightly while sleeping and the rashes will increase daily. These rashes will usually be located on the legs, arms, neck, face and back, which are the most common areas. The reason these places are the most common sites is because these areas are usually exposed during the night. Exposed areas of the host are what they prefer.
We took extreme measures and hired a Heat company to come in. They heat your house to approx 150 degrees (internal wall temp of 140 or more). Bed bugs can survive for 7 minutes at 115 degrees. The heat company heats your house to well above that temp and maintains it for 4 hours! It was great!!!! We have not seen a bed bug since…except for dead ones!! I will warn everyone…the treatment is not cheap. We have a 3200 sq foot house that is only 2 years old…the cost was $4000. They base the cost on square footage, age of home, insulation, etc. I freaked when I heard the estimate, but worth the money to be rid of them!!
To prevent bringing bed bugs to one's own home, travelers are advised to take precautions after visiting an infested site: generally, these include checking shoes on leaving the site, changing clothes in a garage before returning to their home, and putting the used clothes in a clothes dryer outside the house. When visiting a new lodging, it is advised to check the bed before taking suitcases into the sleeping area and putting the suitcase on a raised stand to make bedbugs less able to crawl in. "An extreme measure would be putting the suitcase in the tub." Clothes should be hung up or left in the suitcase, and never left on the floor.  The founder of a company dedicated to bedbug extermination said that 5% of hotel rooms he books into were infested. He advised people never to sit down on public transport; check office chairs, plane seats and hotel mattresses, and monitor and vacuum home beds once a month.
Hi there! Honestly, if you have checked properly (like really well) and you don’t see any signs of bed bugs, it might be another insect. Unfortunately, there are so many little insects that could be biting you (such as fleas, etc.) but maybe start with giving all your laundry a good hot wash. Once that is done, see if you continue getting the bites and then we can investigate. Good luck, if you appreciated my help, please share my blog with your friends and family.
Bed bug bites occur most frequently while you’re asleep. As bed bugs bite they inject their victims with an anesthetic (as well as an anticoagulant), numbing the area and making it very rare for someone to wake up when bitten. Bites normally take a day or two to appear, although depending on your individual reaction they may be more visible sooner.
Most bites will have a small clear area in the center surrounded by redness that may or may not be raised. People tend to become more sensitive and have larger reactions after each episode. Reactions can include itch, swelling, rash and wheals (large round red area on the skin). Severe reactions can cause skin blisters and trouble breathing, although these reactions are very rare.
