Bed bugs are a traveler's nightmare. They can be picked up in hotel rooms, leaving red itchy bumps and possibly rashes to ruin your vacation. Or even worse: If you accidentally bring them back with you, they could infect your whole house. To prevent a plague of bed bugs, here are some tips of what to check while you're on the road and how to determine the symptoms of bed bug bites.

This pair of bed bug bite photos below show the immediate (left) and next day (right) reaction after feeding a colony of bedbugs from a container in the lab. (That's why they are contained in a small circular area).  The hive-like immediate symptoms are replace by dark red rash type reaction the following day with inflammation and less severe redness radiating out to a larger area.  

During the day, bedbugs tend to hide away in furniture, floors, beds, and in wood or paper trash. They typically feed on human or animal blood at night, and most bites occur just before dawn. After taking their meal, which can last as little as three minutes, they drop off the host and crawl to a hiding place. Bedbugs can live for up to 10 months and can go without feeding for weeks.
Bed bugs are annoying insects that hide in soft, warm places like beds, couches, and clothing. These bugs feed on their hosts at night, leaving small bite marks that, though rarely dangerous, should be treated right away to prevent unwanted symptoms and potential allergic reactions. To prevent more bites in the future, you’ll need to get rid of your bed bug infestation completely.

Aerosols (D-Fense NXT, Crossfire Aerosol, or Bedlam Plus) Usage: Simply attach the plastic tip to the aerosol can. Apply as a crack and crevice or spot treatment where evidence of bed bugs occurs. This includes bed frames, box springs, inside empty dressers, clothes closets, curtain rods, hollow spaces, carpet edges, high and low wall moldings and wallpaper edges.
A variety of low-odor sprays, dusts, and aerosol insecticides help with bed bug control. People must apply these pesticides to all areas where the bugs are observed as well as hiding places or spaces where they may crawl. The pest control company can help you determine if an infested mattress can be disinfected or must be discarded. Since beds cannot readily be treated with insecticides, it's often necessary to discard infested mattresses and beds.

The Internet abounds with so-called miracle cures for bed bugs. But bed bugs are hard to get rid of, so anything that advertises an immediate solution is not accurate—it's snake oil. These "cures" have included (as reported by pest control operators who come in afterward to tackle bed bugs correctly) using bleach, ammonia and even DIY heat treatment, which carries fire risk.
Each of the following pictures of bed bug bites shows typical skin reactions to the insect's saliva. Most people  are not hypersensitive to the bites and will show no reaction at all with the exception of two small dots where the bedbug punctured the skin. Other people can develop red papular eruptions (raised inflamed areas) or in severe cases, blisters.

Bedbugs may enter your home undetected through luggage, clothing, used beds and couches, and other items. Their flattened bodies make it possible for them to fit into tiny spaces, about the width of a credit card. Bedbugs do not have nests like ants or bees, but tend to live in groups in hiding places. Their initial hiding places are typically in mattresses, box springs, bed frames, and headboards where they have easy access to people to bite in the night.
