I thought I was getting bitten by mosquitoes when out on my balcony. But I get bitten during the night and basically on the arm outside of the covers. This all started after my neighbors in the apartment next door moved out. I have yet to actually see the bugs. The bites tend to be in a line which I read online was typical for bedbugs but not always.

When traveling, inspect the bedding prior to exposing yourself or your belongings. Seal your dirty clothes in plastic bags. You may even consider encasing your luggage in a plastic bag while you are in a hotel room. Launder your clothing as soon as you get home. You can treat your suitcase by vacuuming, using a clothes steamer, or handwashing it with hot water and soap. You might also consider encasing luggage in a plastic bag between trips.
2. Active Guard Liners: Active Guard Mattress Liners may be placed on beds and are effective as both preventative and active bed bug treatments. They kill bed bugs and dust mites within 72 hours and will prevent bed bugs from infesting mattresses. ActiveGuard Liners act like a fitted sheet; it comes in single, full, queen, and king sizes that fit up to 17" in depth.
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.

I know this is a few years late, but I just wanted to let you know we had a similar situation, but it was for a few months every summer. Turns out there were bats in our attic, and the bat bugs will still bite you like bed bugs except they don’t really love humans so it will be infrequent and you won’t have to worry about an infestation! When you get rid of the bats, they go away eventually.

Cutaneous reactions to bedbug bites can vary widely and are easily confused with other conditions (Table 1).15–19 A typical lesion is a 2- to 20-mm, pruritic, erythematous maculopapule with a central hemorrhagic crust or vesicle.5,8 Macules, papules, wheals (Figure 3), vesicles, bullae, and nodules have all been reported,20 as have asymptomatic lesions with a barely visible punctum as the only evidence of a bite.8 Bites vary in number and are preferentially distributed in unclothed areas (e.g., face, neck, extremities). Unlike many other arthropod and insect bites, bedbug bites are rarely located in the popliteal fossae or axillae.21 Lesions can be noticeable immediately when waking up or several days later, with the reaction often progressing from delayed to immediate with subsequent exposures22–26  (Table 2). The classic bedbug rash is referred to as “breakfast, lunch, and dinner” because it commonly presents as several bites in a row or cluster 20 (Figure 4).
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.
