That's very possible. I have heard of couples reporting that only one partner is getting bitten. The truth is that both are getting bitten, but only one has a reaction to the bites. Thirty percent of people or more don't react to bed bug bites at all, and the elderly are less reactive than the rest of the population. Among those people who do react to the bites, most of them don't respond to early bites, but develop a sensitivity to subsequent ones. Those individuals who are not sensitive to bed bug bites may not know they have an infestation. Because bed bugs are nocturnally active, it's hard to see other signs of their presence—unless you're accustomed to waking up at 3 A.M. and taking a census. With a huge infestation, bed bugs start to move away from the bed, so you're more likely to see one in an exposed place during the day. In very severe infestations people can become anemic. That takes a lot of bugs though—maybe 100,000 feeding once a week or more.
Three days after the initial “feeding” the sores hurt really bad. They itch like no other. By the way, none of my roommates have experienced this. I started panicking and washed all my clothes and sheets. I checked every corner of my room. Nothing. I couldn’t find anything, so them things must be hiding pretty well. Unless it isn’t bedbugs. Today I woke up and realized I had three more bites on my arm just above my elbow in the “breakfast, lunch, and dinner” pattern this site talks about.
Thanks so much to the person who mentioned the hot/cold water method! I think when you do it when you first notice the bites, It will keep them from becoming huge, itchy welts! I run hot water over the bites and I feel a sense of relief, as if I’m scratching the bite, without actually scratching it. The area turns pink, and I keep going until the relief sensation has subsided, then I run cold water over the area. Works great and it does last for hours!
The life cycle stages of a bed bug are egg, nymph, and adult. The reason they are called bed bugs is that they readily infest mattresses, bed frames and box springs. Eggs are laid along the edges of or around buttons on the mattresses. Eggs can also be glued to rough surfaces. Bed bug females lay about 200 eggs, usually at the rate of three or four a day. Eggs are placed in cracks, crevices and other isolated and protected shelters. Females lay eggs after a blood meal. Eggs will hatch in one or two weeks into Nymphs. Newly hatched bugs (Nymphs) begin feeding immediately. At room temperature, and with an available food supply, the nymphal period will last 14 to 30 days. They shed their skin (Instar) five times before becoming adults. Bed bugs will mate soon after becoming mature, so the time from egg hatch to egg laying is 4 to 9 weeks, under favorable conditions. The average life span of the bed bug is 6-12 months and they feed every 10 days or so during this time. Bed bugs can survive many months without a blood meal and their reproduction is high.
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.
