Hi! I was just curious, I am staying at my parents (which Ive never had an issue before) and have 21 bites on my bicep/forearm/in the bend of my arm which I noticed yesterday. They dont itch and are already losing the redness. This morning I woke up and have no new bites. My husband and son do not have bites either (they both are very sensitive to insect bites too). We checked the bed before bed last night and there were no signs of bed bugs. Is it possible that its still bed bugs???
Some people have no reaction whatsoever to bed bugs. In addition to not having much of an effect on the elderly, some are just not allergic. Since the irritation and welting appears as the result of an allergic reaction, it is possible to not even know that you were bitten at all. It is entirely possible for several people to live in the same house, and have one person not be affected.
These bugs are extremely sensitive to heat in every stage of their life. Thermal death point of a common bed bug is just 111°F to 113°F. Many times even temperatures that are lower than this, 97°F to 99° F can kill multitudes. If the temperature is raised to 140° F for about an hour or to 120°F for several hours most infestations will be eradicated.
It is also recommended to put infested items, such as a mattress, in a sauna that reaches temperatures of upwards of 170° Fahrenheit. Similarly, they also perish in extremely cold temperatures so mattresses and other items can be cleansed of these bugs with the use of plastic wrap and dry ice. Cover the items with large plastic tarps and carefully insert dry ice, and then secure. The extreme temperature will naturally fumigate the pests.
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.
First, there should be a thorough inspection of areas that may be infested to identify bedbugs. Once a room is identified as infested, don't remove anything from the room unless it is sealed in a plastic bag. Furniture and items that you want to discard rather than treat should be bagged and destroyed so other people don't use them. Call your trash collection agency to arrange for an immediate pickup. Reduce the clutter in the room and discard any cardboard boxes as they can harbor bedbugs. Vacuum the area and seal the vacuum bag in a plastic bag and discard it.
Spray all baseboards, loose plaster, behind bed frames and headboards, beneath beds and furniture, and bedsprings and bed frames. Do not apply to furniture surfaces or mattresses where people will be laying or sitting unless using a product labeled for that type of treatment. Infested bedding should not be treated, but should be removed, placed in sealed plastic bags, and taken for laundering and drying at high temperature.
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.
