Individual responses to bites vary, ranging from no visible effect (in about 20–70%), to small macular spots, to prominent wheals and bullae formations along with intense itching that may last several days. The bites often occur in a line. A central spot of bleeding may also occur due to the release of anticoagulants in the bug's saliva.
In the case of beds, a more economical option is to encase both the mattress and box spring in a protective cover like those used for allergy relief. Encasements specifically designed to help protect against bed bugs are available through retail or pest control firms. Higher quality ones tend to be more durable and comfortable to sleep on. Once the encasement is installed and zipped shut, any bugs which happen to be inside are entombed and eventually will die. Encasements also help protect newly purchased beds, and make it easier to spot and destroy any bugs residing on the outer surface during subsequent examination. Encasements will not, however, keep bed bugs from crawling onto a bed and biting a sleeping person.
Great stuff to use. My former girlfriend gave me a parting gift of bedbugs she got while staying at her parents house. She was good enough to leave me some cortisone though which I needed for the first time this morning. I had being seeing bedbugs and routinely treating them for about 2 months and I had laid diatomaceaous earth around my bed and didn’t have any itching or real issues. The layer had been wearing thin and I was too lazy to respreads. Last night I slept in the nude and woke up with the worst itching and now a rash all over my body. I had been seeing bedbugs and killing them for a month or two on and off and thought what’s the big deal. Now if know!!! This is the worst case of itching I’ve ever experienced!! Luckily I have the cortisone but it’s not helping too much. I’m blasting off a bed bug bomb my brother gave me 2 months ago that I never used and respreading the diamo earth. I checked my mattress and found literally only 2 bugs a very small nymph and an adult but they must be somewhere else because my body is covered in a rash. Maybe I finally reacted to bites I had been getting in the past or more are hiding elsewhere but I’m going to rid myself of these pests. Wish I could rid the world of them!!! This itching is the worst!!
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.
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.
