        @Sarah: I’ve heard/ read that Diatamaceous Earth is a cheap, inexpensive way to rid your place of bed bugs & that the Pest Control companies don’t really want people to know about it.. (of course, DIY is less $$ in THEIR pockets!) You can get this @ Feed supply type stores and it MUST be Food Grade diatamaceous earth. Food grade will not be harmful to any living mammals, including pets. It is like a powder and you sprinkle it (lightly) wherever.. when bed bugs walk thru it, it acts like little razors to them… and they die. Just keep in mind, D E does not work effectively in Dampness/ damp areas, so if applied in a damp environment it must be re-appled -dry. Hope this helps. YOu could probably get other opinions, etc on Diatamaceous Earth & bed bugs if you Google it. Right now, i am in a new (2mos) Apt.. & have heard that my downstairs neighbor has Bed Bugs really bad..The rental agent tells me there will be an Exterminator/Pest Co. here next week too inspect whole Bldg. (6units per Bldg).. I’ll keep u posted what transpires.

    Am very angry….never bee exposed to these in my life untill I stayed in a hotel that looked clean enough to me but man was I wrong…me and my children are covered in bites yet my boyfriend has none and sleeps right beside me….I pick and say my blood is sweeter but why is he really unbothered by them

    • Desiree says:

      @maranda: This may be a little late to say but it’s probably an allergic reaction. You may be Allegergic and your kids may have gotten that from you. While your boyfriend was probably bitten, it may not have appeared on him because it’s so hard to spot if you aren’t reacting to it. I’m no expert by any means but it seems the most plausable because bites usually don’t show up so soon if you aren’t allergic.

      @maranda: I slept in my brothers bed while he was on holiday, and I got bitten, not too badly, just a few here and there. My mother said she had sorted the problem, and a few weeks later (against my better judgement) I slept there again…. Ouch!!! I was very badly bitten :/ the difference (and this will answer your question) is that I had shaved my entire body inbetween, mens hair makes it harder for the bugs to get to your skin.

    My son had bites that occured on his arm, legs, and groin area. We did not know what they were. He later had his lymph node to swell underneath his arm. I took him in and he was told he had an infection due to the bed bug bites. They gave him a shot and some meds to take. He is still itching! What do I need to do next. Articles say they should last 2 to 3 days. These bumps have been itching for over a month.

    bed bugs have nothing to do with being a dirty or clean place. They get to hotels and stores by hitching rides on people. For example if i have bed bugs and i buy a shirt and take it home with me and then decide to take it back and some of the bugs hitch a ride the store hangs it back on the rack and then you try it on boome you have bed bugs or people who travel to different hotels carry them from place to place

    Bed bugs are extremely hard to get rid of because they don’t eat anything but human blood, so you can’t poison them orally, and the only effective poisons are the ones each bug has to come into contact with. Over the counter poisons will give them a tolerance, and even the pros can overlook the many, many little places these things can hide. You have to use yourself as bait. A good thing to know is that they stay 5 to 20 feet from you – Close enough for easy access and far enough away to be safe from killing them when you are awake. The young ones are translucent and small enough to hide in the smallest of cracks. Best to circle your bed with poison. They feed every 3-4 days but can live for a year without food. I’ve also learned from experience that if a treatment does not work in 2 weeks, you need a follow-up treatment – no matter what the exterminator says about a 30-45 day residual from the poison. If they haven’t stepped in it and died in two weeks, it isn’t going to happen. There is either a gap in the poison circle or the poison has lost enough strength to kill them. It takes a while for them to die because first they have to cycle out (some may have just eaten and need 4 more days to come out again), and then allow another five days or so for them to actually die. Hence why it takes a couple of weeks, but no more than that.
