Might bed bugs detect pesticide and spread?(3 posts)
Wow. This has gone on way too long.
I'll begin with my question, then give back ground.
We'd like to spray the Premethrin along the walls of all the rooms in order to try to control the bed bugs. We've already attacked one room by heating/steaming/spraying the premethrin twice (weeks apart)/coating the floors with sealer.
The bugs have, of course, exited that room and we cannot find where they are. We'd like to spray the Premethrin tonight, then follow with DE in a couple of days. My fear is that the bed bugs will detect the premethrin and stay clear of the walls and find a new place. Do they do that?
Now for some back ground and perhaps you will offer advice:
About nine months ago a friend left two adult bed bugs on our couch. Such is life. We looked and looked for more. Tore apart the couch. We WERE bit- but could find nothing. First time my son and I were bit we both had normal reactions, but the second time, a week a part, we both had severe reactions: easily visible were raised, angry red inflammed lines indicating that the reaction entered our blood system - antibiotics prescribed... We were warned by the doctor that our systems might respond with welts that appear to be bites but are the continued reaction from the bed bug allergy in our system. Great. Months later - one of my sons complained of bites whenever he slept in his older brother's bed - older son has no reaction, nor does my husband. BUT still we could not find any bed bugs. Two exterminators - twice - did not find any, but did suggest we hire their dog services for $300.
Then the day before Thanksgiving I wake up with, easily, twenty bites. Nothing, as usual, could stop the itching, and, as usual, each bite had a four inch swelling, itchy welt surrounding it within 24 hours. Atarax, Benadryl, etc - didn't touch the itching. Put on predinsone. Not only did it not releave the itching, I began to itch ALL over, even where there were no bites - bottoms off feet, palms, etc. I had slept in my son's room - The Bed Bug Room - one night when I was restless and no one else was in there. So - called in the exterminators again. No bed bugs found but another offer to bring in the dogs at $300 each. We find, on the ceiling, the little black spots. Bed Bug Poops. We had stripped the bed and put double sided tape on the mattress and the floor - we found them. Two young bugs caught on the tape. Mainly eggs, very few encasements, on the bottom of the box spring. Along the windowsill we found one live one and another batch of black spots. So - lots of black spots, all together maybe four bugs - none appeared to be full grown, and very few encasements.
My fear is that they are actually living elsewhere. The black spots revealed no nearby encasements, feces or live bugs. We sprayed the moldings - ceiling and floor - windowsills, bed frame - discarded the mattress and box spring - they were old and due to be replaced. We were told that the premethrin would kill them - put in GENTROL which sterilizes them if I recall correctly - as they walked through it. Two weeks later - I have another bite in my own bedroom. Move out of that room. Husband still there - so they have a meal if they wish. So two months - still have not seen any in my bedroom. I've been sleeping in the guest room. two weeks later - another bite. Can't find any bed bugs. Doctor suspects it is the phantom bite due to the bed bug 'poison' still in my system. It's been a month. I'm JUSt starting to sleep better. Yesterday my son wakes up with five bites.
So - again- we want to put the premethrin - of which we have two gallons - around the perimeter of the rooms. Rather than kill them - might the little monstors detect the poison and go elsewhere?
We are just baffled that it takes until there is a large infestation to find these creeps. My husband and myself, friends and exterminators have examined my rooms with strong led flashlights - and tweezers at the ready - and found nothing until all of a sudden we had this infestation. According to the Cornell Cooperative experts, we were told that we actually caught it rather early - hence only eggs and very few encasements and actual bugs (has to do with their cycles and ability to nap well and long between available meals.)
Especially since we have hundreds if not thousands of books, lots of hobbies.... a professional company would charge a normal house $5,000 and we were told even more for our home. It's just not feasible. AND even they can't find them! So, keep the advise coming.... Thank you....
Products can be either non-repellent or repellent. For bed bugs the goal is complete elimination and not just control and so it is best to use non-repellents so they will also to through it. Whatever you put down do a little research on and find out what type it is.
Any update? I'm very interested in your case. Have you thought of putting down bed bug interceptors on the legs of the beds? I know it sucks, but I actually wish I had reactions like you do. It is very hard for me to tell if we have any darn bugs left because no one in my household reacts to the bites.
As for the main question... I read a q and a research article once where a college expert was asked if bed bugs can detect and will avoid insecticides, and he said from his research, he concluded that they can detect it, but at the same time they won't avoid walking through it if it means getting to their nesting site, or harborage. I'm guessing this means they'll avoid walking through it to get to a meal, though, and would rather wait until it wears off, but don't quote me on that.
