I had the little red ones. I had my best luck with Vapona strips. I don't know if I really would reccomend them because of their unhelthy aspect but they did kill the spicer mites. I still use them but my wife and I haven't died yet.
i buy the hot shots brand , same ingredients , slighty higher in one but hardly at all , and can be bought at hardware stores , canadian tire , wallmart , ect ect
hell i have 5 hanging in my basement and 1 in my living room , 1 in my pc room , 1 in my kitchen , and one in the 5X10 tent in my master bedroom where i sleep
ive been useing them for about 3 years , i replace one then sometime/whenever possible i replace another ect ect and i havent died yet
i truely believe and praise them for being what finally rid me of mites after a year+ battle and trying EVERYTHING i could get my hands on
i do not however believe they are good for up to 4 months as advertized , bellow ill give my experience and advice when/for useing them ,,,,,,
when i first put ONE up it was in the basement , the fruit flies were loving the empty beer cans and breeding like rabbits on V , these strips are so powerful it not only killed the flies in the basement but every damn fly upstairs as well , as time went on i started to realize flies would land on them even when they were only weeks and even days old , hence the reason i do not believe they are good for 4 months
now then, when i finally killed the mites i took this new found information and bought multiple strips , opening one every 2-3 days , to my extream excitment a week later i could not find one single mite , and to this day (approx 2 years later) i am still mite free
peace
