I need information on bird mites, please help

Hi, I am a 30 year old woman from India. No one here seems to have much information on Bird mites. I know my husband and I have a home infestation from these as we've seen them on our black pillow cases. They appear to be whitish in colour and are the size of about a dot. We called a reputed pest control company who said that they could help and sprayed our house twice. The result was that the day that our house was sprayed, the bugs bit even worse. So we gave up on the pest control company.
After much research, we now follow the following strategies Iron all our clothes, including undergarments before wearing. Iron the mattress as well as the bed linen before retiring for the day. Wash all our clothes in borax and mop our floors as well. We have also sprinkled borax on the bed mattress (in the dry form). I also spray myself with Listerine in the bathroom. Despite all this, we seem to get bitten, especially me. The crawling sensation is even worse.
I finally found an entomologist in India, but not in the same state as mine, who suggested the following:
Mix 100 ml of Chloropyrifos, DDVP and Mit 505 (a miticide) in 5 litres of water. Spray everywhere in t he house including the bed and sofa. Seal the premises. Use phosphine tablets (Cellphos) in the house and leave it sealed for at least 6 hours ideally overnight. Air out the house the next day and mop floors with disinfectant.
My question is, will all this actually help? Since catsmine seems to be a person who is aware of these critters, I could really use some kind of reassurance. If not, I do not want to try the tablets as I've read that they are poisonous to humans and possibly lethal in the wrong quantity.
