My mother has been dealing with these invisible biting insects for five months now. They don't seem to bother my dad, just mom. They have bombed the house inside and out, torn out all carpet, got rid of all furniture, she washes daily, and cleans house over and over, they have two outfits only, sleeping on blow up mattress, and sit in camp chairs which she sprays daily. She won't let me or other family come help or see her. I have sent her all types of info and products that I have researched on line. Her doctor thinks she needs to see a Psychiatric doctor. He has never even looked at her bites. I really need some help. I believe she is close to ending her life over this and I am desperate.
