What Causes Red, Itchy And Swollen Spots On Skin Post An Insect Bite?

My 88 year old mother is being bitten by something in her house. Through process of elimination, we believe it is mites. She has had the outside and inside of the house professionally treated with insecticides. Two companies have come out - neither can find signs of any insecticides. She has been to the dermatologist twice. They gave her Ivermectin. She has taken it twice- one week apart. She is still getting bit- on upper body, mostly torso. They are red, swollen, very itchy spots. Is it possible that the insect is hosting on her and not in the house? What should she do to stop the biting?

Hi,
From history it seems that she might be having Scabies infection as there is typical site and having itching spots on torso.
Scabies parasites remains under blister spots mainly on torso.
So unless there is break in the spots and then scabicidal lotion can enter in the lesion and gives its effect.
Consult dermatologist and discuss about this.
Ok and take care.
