Our son is presently living with us, and has his 10 year old son every other week-end. DGS has a skin condition anyway, but now that he sleeps in the bedroom where my aviary is, along with a big cage of 6 cocktiels, he has broken out in a terrible itching condition. Started out as hives, the first time, and then has just went to big itchy bite like things. His mom took him to the doctor Monday and he has according to them, an allergic reaction to fleas or mites. We don't have fleas, I know, but even with hanging those round metal parasite killers (and I have a lot of them, because these are big cages) what else can I do to kill anything else. I feel terrible about it, makes me feel like I am not cleaning like I should; but none of the rest of the family, including our 10 year old DS who sleeps in the same room has any issues . . .any suggestions? Something cheap and safe would sure be nice. I clean the cages faithfully ever week; but you can't use anything caustic because they chew and knaw on stuff and I love them and want to keep them safe too. One other thing I should mention, is our 10 year old had strep throat twice this year, and he broke out on his arms and other areas with welts and then they itched to the point where he had small scabs . . . so off to the doctor we went and I told the PA, who is VERY good, about having the birds in the room with him, and she said no, that wasn't caused by birds. . .she even had the MD come in and take a look and said it was acute dermititis and gave us a steroid cream to use and its fine now . . .only had to use it four times and it cleared completely up. I thought the itch/rash might have been from strep, because you don't have to have a sore throat to still have it, so wanted to make sure.
