hey im in toronto and there are a few mite sprays you can get here, i had a mite problem a while back and i just used a ivory soap and water mix. . . i made them a bath in my bath tub, with a few drops of ivory soap make sure the water isnt above 85F . . . after they had a good soak i would take them out individually rub them down with a towel then go over them with a little tool to pic the mites from under their scales and in their heat sensors, also if you notice they might have some in their eye area i used a q-tip to rub gently over the eye area to get the mites out.
also while they were soaking i would clean their rubbermaids to make sure to get any mites and eggs left behind, i find that if take the rubbermaids outside and use a blow dryer the mites will die becuase the hair dryer is too much heat for them to handle and eventually they cook and fall off the rubbermaids....
hope this helps!!! . . . it worked for me takes 1-2 weeks to get rid of them all, mites are a pain in the ass
