We just purchased this spray in one of the pet shop around hongkong as they do not sell evermectil. They guys there told us that this is much better for flea and mites.is there anyone who had use this product before? I cannot find a review and I would like to see comments first before we used them to our two piggies. Many thanksmfor your assistance, very appreciated for aything as being here in macau it is really hard to find stuffs for the babies. X
