I have had my bunny, Caddy for 3 years and for the past year (after we moved to a new apt) I have had gnats in his cage. I cannot for the life of me get rid of them and I don't know what to do. I have done everything; vinegar, fly strips, changing more freq, i even tried cedar shavings from my aspen that I usually use to try to repel them. I am out of ideas!! Please help!!
