So for the first time since I have moved to SF (5 years ago) from South Carolina I have not seen a single mosquito (Thank god because that was getting old.) All of a sudden starting last week I have killed 6 of them and they have been eating us alive. We keep a window open in our room so the tanks can get oxygen. Their is a screen in place, but I made the screen and it isn't exactly professional (small gaps on the corner of the screen due to improper measurements plus we have a portable AC unit attached to our window which also allows stuff to come in time to time). Anyone have a SAFE way of keeping these things at bay that won't bring harm to our fish tanks? I really didn't want to spay chemicals in fear that it would bring detrimental effects to our fish tanks.
