So my 20 gal long has Gnats like I never seen before....I put fly paper in the viv watching closely so my frogs don’t touch it and killed a huge portion of them or so I thought. I wake up this morning and it was like I never addressed the issue they are all back or reproducing quicker than anything I have ever seen. I did some searching and saw people use vinegar bowls to attract them but they seem to want to stay in the viv and not outside of it. I wanted to see how other people dealt with such an infestation inside of a viv. Maybe something i dont have to worry so much about like flypaper inside the tank...That is all i need is a frog stuck to whatever that goo is they put on that paper.
