bug problem

[-okapi-]

I have a small problem. Well the problem IS small but theres about 3 MILLION of them. My house is infested with fruit flies. Some how a few discovered the wonderful world of my iguana's food bowl and started to breed. Every day for like a week i would dump the leftover food from the day before in a garbage can next to my iguana's cage and replace it with fresh food. It seems the eggs in the garbage hatched, grew up, and multiplied. Now every time i go to feed zig theres a swarm of fruit flies that covers her food. even if i dump the old food outside theres still some way that they are multiplying. Any good ideas on how to get rid of these pests? I dont wanna "bomb" the house because i breed beetles and crickets. I really dont like pest strips and have heard reports of them causing problems with reptiles. I hope that soon they just get so inbred that they die out (which ive heard is a problem after a few months of inbreeding for people who try and breed them on purpose).
