What to do with extra hissing cockroaches?

[NitroHydroRay]

I have a lot of hissing cockroaches because my colony continues to breed. I'm 18 and will be going off to college next year, and while my parents are willing to take care of my roaches while I'm gone, they don't want the colony to continue growing. How do you deal with over-population? I'm open to euthanasia if there's an ethical way to do it. Thanks

Sell em in bulk for cheap as feeder use. That's what I do to cull overpopulated colonies.

Where do you find people to sell them to?

Here on the forums, on facebook, heck I've even had luck using Craigslist.
