How To: Clean a Roach Colony

[JeffreH]

You can also use the drink carriers at fast food joints; they aren't as efficient as the egg flats but they are very easily onbtainable and free. Taco bell usually stacks them up to the ceiling so snooping a few here and there with the occasional trip makes for decent roach furnishings.

The same principle may apply for egg flats. Some fast food locations and restaurants that use eggs in their dishes often pitch their egg flats (like Bob Evans). You can try asking or calling ahead of time and see they'll set aside what they use for the day for you to pick up for free.

Those are a couple of the cheaper/free options = )
