I bought a GQF cabinet incubator (2001 yr?) on CL yesterday. It has the acyrilic door, automatic egg turner, and some other things that I have no idea how to use. SOOOO, my problem is, that when I was looking to see if I could figure out what model it is I saw movement. LOTS of those tiny kitchen roaches!!! Let me just say I am deathly terrified of roaches! So I sprayed bug spray in it and my husband moved it outside. My question is...What is the silver cardboard stuff underneath the incubator (on the outside)? I know there are more roaches hiding in that stuff and I want to replace it. PLEASE HELP!!! Otherwise I don't know that it will ever get used if I can't irradicate the problem. Thanks!
