before they molt to adults?
Ans: Mariele, Since this is an important issue for cockroach biologists I constructed a page to explain it as I understand it from Mary Ross and Don Cochran, and have used this technique for decades. It is almost fool-proof: Sexing Blattella nymphs Q64: Karna and Izzy and Sarah ask: … we are moving. And we have a problem with big huge roaches in our house, mainly kitchen and bathroom. I am VERY worried that during packing and moving the roaches will jump into my suitcases and nest in my clothes!!!!! Ans: K, I and S, What can I tell you? Cockroach larvae will hide anywhere they can. Moving with migrating human populations is exactly how pest roaches have gotten around the world. I have no magic solution. Kill the roaches any way you can before you reach your new home. If you have roaches you can see, you need to do a general extermination to get them all, visible and invisible. Fumigate the moving van? I am not an exterminator and have no special expertise in that respect.
