>>19050846>All cockroaches have wings.I thought only some very specific kinds had them since they rarely fly, but after looking it up, it turns out that's true.
>Cockroach-proofYeah, sort of.
The best thing you can do is to not leave any bits of food out and keep your house clean and dry.
Also caulk any cracks and gaps to keep them out, though they're so small they could slip under the door if it's not low enough to the ground.
Basically just standard pest prevention.
