Cockroaches are naturally attracted to dark, warm, moist, and secluded areas. They’ll also sneak into food boxes or even toiletries. Like bed bugs, they will stay perfectly still after they find a good hiding place. Roaches can survive for an extended period of time without food or water. They’re also great climbers and can cling to surprisingly sheer surfaces.
Roaches can work their way into nearly any open container you leave out for them. Food packages, suitcases, clothing bags, purses, and even computer bags are all fair game. A roach can survive a surprisingly long trip until you take it back home. To avoid this, keep all travel bags closed, sealed, and elevated whenever you’re not using them. Don’t transport food with you–especially not without a proper container. If you keep your bags locked down, roaches won’t be able to come home with you.
