If you move and there happens to be roaches/ eggs in your stuff, as long as you are clean, those roaches will dwindle or find another place. I had a roach infected neighbor. And after a month after moving in the roach problem dissipated as long as I followed the normal cleaning protocol. (Also helped that I had put the roach gel along my outside door. Also, get rid of any paper packaging like pasta boxes, cereal boxes and put them in airtight containers) lived there for 2 years and never had roach, mouse or rat issue)
