To prevent bringing home<unk> s, travelers are advised to take precautions after visiting an infested site: generally, these include checking shoes on leaving the site, changing clothes outside the house before entering, and putting the used clothes in a clothes dryer outside the house. When visiting a new lodging, it is advised to check the<unk>  before taking suitcases into the sleeping area, and putting the suitcase on a raised stand to make<unk> s less likely to crawl in. An extreme measure would be putting the suitcase in the tub. Clothes should be hung up or left in the suitcase, and never left on the floor. Additional preventative measures include sealing cracks and crevices (which are often the sites of<unk>  harborages), inspecting furniture, and for exposed travelers to decontaminate clothes and luggage upon returning home. The founder of a company dedicated to<unk>  extermination said that 5% of hotel rooms he books into were infested. He advised people never to sit down on public transport; check office chairs, plane seats, and hotel mattresses; and monitor and vacuum home<unk> s once a month. Close all wall openings or gaps;<unk> s tend to hide in dark places and cracked walls are a perfect spot for them to infest.
