Kitchens Kitchens are a goldmine for these tiny little creatures. Between the food crumbs, high moisture levels from cooking and dishwashing, and all the hidden nooks and crannies, it’s an excellent environment for them. If you’ve got a pantry that’s less than immaculate, Silverfish might be setting up camp in there too. 3.
