There was a few in the food cupboards I cleaned them out and had none since but I've just found one upstairs while cleaning

THere are lots of bugs that might infest houses... perhaps a location (Country and state or Province) as well as a better description of how big they are exactly and what they look like or even better a photo would go a long way in assisting in getting you the correct answer.

Am in the UK, their no bigger than a grain of rice seem to move really slowly they are brownish and white can't seem to find out what they are and they don't crawl seem to slither please help
