A crackdown on rubbish is being launched in Leicester to try to rid the city of rats. The city council received about 4,000 calls about rats and mice last year and has closed 40 food outlets in the past 10 months because of rodents.
Posters featuring giant rats are being put up around the city to warn people against dropping rubbish.
The two-week poster campaign also warns people they face �50 fines for littering in the city.
Malcolm Grange, head of environmental health, said: "Rats are one of the most serious rodent pests in the world, carrying diseases such as leptospirosis, salmonellosis and campylobacter.
"Rats eat food debris from the floor and rubbish that is not placed into sealed bins, so it is important to encourage everyone to do their bit to keep pests like this at bay by putting their litter in a bin."
