The warm and wet winter has proved the perfect conditions for fleas and there has been a 50% in call-outs to deal with infestations. Fleas typically live outside but are carried into homes by pets or people, particularly those who have come into contact with wildlife such as foxes, rabbits, rodents or deer. Once they are inside, centrally-heated homes with carpets and upholstered furniture offer them prime conditions in which to prosper. The most common indication of a flea issue is skin irritation. Fleas most often bite people around the legs and ankles, which can be sore for several days. Fleas found on your dog or cat represents just 5% of the total flea population nearby. The other 95% will be in bedding, carpets and furniture. Fleas can lie dormant for months at a time.
