How long will it take to get a flea problem solved?

Adult fleas are usually killed fairly quickly, while newly developing fleas in the environment surrounding your pet, may delay complete flea control. If you currently have infestations on your pet and in your home, it may take approximately 2 to 3 weeks after the initial application before you see complete flea eradication. You may need to treat your home after 2 weeks, to kill new adult fleas as they emerge from their protective pupal cocoons.
