Dryden says the pill is 200 times safer for animals than insecticides and has been approved for use in 35 countries. Program won't kill adult fleas already living on the pet. And it won't prevent the pet from being bitten by a new flea that hops on the animal. Fleas are blood suckers that will cause your pet to itch and maybe get a skin infection. Not only do pets itch when they get fleas, they also shed flakes of flea dirt, which is the dried blood left behind by the fleas.
Some pets are allergic to flea saliva.
Dryden said an effective flea program treats the infested pet, all contact animals and the environment. To get rid of fleas, vacuum the carpet before applying insecticides and discard the vacuum cleaner bag immediately. Dryden suggests treating carpets with insect growth regulators like fenoxycarb or methoprene, which can protect the area from fleas for up to a year and a half. A methoprene product available at many pet supply stores is a collar that prevents flea births. Therefore, the environment must be treated with flea sprays to control adult fleas.
