You may be providing too much of a potentially toxic chemical if you use, say, a flea dip and a fogger with the same chemical ingredient. Always check with your veterinarian before beginning your war on fleas. If yours is an outside pet, you'll need to tackle the yard, too. Sunlight kills fleas, so concentrate your efforts in the shady areas of your yard especially. You can spray your yard with insecticide, or you can battle fleas with their natural enemy, nematodes.
Nematodes are microscopic worms that kill flea larvae and cocoons.
Apply them to your yard once a month until the fleas are gone. Check with your veterinarian or your pet supply or garden stores to find out more. Flea control has reached new levels in recent years. Today, there are products on the market that you can treat your pet with once a month that will help keep those annoying little jumpers away. Insect growth regulators, or IGRs, are safe and act like flea hormones to interrupt the life cycle of the flea, preventing them from maturing into adult fleas.
