OUTDOORS! In the yard, on the lawn, in your garden, underneath your deck.
Nematodes and fleas have co-evolved for millions of years – they have the same habitat preferences. Focus on areas that are shady, moist, sandy, and places where there is a lot of animal traffic. Along fence lines, your dog’s favorite shady patch in the backyard, underneath your deck where wild possums might try to make their nests…
Inside? Not unless you want soggy carpets! Nematodes move through the soil.
On my pet? Not unless you like the smell of wet fur! You could try, because nematodes are completely harmless to your pets, but they need about 24 hours to find and infect fleas. Once your dog dries off, the nematodes would stop searching for fleas.
