The borax sucked up into the vacuum will handle the bugs inside the bag. Apply two times a year and you should be flea-free forever. To keep pets from being infested in the yard, spray beneficial nematodes early each summer. They are still available until August. Spray them in irrigated parts of your yard. The nematodes are tiny worms which attack fleas and 200 other underground pests, including grubs (beetle larva), and subterranean termites. After a couple years you should have a healthy population of nematodes and can discontinue spraying. Beneficial nematodes are available at Walter Anderson Nursery, Andersen's La Costa Nursery, Grangetto's Farm and Garden Supply, Simpson's Nursery, and many other good nurseries. Pet Flea Rinse The peel of two large lemons One quart of water Boil the lemon peels in the water for 10 minutes in a covered pot. Let stand until cool. Sponge the resulting "tea" on your pet and allow it to sit for an hour. Rinse off. Repeat weekly if needed. (Just like people, animals ? especially cats ? can have allergies to lemons or any food item. If your pet starts shaking, vomiting or showing any unusual reaction to the lemon solution, wash the solution off right away with a good shampoo. If symptoms persists or worsen after washing, consult a veterinarian immediately.)
