It also helps to straighten carpet fibers, enabling insecticides to penetrate more effectively. After cleaning, take the vacuum outside and remove and discard the bag because fleas can sometimes crawl out of the vacuum. With people and pets out of the house and vacuuming completed, an indoor insecticide application can be made. Many products are available. Flea bombs are perhaps the easiest method, but they are not very effective or efficient because they release insecticide all over the room, not just where the fleas are located.
Spot treatments with sprays directed to the floor areas are usually more effective.
When treating, make the application to the areas pets frequent. Spot-treat carpets, floor edges and cracks and under furniture near pet areas. It is not necessary to treat the entire carpet or all floor areas. If your pet has access to furniture, treat under the cushions, not on top. After treatment, do not touch treated areas until they are completely dry.
