Flea bombs come in a variety of sizes depending on the brand and chemicals they contain. In general you will need 1 bomb per room you are treating; however in some cases, 1 bomb in a hallway adjacent to open doors can treat multiple rooms. Read the label carefully to determine the size of the area the product treats. Ask your veterinarian for his or her advice on which products they recommend. Check with friends and family for their opinions on the effectiveness of a flea bomb they might have used, or check online for feedback and reviews. Ask sales associates at your local home improvement or hardware store for any information they may have concerning flea bombs, but always back up what you're told by a retailer with your own quality research. Most flea bombs operate in similar ways. Ensure that you have read the directions carefully and fully prior to setting off the flea bomb in your home. The chemicals in the flea bomb are poisons which can easily cause illness to people and pets. Check the label on your flea bomb to ensure that your family is safe and can stay out of the house for the label's recommended time period. Open all doors to infested rooms so the chemicals from the flea bomb can kill the fleas. Open cabinet doors and drawers to kill fleas inside furniture. Remove such items from open cabinet doors or drawers to keep them away from the spray. Storing items away from the chemicals is much easier than cleaning them when the flea bomb is finished. The chemicals from the flea bomb can soil furniture, tables and countertops or damage electronic equipment. Cover these items with sheets or plastic tarps to prevent damage. Old sheets can be found easily at your local thrift store. Plastic painting tarps are available from hardware and auto stores. Chemicals in a flea bomb are dangerous to fish. If you can't move your fish tank to another location, cover it up well and seal it tightly with plastic wrap. The chemicals and propellants in a flea bomb can be flammable. Turn off the heater or air conditioner...
