A huge range of flea treatments is available these days, but sometimes infestations spread beyond the help of topical treatments.

You can treat your pet for fleas religiously, but dogs with flea sensitivity will not respond to treatments unless they also include environmental controls. If your companion spends a good deal of time outdoors, it’s important to treat these areas to manage for fleas and other pests.
 
When making a list of steps you should take in addressing Fido’s outdoor flea problem, you should first account for which areas need treating. These should include any spot where your pet sleeps, such as his doghouse, kennel, carport, and even under the deck. Other areas to be treated include moist, shady spot where fleas breed; gardens; shrubs; and mulched areas. To rid these areas of fleas, many pet owners use pyrethroid sprays famous for killing fleas and ticks fast. These can be applied through a sprayer attached to a hose, allowing rapid treatment of large areas, or can be diluted and applied with a watering can on smaller spaces. Make sure to remove any pet or children’s toys before beginning this process.
 
Although pyrethroids are chemical imitations of pyrethrins—naturally occurring compounds that incapacitate insect nervous systems—not all pet owners are comfortable spraying them in their yards. Alternatives include desiccants, which are naturally occurring substances that pull water from fleas, causing them to dry up. Diatomaceous earth, silica gel, and sodium borate are all desiccants that can be applied in your yard to control fleas and other pests. Another natural solution to outdoor flea infestations are beneficial nematodes. Microscopic roundworms available at many garden centers, nematodes kill pests and other insects by entering the body and releasing a bacteria that kills fleas quickly. While they can be highly effective in some situations, nematodes have a limited area and season of usefulness, as they die in temperatures above 95 Fahrenheit and below 45, and are sensitive to light and drought. Cedar wood chips are another natural alternative to fighting fleas, as fleas are repelled by their scent. Sprinkle chips in shady areas, such as under the porch, and in dog bedding and outdoor furniture.
 
To keep a serious flea infestation at bay, repeat your outdoor treatment every two to three weeks, for at least six weeks. Once your pest problem is under control, you can drop to regular maintenance treatments every four to six weeks throughout the flea season. You should continue using your regular flea treatments on all of your pets throughout the process, and be sure to consult your veterinarian before treating your yard to make sure your pest prevention program won’t harm you or your canine companion.
