How to Kill Fleas in the Yard


Flea control is a difficult task. The normal life cycle of the flea is approximately four weeks. During that time the flea hatches from an egg, goes through a larval stage and then begins to reproduce. Begin eradicating fleas as early as possible, treating the soil as early as March or April. If the infestation is too great, you may want to call in a Pest Control Operator (PCO). Products on the market can be applied to the yard with relative safety.

Step 1

Understand that fleas can be carried into your yard by any animal, not just your pets. The night visiting possum or raccoons can spread fleas into the yard. Other daylight animals such as squirrels or rodents can harbor enough fleas to create a small infestation. If you have dogs or cats, consider erecting small diameter fencing to keep some of these animals from your yard.

Step 2

Eliminate areas in the yard with heavy moisture content and plenty of shade. Dogs may want to lay there during warm summer days, propagating the flea population. Erect small fence barriers for these areas.

Step 3

Consult your local veterinarian for flea products that can be applied directly to your animals. Various climates may require different chemicals for your pets and animals.

Step 4

Use an approved spreader to apply flea control granules to your yard. Consult the manufacturer for the correct dosage and application methods. You may need to repeat applications. Concentrate on areas of the yard where pets tend to congregate as these areas will have the heaviest concentrations of the fleas, eggs and larvae.

Step 5

Contact your local agricultural extension service, which will have extensive literature on chemicals available for your area and climate. With more than 2,000 flea species worldwide, not all species will be eliminated by common pesticides.

Tips and Warnings

  • Use extreme caution when applying any flea chemical to the yard. Children and pets should not be allowed in the area until the chemical has thoroughly dried or been worked into the soil. Protect plants and fish tanks as the dosage may harm them as well.
