    Do Fleas Live In Your Yard?

    Fleas are pesky and stubborn parasites that can often be found on the back, neck, and underside of felines and canines. In severe infestations, fleas of different life stages from egg to adult can be easily found settling inside your pet’s bedding, your living room carpet, and even inside your bedroom.

    But before they are able to find their way inside your house, have you ever wondered where fleas could be coming from?

    Basically, fleas love moist, humid, and shady conditions. And such an environment is often tantamount to your yard especially if you have woodpiles and tall grasses in one corner or the other. Other possible places where fleas could be coming from are dog houses, public parks, and even hotels.

    This is especially true in generally humid cities and states, but it is relative. A city like Nashville, TN, which is prone to higher humidity will likely have more fleas. Whereas somewhere like Arlington, VA, which is more of a “four seasons” city and state will have a season of “peak activity” in the warmer months – though fleas can be present year-round.

    Will Fleas Infest Your Yard?

    Yes, unfortunately!

    Whether you like it or not, flea populations thrive in environments such as your yard. However, the chances of harboring fleas inside your yard or garden can be significantly reduced by trimming the grass, branches, and foliage.

    This helps eliminate or at least reduce the shady conditions of your yard which is ideal for the survival of flea larvae.

    Basically, chemical treatment can help curb your problem on flea infestations but only for a certain period of time. Furthermore, most pesticides are formulated only to kill adult fleas, leaving behind eggs and larvae to flourish in the future.

    For this reason, it is critical to employ other methods of control to make your yard flea free.

    Are There Any Home Remedies In Treating Your Yard From Fleas?

    Chemical treatment or the use of pesticide is no doubt the most efficient solution in curbing the flea infestation in your yard.

    However, there are also other effective alternatives that are easily found inside your home especially when you feel too tired to visit the nearest hardware store.

    Here are some effective home remedies in treating your yard from fleas:

    Dish soap trap

    This trap is made by mixing the dish soap that you usually use and warm water. Secure the mixture in a bowl.

    The solution yields a fluid with high viscosity that can effectively trap fleas as well as other types of insect pests that land on it. Place multiple dish soap traps in pre-determined areas of your yard with high flea activity.

    Fine salt

    Salt is another home remedy that you can count on in your fight against fleas invading your yard. This solution works on fleas of all stages.

    Use finely ground salt and sprinkle it throughout your yard especially on shady and moist areas. The salt is an ionic compound and is capable of attracting moisture from its direct environment. Against fleas, the salt works as a dehydration agent desiccating the bodies of fleas, larvae, and even its eggs.

    Diatomaceous earth

    Apart from salt, you can also use diatomaceous earth to dehydrate fleas. DE is a special type of sedimentary rock ground into fine granules. It is basically made of fossilized remains of diatoms. These are aquatic microorganisms whose skeletons are practically made of silica.

    Microscopically, granules of diatomaceous earth are razor sharp shells that can easily cut through the exoskeleton of fleas and suck out moisture. However, make sure that you apply DE over dry surface. This special type of sand loses its effectiveness in killing fleas when wet.

    What Is The Best Flea Treatment For Your Yard?

    Chemical treatment or the use of insecticidal spray is definitely  the best way to combat flea infestation on your yard. However, bear in mind that not all flea control insecticides work the same way.

    The most commonly used flea sprays are those equipped with pyrethrin. This special type of pesticide chemical is commonly used on households due to its extremely low toxicity on humans while being highly effective in killing adult fleas.

    IGR sprays are another type of chemical treatment used against fleas in the yard. Insect Growth Regulator pesticides work on the flea larvae and prevent them from reaching full maturity. To get the best results out of your chemical treatment, it is strongly advised to use both pyrethrin and IGR sprays hand in hand in totally eradicating fleas from your yard.

    Flea Warning

    If you do think you have fleas in your yard, we highly recommend first consulting with an exterminator before using sprays or any other method of flea control. Improper use can pose a serious threat to human health and make your flea problem worse.
