Not to worry, though! After finishing this article, you will understand what I, as a yard and garden owner, depend on to kill fleas in the yard and keep these pests from infesting it in the first place! Keep reading!

What should you know about fleas?

Let’s begin with the basics. What is a flea, and how do they function? Fleas are extremely small pests, rather parasites, extremely tiny in size, either dark brown or black, and move about from one host to the other by jumping. Thankfully, these bugs can not fly.

Now, fleas are particularly unhealthy insects to have anywhere around you, let alone just your yard, because they carry severe diseases and other parasites. These diseases can affect both your pets and you. Another annoying fact about these bugs is that you have to guard against them throughout the year.

What is the life cycle of a flea?

The life cycle of a flea is divided into four main stages. These stages begin with the egg stage, which hatches into larvae. These larvae develop into pupae and, ultimately, completely adult fleas.

It is worth remembering that an adult flea can deliver about fifty eggs daily. Therefore, it is essential to take action as soon as you discover a flea because where there is one, there is certainly bound to be more.

Where do fleas live outside your homes?

Fleas thrive in environments shielded from light and have a high humidity level. This explains why your yard makes for a perfectly good nesting spot for these bugs. You will often find that fleas are lurking about in your unkempt lawn or rows of shrubs and bushes in your yard.

They depend upon the organic matter they can eat on or preferably a host whose blood they can suck on for their sustenance. There is a good chance that stray animals or unhygienic animals that wander into your yard will deposit fleas into your yard and onto your pet.

How long can a flea infestation survive in your yard?

Even when a flea cannot find a host animal to survive on, these pests can live for over three months. However, in the absence of a host animal, fleas cannot reproduce.

Fleas often make their home in unkempt yards.

Therefore, there is a high chance that these bugs will die out by themselves if you keep unhygienic animals off your property and ensure that your pet stays free of these parasites.

If fleas do find a host animal, then within three to four days, you will have over fifty new fleas burgeoning on the animal and, consequently, in the vegetation in your yard.

This is why I would like to stress again that if you neglect the signs of flea infestation in its early stages, it becomes progressively more difficult to eliminate them!

In the next section, I have highlighted ways of detecting the signs of a flea infestation that you must be attentive toward.

How to detect flea infestations in your yard?

The obvious method is to try and spot these insects moving about in your plants. However, given that these bugs are very small in size and hide extremely well, that might prove to be difficult unless you have a large infestation already.

Therefore, a reliable method is to draw the fleas out by wearing white socks or stockings and standing in your yard. The chances are that fleas will be attracted to the light color and jump onto it. Once they do, it becomes easier for you to spot them on the contrasting white fabric!

If you have a pet, noticing a flea infestation in their fur might answer your question about having fleas in the yard.

Excessive itchiness, clusters of red spots, or insect bites on your pet’s skin are two of the most common symptoms of flea infestation. In some cases, your pet can contract tapeworms from these parasites along with several other diseases.
