When it comes to household pests, few invaders are as relentless and irritating as the tiny but mighty flea. These minuscule menaces, measuring just a few millimeters in size, can turn your peaceful abode into a battleground for both humans and pets.

But what does a flea infestation look like, and how can you spot the telltale signs before they launch a full-scale assault on your home?

Learn more about the danger signs you need to watch out for below.


Itchiness is one of the major flea infestation symptoms.

Flea bites are typically small, red, itchy welts on the skin. They often appear in clusters or a linear pattern, and they can be particularly itchy. Common bite locations include ankles, lower legs, and around the waist.

Some people and pets may be allergic to flea saliva, resulting in more severe itching, hives, and extensive skin inflammation.

Weird Pet Behavior

When your pets are affected by fleas, you might notice unusual or weird behaviors that are indicative of the infestation.

One of the most common signs is when your pets, such as dogs and cats, start scratching, biting, or licking themselves excessively. They may focus on specific areas of their body, often their hindquarters, the base of the tail, or around the neck. This behavior is a response to the discomfort caused by the bites.

Pets may avoid specific areas of your home where fleas are more concentrated. If your pet avoids their bedding or a particular room, it could be a sign of a flea issue.

If you see any of these behaviors, you’ll want to bring in pest control services for flea infestation treatment ASAP. You also might need to take your pets to the veterinarian. 

Reddish-Brown Specks

The presence of reddish-brown specks, often referred to as “flea dirt,” is one of the common signs of a flea infestation in a home. 

Flea dirt is a result of fleas feeding on blood, and it consists of digested blood, making it a source of nourishment for flea larvae. If you notice these reddish-brown specks in your home or on your pets, it’s a strong indication of a flea problem.

Flea Eggs

Flea eggs are another common indicator of a flea infestation in a home. These eggs are tiny, oval-shaped, and typically white or off-white.

Flea eggs can often be found on your pets, especially in areas where fleas are active. They are small and usually attached to the fur, close to the skin.

These eggs can fall off your pets and onto carpets or rugs where they may become embedded in the fibers. They are often found in areas where your pets spend a lot of time.
