Cockroaches are a common household pest found in many areas of Florida. A study from the United States Department of HUD shows that 30.4% of Florida homeowners reported at least one roach infestation per year. Thanks to the state’s warm and humid climate, it provides an ideal breeding ground for these pests. So, it’s significant for homeowners to be aware of cockroach infestation signs to prevent an outbreak beforehand.

Although roach invasions can be challenging to spot, these insects are skilled at hiding and can reproduce quickly. But with an appropriate guide, you can definitely identify their presence in your place. This blog helps you to spot these invaders before the problem gets worse. Let’s discuss the top 7 most common signs of cockroaches in Florida.

Cockroach Droppings

One of the early signs of roaches is fecal matter. Cockroaches produce dark, cylindrical droppings resembling black pepper or coffee grounds. You may find these droppings in areas where cockroaches are likely to be. For example, near food sources, in cabinets, or behind appliances.

The size of the droppings can vary depending on the cockroach size. However, as a general rule, the droppings will be smaller than a grain of rice. You may also notice a musty, unpleasant odor in areas with large numbers of cockroaches. The accumulation of fecal matter causes it. So, you can identify the invaders by spotting these cockroach infestation signs.

Egg Cases

Finding egg cases is one of the apparent cockroach infestation signs. Roaches lay their eggs in protective cases called oothecae. These cases are small, oval-shaped, and brown. You may find them in dark, hidden areas such as behind furniture or wall cracks. The size of the oothecae can vary depending on the cockroach species, such as American roaches’ ootheca is 8 mm long.

If you find an ootheca, it strongly indicates that roaches are present in your home, offices, and other dwellings. For cockroach pest control, it is essential to dispose of it immediately. Otherwise, the eggs inside may hatch, and you will face a new generation of cockroaches.

Unpleasant Pungent Odor

Cockroaches emit a musty, oily odor that can be very unpleasant. This odor is usually more noticeable in areas with established colonies of invaders. For instance, you may detect an odor in a kitchen or bathroom. The aroma is caused by the accumulation of fecal matter and the secretion of pheromones.

If you notice a pungent odor in your home, it is crucial to investigate the source. If you suspect that a cockroach infestation may cause it, you should take steps to identify and eliminate the invasion as soon as possible.

Shed Skins

As cockroaches grow, they shed their skins. You may find these shed skins in areas where cockroaches hide, such as in cupboards, behind appliances, or in wall cracks. The skins are typically light brown or tan and can be difficult to distinguish from other debris.

If you find shed skins in your home, it is important to take action to eliminate cockroach infestation signs. Roaches reproduce quickly, so the presence of shed skins indicates that the population is growing.

Smear Marks

You may not overlook smear marks when it comes to cockroach infestation signs. Cockroaches have oily bodies that can leave smear marks on surfaces where they have crawled. These marks may appear as dark, irregular streaks or smudges. They can be found on walls, floors, and other surfaces.

If you notice smear marks in your home, it is important to investigate further to determine if a cockroach infestation exists. Once you have confirmed that there is an infestation, you should take cockroach exterminator actions as soon as possible.

Damage to the Property

Property damage is one of the critical cockroach infestation signs. And should be taken seriously if noticed in your home. Cockroaches are known to feed on a wide range of organic materials, including paper and fabric. If they invade a home, they may start feeding on these materials. It can cause damage over time. For example, they may chew holes in clothing or books or damage wallpaper or other wall coverings.

So, If you observe any signs of damage to your property, it is significant to take immediate action to alleviate the effect. For this purpose, you can also consult professionals for effective roach pest control services.

Live Cockroaches

The most obvious signs of cockroaches are seeing live invaders in your home. These pests are nocturnal, so you may see them scurrying across the floor or walls at night. If you see one cockroach, it is likely that there are many more hiding nearby.

Cockroaches are attracted to warm, moist environments, so they are most commonly found in kitchens, bathrooms, and basements. They can also hide in cracks and crevices, so it is important to thoroughly inspect these areas if you suspect these cockroach infestation signs.


In short, a cockroach infestation can be a challenging problem for Coral Springs homeowners if not checked out properly. It’s important to be vigilant for indications of their presence in your home.
