What Are the Top 5 Signs of a Cockroach Infestation?


Are you concerned about a possible cockroach infestation in your home? If so, it’s important to know the signs to look for. San Antonio pest control services often advise homeowners to look for key indicators that tell if they have roaches. This blog post will explore the top 5 signs of a cockroach infestation so that you can take the necessary steps to get rid of the pests.

1) Unusual droppings

Droppings are one of the telltale signs that you may have a cockroach infestation. Droppings are dark brown or black and can vary in size depending on the species of cockroach. Keep an eye out for these droppings in hidden or dark corners of your home, such as under appliances and behind cabinets.

2) Smear marks

Smear marks are one of the most common signs of a cockroach infestation. They are brownish or black streaks left on surfaces after a cockroach has crawled across them. Smear marks indicate an active infestation and should be taken seriously.

3) Egg casings

Cockroach egg casings, also known as oothecae, are one of the most common signs of a roach infestation. The casings are reddish-brown in color and about a quarter inch in length. They usually contain several eggs, which are hatched shortly after being laid. Keep an eye out for these, as they indicate the presence of roaches in your home.

4) Shed exoskeletons

Cockroaches shed their exoskeletons as they grow, so seeing the remnants of these shells is a major sign of an infestation. Be sure to look out for any shells lying around in places like under furniture, behind appliances, and in other crevices.

5) Live roaches

Have you seen live roaches in your home? If so, it is likely that your home is infested. Live roaches are one of the most obvious and easily recognizable signs of a cockroach infestation and should not be ignored. Be sure to take immediate action to get rid of them and prevent the further spread of the problem.


In conclusion, cockroaches can be difficult to spot, but they leave behind a few telltale signs that you can look out for. Roaches produce a distinct odor, leave droppings and smear marks on surfaces, may leave egg casings around your home, and even eat through packaging. If you notice any of these signs, contact an exterminator as soon as possible to avoid further infestation.
