What Are the Signs of Cockroach Infestation?Cockroaches may bring to mind dirty, disgusting city dwellings, but in reality, they can live anywhere that offers food, water, and a warm shelter. They aren’t just nuisance pests, either; they are a real public health problem and can contaminate food and eating utensils with bacteria like Salmonella and E. coli. There are things to look for that show signs of cockroach infestation.

Being nocturnal insects, you’re not likely to see these pests during the day, unless you have a serious cockroach problem. Cockroaches can hide in the narrowest of spaces, flattening their bodies to fit under floor drains, inside motors and major appliances, beneath rubber mats, behind wallpaper, and even within wall cracks. There are, however, several other signs that you have a cockroach infestation.

Five Signs of Cockroach Infestation

Fecal Droppings

Cockroaches leave behind fecal droppings, ranging from small black droppings that are similar in size to ground coffee or black paper for smaller roaches, to larger cylindrical leavings for larger bugs. The quantity of feces is a good indicator of the level of cockroach infestation; the longer the insects have been around or the more cockroaches there are, the more feces they leave. The good news is that these leavings give you primary areas to target when you try to kill them; these are likely high traffic areas for the pests.

Unpleasant Smells

On its own, a single cockroach won’t emit much of an odor. Some species of cockroaches emit a strong oily or musty smell, which becomes particularly noticeable with a large cockroach infestation.

Dead Cockroaches

Check under sinks and the stove, in cabinets, and around the refrigerator for cockroach corpses. These are common areas where cockroaches like to hide, so it’s not uncommon to find dead ones in those areas.

If you’ve left out cockroach traps, you may also find dead (or even living) bugs in stuck in these traps to further prove your suspicions of a cockroach infestation.

Egg Casings

Cockroaches produce brownish oval-shaped egg casings, called oothecae. Casings for three of the four most common roaches in the US can hold between 10 and 20 eggs, while the German cockroach casings can hold as many as 50 eggs inside.

While some roach species carry their eggs until they hatch, others leave them hidden in a safe place, typically the same places the roaches themselves like to hide. Check for egg casings behind furniture and even between books on the bookshelf if you suspect you have cockroaches.

Live Cockroaches

Cockroaches are nocturnal, but this doesn’t mean you won’t see them at all. They often come out to scavenge for food and water at night, when you’re probably asleep. You may see them during the day, but this typically happens when the cockroach infestation is so large that some of the roaches are pushed out of their nests.
