1. Dropping

Cockroach droppings are a first and a sure way of telling that the roaches are in the house. When they come out in the night to feed, they will eat anything left in the open and uncovered.

  • They also drop their feces, all over countertops, floors, shelves, and pantry among other areas.

3. Smear marks

Cockroaches have a tendency to leave dark smear trails on the walls as they crawl along.

These marks are visible where the area is humid and moist. They are also the marks that roaches make to and fro as they get to the source of their food.

4. Shredded skin

Roaches molt their skin 8-13 times in their life cycle as they transition from one life stage into another.

  • Look out for these skins as a sign of an infestation of roaches into your home.
  • The shredded skin varies in size and shape as they are molted at different stages of a cockroach’s life.

If you see them in your house, it’s a red alert to take action against the roaches in your home.

5. Strong odor

If your house is having a strong odor, chances are that you have a cockroach infestation. This stench increases as the number of roaches in your house increases. The stench could be as a result of the following;

  • Cockroach dropping
  • Dropping pheromone
  • Dead roaches

The odor from the dropping pheromone is even more likely to attract more roaches into the house if you do not take immediate action.

The German cockroaches who like staying indoors are the number one stench producers.

6. Egg capsules

Cockroaches lay eggs in a capsule that is also called oothecae. One ootheca can contain up to 30 eggs.

  • Though different species have different oothecae, the most common in our houses is the German cockroaches that have 18 segments while American roaches don’t have a defined segment.
  • Some roaches carry the oothecae until before it hatches while others will drop it soon after they land into a new environment.

These oothecae are brown in color and translucent in nature and are normally left behind after the eggs hatch into nymphs.

  • These capsules can be seen in hidden places like under the furniture, in cabinets, and in other hidden dark places – you can use cockroach Bomb.

When you spot the capsules, it’s not time to sit down and relax because cockroaches have already settled in your room.

Cockroaches will feed on anything that they find in the surroundings including, food, fabrics, plastic, and furniture among others.
