How to Identify a Cockroach Infestation

**Hearing bumps in the night? Sniffing out funky smells? Seeing cockroaches dart around?** You might just be dealing with a creepy-crawly takeover! Spot the signs of a cockroach infestation early. Hustle to keep your space safe from these uninvited guests!

Physical sightings of cockroaches

Do you suspect a cockroach infestation? Look for physical sightings of cockroaches. Seeing one during the day is a sign of a severe infestation. They usually hide at night.

Check places near water sources, like kitchens, bathrooms and basements. Also, they’re drawn to food left out in the open.

You may also find cockroach droppings, shed skin or empty egg cases, as well as a musty odor.

If you have identified signs of a cockroach infestation, call a professional cockroach control service right away. Don’t wait – the infestation can get worse!

Evidence of cockroach feces

Cockroach feces are a telltale sign of infestation. They’re simple to spot, and can be seen in many spots in your house. Here’s what to look for:

  • Size – usually less than 2mm long.
  • Shape – capsule-like with ridges.
  • Color – brown or black when fresh, but lightens over time.
  • Location – in places cockroaches like, such as cabinets, drawers, countertops, and behind appliances.

If you see them, take action fast to find and remove the source. Pro Tip: Put on gloves and a mask before handling the droppings, to avoid bacteria and allergens.

Unpleasant odor

A nasty smell may be a sign of a cockroach infestation in your home. The smell is a mix of chemicals from the cockroach’s body and its poo. If you detect a weird, strong scent in your kitchen or moist areas, check for cockroaches. Other signs to look out for include:

  • live/dead cockroaches
  • droppings
  • egg casings

It is important to deal with the problem ASAP to avoid health risks and damage. Pro Tip: Use baits and traps. Keep your home clean to prevent infestations.

Egg casings or shed skin

Exoskeletons and egg casings are telltale signs of a cockroach infestation.

  • Cockroaches shed their exoskeleton as they grow, leaving them around the home. These are brown and translucent and are often seen near food sources, behind furniture, on countertops and cupboards.
  • Egg cases are small, brown and oval-shaped. Each one can contain up to 50 eggs and can be found in cracks and crevices. Insecticides don’t affect them, so it’s best to remove them by hand.

If you spot either of these signs, it’s likely you have an infestation and must take action right away.

Grease marks on surfaces

Grease marks? They’re a telltale sign of cockroach infestations! These critters leave oily residue as they roam and feed. Here’s how to spot them and treat an infestation:

  • Look for small, brown droppings that look like ground coffee or pepper flakes. Especially in areas where food is stored or prepared.
  • Check for egg cases that are small, brown, and cylindrical.
  • Search for live or dead cockroaches in warm, damp, and dark places. Like basements, bathrooms, and kitchens.

To treat the infestation, reduce food sources, seal up cracks and crevices, and use baits and insecticides made for cockroaches.


Finally, spot the signs of a cockroach infestation with ease. Here’s what you should look for:

  • Live or dead cockroaches in parts of your home like the kitchen, bathroom, and basement.
  • Bad smell in places cockroaches may live.
  • Droppings that appear like black pepper or coffee grounds in places where cockroaches are active.
  • Skin or egg casings in hard-to-reach areas.

If you think there’s an infestation, immediately clean, seal any entry points, and consider professional pest control services. Quick action can prevent the problem from getting worse!

Pro Tip: These critters are nocturnal, so use a flashlight to inspect gaps, cracks, and crevices.
