Cockroaches are one of the most unwelcome guests you can have in your home. They spread diseases, trigger allergies, and let’s be honest, they are just downright unsightly! Identifying a cockroach infestation early on can prevent a small problem from escalating. We share some common signs to look out for if you suspect you have a cockroach infestation at home.
Signs of Cockroaches
Telltale signs that cockroaches have invaded your home can manifest as both physical signs or might trigger other senses:
Droppings
Cockroach droppings resemble small, dark specks or coffee grounds and are often found in corners, along baseboards, and near food sources. If you notice these tiny black dots in various areas of your home, it may indicate a cockroach presence.
Eggs
Cockroaches lay eggs in protected areas such as behind appliances, inside cabinets, or within wall voids. The eggs are typically white or light brown and are enclosed in an egg case. These can be signs of an active infestation.
Unusual Odours
Cockroaches emit a pungent, musty odour that is often compared to the smell of rotting food or sewage. This smell becomes more pronounced as the infestation grows. If your home has an unexplained foul smell that persists despite cleaning efforts, it could be due to cockroaches. The best course of action is to get a professional pest control service to inspect your home.
Stains
Cockroaches can leave behind yellowish or brownish stains on surfaces where they have been present. These stains are usually found near food sources or in areas where the cockroaches rest. They can also leave dark smudges on walls and floors.

Health Symptoms and Allergies
Cockroaches are known to trigger allergies and aggravate respiratory conditions like asthma. Their saliva, faeces, and body parts contain allergens that can become airborne and cause symptoms such as sneezing, coughing, and itchy eyes.
Children and people with pre-existing allergies are particularly susceptible to the allergens left behind by cockroaches. If you or a family member is experiencing unexplained allergic reactions or respiratory issues, it could be linked to a cockroach infestation and professional cockroach control is essential.
Disease Transmission
Cockroaches can carry and transmit several diseases including gastroenteritis, dysentery, and cholera. They pick up pathogens from contaminated surfaces and then transfer them to clean surfaces or food items. Maintaining hygiene in your home is key in preventing the spread of diseases.
Common Areas to Check for a Cockroach Infestation
Cockroaches tend to thrive in dark, damp areas with access to food and water. Here are some common places to check for signs of an infestation:
Kitchen
The kitchen is often a hotspot for cockroach activity due to the presence of food and moisture. Check behind appliances like refrigerators and dishwashers, inside cabinets, and under sink areas.
Bathrooms
Bathrooms provide another favourable environment for cockroaches with their moist conditions. Look around sinks, toilets, and showers for signs of cockroach activity.
Basements and Attics
These areas are often less frequented but can provide ideal hiding spots for cockroaches. Check for droppings or egg cases in these areas.
