Cockroach Infestation

A cockroach infestation is more than an unpleasant surprise — it can impact hygiene, trigger allergies, and spread rapidly if nesting areas are not treated properly. Cockroaches hide in tight spaces, multiply fast, and often remain unseen until the problem becomes serious. The key to long-term results is inspection + targeted treatment + prevention.

The video above shows real cockroach activity and professional treatment methods. Many infestations start in kitchens and laundries, then spread through wall cavities, roof voids, and shared plumbing lines.

What Is a Cockroach Infestation?

A cockroach infestation happens when cockroaches establish one or more nesting areas inside a property and reproduce faster than the problem can be controlled. Roaches prefer warm, dark, and moist places close to food and water. That’s why infestations commonly appear in kitchens, bathrooms, and roof voids.

Important: seeing one cockroach during the day can indicate a bigger problem. Roaches are typically nocturnal, so daytime activity often suggests overcrowding in hiding spots.

Why Cockroach Infestations Are Hard to Eliminate

Cockroaches are resilient, fast, and excellent at hiding. Many DIY treatments fail because they only target visible roaches rather than the nesting zones. If eggs and hidden harbourage areas are not treated, the infestation returns again and again.

How fast do cockroaches multiply?

A single female can produce many egg cases over her lifetime, which means the population can explode quickly. This is why early inspection and treatment saves time and cost.

Signs of a Cockroach Infestation

• Roaches seen at night (or worse — during the day)
• Small droppings that look like black pepper or coffee grounds
• Egg cases near cupboards, appliances, or cracks
• Musty or oily smell behind the fridge or oven
• Shed skins in drawers, cupboards, or pantry corners

Can Cockroach Infestations Cause Health Problems?

Yes. Cockroaches can carry bacteria from drains and waste areas and transfer it onto food preparation surfaces. Their droppings, saliva, and shed skins can also trigger allergies and asthma — especially in children and sensitive individuals.

Are cockroaches dangerous in kitchens?

Roaches often travel between drains, bins, and food areas. This movement can contaminate benches, cupboards, and utensils. If you’re seeing roaches near food preparation zones, it’s best to arrange professional inspection.

Where Do Cockroaches Hide During an Infestation?

During inspections, cockroaches are commonly found in:

• Behind refrigerators, ovens, and dishwashers
• Under sinks and around pipe penetrations
• Inside cupboards, drawers, and pantry corners
• Bathrooms, laundries, and floor drains
• Garages, storage areas, and cardboard boxes
• Roof voids, wall cavities, and weep holes

Best Way to Treat a Cockroach Infestation

The best results come from a combination of: inspection (to find nests), targeted treatment (to reach harbourage areas), and prevention advice (to reduce future activity). Spraying alone often gives short-term relief but misses hidden breeding zones.

Why inspection matters more than “just spraying”

Inspection allows technicians to identify moisture sources, entry points, and nesting locations. Without it, treatments often miss the areas where cockroaches actually live — and the infestation returns.
