Have you noticed more roaches in your kitchen lately? As humidity rises, roach activity increases, especially from big roaches seeking cool, damp hiding places. The space under your sink offers everything they need, making it a familiar nesting spot.
Keep reading to discover what draws them to this space and how to prevent an infestation.
Why Big Roaches Love Nesting Under Sinks
During warm, humid months, kitchen and bathroom sinks become prime real estate for pests. These locations often go unchecked, offering the perfect combination for nesting. The following conditions make under-sink areas especially appealing to big roaches:
- Darkness and shelter: Under-sink cabinets provide ideal cover during the day.
- Moisture: Leaks, condensation, or damp materials give roaches the water they need to survive.
- Access to food: Crumbs, trash, or pet food stored nearby can support a roach population.
- Warm environment: Pipes and enclosed spaces stabilize temperatures, even at night.
Because under-sink areas provide all these essentials, big roaches are likelier to nest there than in open or dry spaces around the home.
Signs Big Roaches Are Nesting Under Your Sink
It’s easy to miss the early signs of a roach infestation. Even if you don’t see them during the day, their presence often leaves behind clear evidence. The most common indicators of big roaches hiding under your sink include:
- Droppings: Small, dark specks similar to pepper or coffee grounds
- Musty odor: A strong smell that doesn’t go away, often linked to roach pheromones
- Egg casings: Brown, oval-shaped shells found in cabinet corners or along edges
- Smear marks: Greasy streaks left where roaches crawl, especially along walls or pipework
- Live sightings: Roaches scurrying away when you open the cabinet or turn on the lights
If you spot these signs, take prompt action to prevent the infestation from spreading.
Step-by-Step Guide to Stop Roaches from Nesting Under Sinks
Fortunately, there are effective ways to take control of the space beneath your sink. The following steps help remove what attracts big roaches and prevent future nesting:
- Empty and clean the cabinet thoroughly with soapy water.
- Repair leaks and remove any standing water to reduce moisture buildup.
- Seal gaps and cracks around pipes and corners.
- Store all items in sealed plastic bins, not cardboard.
- Place sticky traps or gel bait to monitor activity.
- Check back weekly to keep conditions dry and secure.
Together, these efforts help reduce roach attraction and prevent nesting in the future.
How to Keep Under-Sink Areas Roach-free Long-term
Prevention doesn’t stop after treatment. It’s important to create habits that discourage nesting over time to keep big roaches from coming back. The following tips help maintain a sink area that stays clean, dry, and pest-resistant:
- Wipe spills immediately: Even small drips or splashes can attract roaches if left unattended.
- Inspect plumbing regularly: Look for new leaks or condensation around pipes.
- Take out the trash daily: Roaches often feed on food residue or wrappers stored nearby.
- Avoid storing food below the sink: Keep pet food or snacks in higher, sealed locations.
- Declutter often: Don’t let unused items or packaging pile beneath the sink.
Conclusively, maintaining these habits reduces the chances of big roaches returning and keeps your kitchen or bathroom pest-free year-round.
When to Call a Professional
DIY methods can go a long way, but are not consistent enough. The following signs can help you decide when to bring expert help for big roaches:
- Persistent sightings: Roaches keep appearing despite your efforts.
- Daytime activity: Roaches seen during the day often indicate a large infestation.
- Wider spread: Bugs show up in other areas, not just under the sink.
- Ineffective DIY: Traps and sprays are no longer making a difference.
- Health concerns: Increased allergy symptoms or contamination risks.
Professional help ensures faster and more thorough results if these signs are present.

Don’t let the humid season turn your sink cabinet into a roach retreat. Therefore, you can keep those pests out of sight and at home by staying alert to early signs and following simple prevention steps; consistency matters, especially when moisture and shelter are easy to find.
