How to Get Rid of Cockroaches Coming From Neighbour Flats in Hyderabad (2025 Practical Guide)

Let’s be honest. You keep your home clean… You dry your kitchen at night… You close your drains… You do pest control regularly… But cockroaches STILL enter. Why?

Because they’re coming from neighbour flats through:

• Drainage lines
• Shared bathroom pipelines
• Kitchen sink lines
• Balcony gaps
• Electrical conduits
• Vent shafts

This is one of the MOST COMMON cockroach problems in Hyderabad apartments.

The good news? You can stop neighbour cockroaches permanently — if you block the right entry points and follow the exact method below. Let’s break it down in clean, clear Neil Patel style.

Why Cockroaches Come From Neighbour Flats

Here’s the real truth: Even if **YOU** maintain your home perfectly, cockroaches will enter if:

• Your neighbour has an infestation
• They don’t do pest control
• Their kitchen is always wet
• Their bathroom drain is open
• They keep trash overnight

Cockroaches don’t respect borders. They use the building’s pipeline system like a highway.

Main Entry Points Cockroaches Use Between Flats

These are the exact routes roaches use to travel from neighbour flats:

• Common bathroom drain line
• Kitchen sink drainage pipe
• Wall-floor joint pipeline
• Utility drain
• Balcony water outlet
• Electrical cable shaft
• Exhaust fan gaps
• Cracks between shared walls

If ANY of these are open → cockroaches enter.

How to Stop Cockroaches Coming From Neighbour Flats (Complete Solution)

These methods are used by Hyderabad’s top pest control experts.

1. Close Bathroom Drains Completely at Night (The most important step)

Every flat shares the same drainage pipeline. If the neighbour’s drain is open → cockroaches enter YOUR bathroom.

Fix: Use steel drain covers, Use rubber drain caps, Ensure flap closes tightly, Don’t leave drains open after showering. This alone reduces 50% of cockroach entry.

2. Seal the Gap Around Kitchen Sink Outlet

Behind every kitchen sink, there is a big round hole in the wall where the drain pipe enters. Roaches enter through this gap.

Fix it using: White cement, Silicone sealant, PVC collar ring. One-time fix → permanent result.

3. Seal Gaps Under Bathroom Tiles

Shared walls or old tiles create space for cockroaches to crawl through. If tiles sound hollow or have cracks: Fill with grout, Use tile adhesive, Use cement filler. Quick fix, high impact.

4. Keep Bathroom Completely Dry at Night

Neighbour’s moisture becomes YOUR cockroach problem. Dry bathroom: Floor, Corners, Under the sink, Around commode, Behind buckets. Roaches come searching for night moisture.

5. Install Net Mesh on Exhaust Fan Openings

6. Fix Gaps Around Pipes (Water, Jet Spray, Tap Lines)

Plumbers leave gaps around: Jet spray pipes, Tap pipelines, Water connections, Geyser lines. Cockroaches crawl through these 1-inch openings. Seal with: White cement, Silicone, M-Seal.
