Roaches Next Door? They Share Your Walls

Why apartments are different
In a house, the pest problem is usually contained within your own property. In an apartment building, walls, floors, plumbing and electrical runs connect every unit. Roaches use these routes to move around, so what's happening next door can affect you.
Signs that it's coming from outside your unit
- Roaches appear around pipes, under sinks and in bathrooms even though you keep the unit clean.
- You see more roaches at night, especially near shared walls.
- Neighbours report roaches too.
- Treatment in your unit helps for a short time, then they return.
What you can do as a resident
- Keep food in sealed containers, and take rubbish out daily.
- Fix leaks and dry sinks overnight.
- Clean behind and under appliances.
- Seal gaps around pipes and cabinets, if you're permitted to.
- Report the problem to your landlord or property manager in writing, with photos and dates.
- Let them know if neighbours are affected too.
Why foggers and sprays may not be enough
Over-the-counter fogs and sprays can kill roaches you can see, but they can also push roaches into other units or deeper into the walls. A coordinated approach that treats affected units and shared areas is usually more effective.
For landlords and property managers
Treat reports quickly, check neighbouring units and common areas, and consider regular preventative visits. It's usually cheaper and less disruptive than reacting each time a tenant complains.
When you should call a pest control company
- Roaches keep returning after you treat your unit.
- Neighbours have roaches too.
- You manage an apartment building or rental units.
- You want a coordinated plan for several units.
What happens at an inspection
A technician checks inside and outside the property, looks for signs of activity, works out where pests are getting in and what is attracting them, and explains what was found. You then get a clear recommendation. Protek Pest Services offers a free, no-obligation inspection across St. Kitts & Nevis.
