Simple Ways to Stop Cockroaches From Entering Through Your Shower Drain
1. Why Roaches Enter the Bathroom
Warm, humid bathrooms attract pests, especially when they
“sneak in through the shower drain.”
Even with regular cleaning, plumbing can remain a common entry point.
2. How the Balloon Method Works
Cockroaches travel through “pipes and tiny openings,”
which is why narrowing the drain helps.
Cut both ends off a balloon to form a ring,
then slide it onto the drain cover so it creates “a tight seal” when replaced.
3. Keeping the Space Dry
The balloon leaves a smaller opening that blocks most pests while still allowing water through.
Pair this with moisture control—
“wiping surfaces, running ventilation fans, and cleaning around drains”—
to make the bathroom less inviting.
4. Strengthening Your Barrier
Seal cracks or gaps around pipes to stop hidden entry points.
Combined with routine upkeep, these steps
“create a stronger barrier against pests” and keep your bathroom more comfortable.
