Are you tired of bad smells and cockroaches that appear down the bathroom drain? This simple trick, which only requires a plastic bottle, is a practical, economical and effective solution to these problems.
With just a few steps, you can avoid discomfort and keep your bathroom more hygienic and enjoyable. Find out how to apply this method at home and enjoy its benefits.

How to apply the bottle trick step by step
This trick is very easy to perform and only requires a small plastic bottle, scissors, and some patience. Here’s how to do it from start to finish:
- Get a small plastic bottle: You can use a standard-sized water or soda bottle. Make sure it’s small enough to fit in the bathroom drain. The size of the bottle will depend on the size of the drain.
- Cut the base of the bottle: Use scissors or a box cutter to cut the base of the bottle, removing the bottom so that it is open. This part will be the one that will allow the water to pass through without problem, while keeping cockroaches and odors out.
- Make small holes around the bottle: Drill small holes along the entire length of the bottle, including the cap. These holes should be small enough to allow water to pass through, but not so large that they let insects through. You can use an awl, a thin screwdriver, or any similar tool to make the holes.
- Place the bottle in the drain: Insert the bottle with the lid down into the bathroom drain. The cut part should be facing up, allowing the water to flow normally. The lid prevents insects and odors from rising through the drain.
- Adjust and check: Make sure the bottle is properly seated and fits into the drain for it to work effectively. If necessary, you can drill more holes or adjust the position.
Why does this trick work?
The bottle acts as a physical barrier that prevents cockroaches from climbing and blocks unpleasant odors from the pipes. Being permeable to water thanks to the holes, it allows unobstructed flow, but insects and bad odor are trapped.
This method is a simple and inexpensive solution that you can do with materials you already have at home, and it offers easy maintenance to keep the drain clean and free of pests. Put it into practice and you will see the results!
