Cockroach Killer

I despise cockroaches! Therefore, I created this cockroach trap. It features a threaded end for attaching mineral water bottles (compatible with standard 28mm threaded bottles); the other end is equipped with a one-way door that allows cockroaches to enter but prevents them from exiting. To use it, place some food crumbs, such as sugar, inside and outside the bottle to entice the cockroaches. Afterwards, all you need to do is replace the bottle, making it simple and convenient!

I hate cockroaches! So I made this cockroach trap. One side of it is threaded, used for installing mineral water bottles (compatible with regular 28mm threaded bottles); On the other side is a one-way door, where cockroaches can only enter but not exit. When you use it, you need to place some food debris inside and outside the bottle to attract cockroaches. Then dispose of the cockroaches, you just need to replace the bottle, it's simple and convenient!
