Bristle Worm Trap


NEW V3 version based on customers and R2R user feedback


To battle a single bristle worm or a bigger bristle worm infestation, you will need our trap in your aquarium. With our trap, there's nowhere left for a bristle worm to hide.

Simply place our bristleworm trap on top of your saltwater aquarium substrate or sand and weigh it down with rocks, or wedge it between a sturdy structure. It is made from plastic so it will float away in the current! Put a small amount of meaty food inside it to draw the attention of the hungry guys infesting your saltwater tank. This draws them away from the decaying matter, dead fish, and other detritus they normally feast on. Then, leave it in your tank overnight or for a few days to catch as many as possible.

How do our bristle worm traps work?

The bristleworms which are living in your aquarium will never turn down a feed when it's offered to them. Simply put a meaty treat into the center of our bristle worm trap and the bristle worms will swim directly into it through the evenly spaced holes on the outside.

You can attract bristle worms into the trap with a variety of different types of food like raw shrimp meat or frozen fish food. Also, algae wavers work very well! They won't be able to resist.

Our bristle worm trap features a plexiglass window on the top so you can see just what it's caught.

That means no more stuffing bait inside a small piece of live rock rubble and leaving it overnight to catch these critters. No more sitting in a darkened room with a flashlight waiting patiently to wait for a bristleworm to crawl out of the sand which you then pounce at with your tweezers.

Please be assured that each bristleworm trap is made with 100% reef safe PETG high-quality filament. PETG is safe for food containers and tools used for food consumption. Our traps are available in black, white, or orange colors.

    Worms keep getting out.

    The trap does work. It seem to attract worms to go into it. I tried this and if you submerge in water the trap and then close the lid it actually sinks and doesn't need anything to hold it down. The worms seem to be able to get in to it. When I go to bed I see a few of them. Multiple Long bristleworms. And hundreds of other worms crawling all over the tank. I wake up in the morning and there's either nothing in there or 1 or 2 baby bristle worms. They seem to finish the food and just get out of it. Tried it for over a week and now have given up on it. It was like I was feeding them a whole cube of mysis every night and helping them multiply. I'll just cut down on excess feeding so the population goes down naturally.
