Frequently Asked Questions

Q: How does the 3-hole glass planarian trap work in an aquarium?

A: The trap uses bait (such as fish food or a small piece of protein) placed inside the glass tube. Pests like planarians, leeches, and snails are attracted to the bait and enter through the three holes, becoming trapped inside. The narrow hole design makes it difficult for them to exit, allowing you to remove the trap and dispose of the collected pests safely.

Q: Is this trap safe to use in a cherry shrimp or planted tank?

A: Yes! The glass trap uses no chemicals and poses no risk to shrimp, small fish, or aquatic plants. Its hole sizing is designed to allow small shrimp to avoid entering while targeting pest species, making it ideal for delicate nano and shrimp tanks.

Q: How do I clean the glass planarian trap after use?

A: Cleaning is simple — remove the trap from your tank, dispose of the captured pests, and rinse the glass tube under warm running water. Use the included cleaning tool to clear any residue from inside the tube. Allow it to dry or reuse immediately with fresh bait.

Q: What types of pests can this trap catch?

A: This versatile trap is effective against planarians (flatworms), leeches, bristle worms, snails, and other small aquarium pests that are drawn to bait. It is a great all-in-one pest management tool for freshwater aquariums.
