A planaria trap is a safe, chemical-free tool used to catch and remove predatory flatworms from aquariums. Planaria pose a severe threat to shrimp tanks because they secrete toxic mucus that paralyzes and kills baby shrimp, molting adult shrimp, and eggs.

How to Use a Planaria Trap:

• Add Bait: Place meat-based food inside the trap, such as frozen bloodworms, brine shrimp, raw chicken, or fish flakes.
• Fill with Water: Submerge or fill the trap with aquarium water so no large air pockets remain.
• Position on Substrate: Place the trap flat on the tank floor with the entry holes facing directly down against the gravel or sand to keep curious shrimp out.
• Turn Off Lights: Set the trap at night or turn off the aquarium lights, as planaria are nocturnal and active in the dark.
• Empty and Clean: Remove the trap after a few hours or up to 24 hours, rinse out the caught worms with hot water, and repeat if necessary.
