Cotton Balls
High quality, organic cotton balls for use with test tubes. These plug the opening of the tube, keeping ants contained while allowing airflow — the same cotton balls we use for all of our test tube colonies, and a perfect fit for our standard 16mm test tubes.
Recommended Accessories
The standard tube size across all TrapJaw gear. These cotton balls are sized to fit them.
Required
Seals the water reservoir at the back of the tube. Pair with a cotton plug at the opening for a complete setup.
Optional
Keeps tubes from rolling and connects them to nests and foraging areas via vinyl tubing.
