CimoroWin Bat Exclusion Tubes — 2-Pack Black One-Way Polyethylene Cylinders, Reusable 5.7x2in

The CimoroWin 2 Pcs Bat Exclusion Reusable Tool is a simple polyethylene one-way tube that lets bats exit an attic or enclosed space while preventing re-entry.

If bats are finding their way into your attic, crawl space, shed or garage, a one-way exclusion device offers a low-impact, low-cost way to encourage them out without trapping or harming wildlife. The CimoroWin set includes two compact black polyethylene cylinders designed to be mounted over a bat entry point at a downward angle so animals can leave but not return. Built for repeated use and straightforward installation, these tubes work with common fasteners (not included) and are sized to fit most small access gaps.

How does this device stop bats from coming back?

Installed at a steep downward angle, the cylinder creates a one-way exit path. Bats fly out through the tube but cannot navigate back through the same opening because of the tube’s shape and positioning. This method relies on behavior rather than chemicals or noise.

• One-way polyethylene cylinder prevents re-entry when angled properly
• Recommended installation angle greater than 60° for best effect
• Works passively—no power, bait, or harmful agents required
• Durable material withstands outdoor conditions for repeated use

What’s involved in installing the CimoroWin bat exclusion tube?

Installation is quick and requires only basic tools and fasteners; U-type nails, silicone or tape are suggested but not included. Position the tube so the opening points downward, secure it over the bat entry gap, and seal around the mounting point to guide bats out through the cylinder.

• Compact size (about 5.7 x 2 inches) fits most small entry gaps
• Lightweight (≈30 g) minimizes stress on mounting surface
• Use nails, adhesive, or tape to hold cylinder firmly in place
• Trim or adapt mounting area as needed to achieve a >60° angle

How durable and reusable is this bat exclusion tool?

Made from polyethylene plastic, the CimoroWin cylinder is designed to resist wear, allowing repeated use season after season. The material tolerates typical outdoor exposure, and the compact form makes storage and relocation simple for future needs.

• Polyethylene construction resists cracking and moisture
• Reusable design—remove and reinstall at new openings
• Black finish blends with shingles, soffits and dark spaces
• Pack of two lets you tackle multiple openings or share with others

Who is this for? Homeowners, DIYers, property managers and small-business owners who prefer a humane, non-lethal option for removing bats will find the CimoroWin bat exclusion tubes practical and affordable. If you need a compact, reusable one-way exit device for attics, crawl spaces, sheds or garages—and are ready to follow local wildlife regulations about bat exclusion—this two-pack offers two ready-to-install cylinders that work with common mounting materials.
