When people think of "wildlife control," they usually picture a cage trap. While trapping is sometimes necessary, the preferred method for modern, humane wildlife control is the **One-Way Door (Excluder)**. This device allows animals to leave your home on their own terms but physically prevents them from getting back in. ## How It Works A one-way door is a mechanical tunnel installed directly over the animal's entry hole. It has a torsion-spring door or a gravity flap inside. 1. **The Exit:** When the squirrel or raccoon inside the attic gets hungry, they approach the hole to leave. They push against the flap, which opens easily from the inside. They walk out onto the roof. 2. **The Lockout:** Once they exit, the door snaps shut behind them. When they return, they find a metal barrier. They can push, pull, and scratch, but the door will not open from the outside. ## Why It's Superior to Trapping * **Low Stress:** The animal isn't confined in a cage for hours waiting for a technician. They simply go outside and realize they can't get back in. * **Keeps Families Together:** For mobile families (older kits/pups), they all exit one by one and stay together outside, rather than one getting trapped and separated. * **Efficiency:** It works 24/7. We don't have to rely on bait that the animal might ignore. ## The Critical Rules One-way doors cannot be used in every situation. 1. **Baby Season:** We **never** use one-way doors if there are flightless babies inside. This would separate the mother from her young, leaving the babies to starve. We always inspect for babies first. 2. **Seal the Rest:** If we install a door on the main hole but leave a gap on the other side of the roof, the animal will just find the other hole. Total home exclusion (sealing all other gaps) is required for this to work. 3. **Species Specific:** A bat cone works differently than a raccoon door. Using the wrong size can trap the animal inside. At HWCS, we prefer exclusion whenever possible. It solves the root problem (the hole) and treats the animal with respect.
