Scat Identification: Long Droppings from Narrow Gap

Extra-long droppings from a 1/16" gap above a doorway suggest mice, shrews, or rats—all can climb and squeeze tight spaces. Insect frass is possible but less likely in that location.

ID Resources

• Visit ICWDM scat identification pages.
• Note: size, shape, ends (pointed/blunt), contents (hair/seeds/insect parts).
• Photo with scale (coin) helps experts.

Quick Clues

• Mouse: 1/4", pointed ends, scattered.
• Rat: 1/2-3/4", blunt ends, clustered.
• Shrew: Twisted, insect parts visible.
• Bat: Crumbly, shiny insect wings, under roost.

If inaccessible, use a mirror/phone camera to inspect gap. Seal after confirming no animals inside.
