Ultrasonic Gecko Repellents: No Evidence They Work

Devices claiming ultrasonic/subsonic sound repels geckos—no peer-reviewed evidence supports efficacy. Most animals can't hear or habituate quickly.

Reality Check

• Animal rights groups don't endorse them.
• icwdm.org/ControlMethods/ultrasound.asp explains the science.
• Urban wildlife adapts to constant noise.

Real Solution

Seal building entry points (1/4" gaps). Spend money on caulk, not gadgets.
