Why do rats not like ammonia?

GeneralClass 12AllAnswered 27 Mar 2026
Answer

Rats find ammonia's strong, pungent smell overwhelming and irritating to their sensitive respiratory systems. The odor mimics predator urine, triggering their natural avoidance instincts. Many people use ammonia as a rat deterrent, though its effectiveness is temporary as the smell dissipates quickly outdoors.
