Ultrasonic = modern snake oil! Rats hear up to 76kHz but ignore non-threatening sounds. My IR cameras show them sleeping 2ft from ‘repellers.’ Use snap traps + exclusion instead.
Bats crashed into windows from ultrasonic interference! Fined $1k under Endangered Species Act. Switched to predator decoy rotation, works better and supports local owls.
Combined ultrasonic + ammonia in barns. Works 3x better than either alone! Rats hate sensory overload. Cattle unfazed. DIY recipe: 10% ammonia, 90% false hope.
Landlord installed $50 Amazon specials. Rats partied HARDER, chewed through repeller wiring to build nests. Now suing for ‘fraudulent pest control’ under state §14-332.
@TechBroScience Your AI repeller’s 18kHz is audible to teens! No wonder dogs panic. Real solution: Multi-sensory assault (light + sound + vibration). $1.2k systems work… until rats evolve.
