Rodent Deterrent Device For 40x30 Barn/Shop For Storing Classic Cars

Published 09/22/2025

Question:

I’ve got both a detached garage and a 40x30 barn where I store two classic cars. Would one MouseBlocker 360x MB64FR be enough, or should I run multiple units?

Alan, the 360x # MB64FR covers up to about 1,000 sq. ft. in all directions, so it should handle most garages or smaller barns on its own. Your barn is about 1200 sq ft so it's a bit over it's tested limit. For a larger open barn with stalls or partitions, I’d recommend two units - one near each vehicle since ultrasonic sound doesn’t pass through walls or solid objects well. The nice thing is the 360x is built for tough spaces IP55 rated, weather-resistant housing, so it’ll handle barn conditions just fine.

How is your barn set up? One big open space or multiple sections?
