Just plug a charger-sized device emitting undetectable sound into the wall, wait about 2 weeks, then BAM, your garage oasis is insect and rodent free without the use of chemical pesticides or inhumane traps. Sounds great! Too bad these devices have never been proven to actually work. But let’s take a look at the theory anyway.</span></p> Mon, 27 Nov 2017 18:17:57 +0000 Cassandra Lee, OSS Intern 6833 at /oss
