Do Electronic Pest Control Devices Really Work?

After running a few tests we have found that not all of them do. Here is a list of some negative effects observed.

  • Cockroaches. The research showed that ultrasound does not repel these insects. It only affects their movement patterns making them more erratic. This increases the effectiveness of sticky traps but we don’t recommend you to use the ultrasonic pest repellent as the only defense against cockroaches.
  • Mosquitoes. You can download an app for your cellphone if you want to test the effect of this technology by yourself. This will significantly reduce the number of mosquitoes in the area but if one of them lands on your skin, the ultrasound will not prevent the mosquito bite.
  • Rodents. The ultrasonic pest repellents have powerful effects on rodents. It will make them want to leave the area immediately. However, after a few days, the rodents will get used to the new sound and eventually ignore it. Making them go back to their “homes”. We recommend you to use a device that works using different frequencies so you can get rid of this issue.
