DON'T DO IT! Check the reviews from verified purchases
When I plugged these in and turned them on, my ears were immediately flooded with a super high pitch sound. The sound is audible in both the high and medium settings, and only my children were able to hear the low setting. These are NOT ULTRASONIC. I contacted the vendor and received this reply, "It is normal to have sound, it will not be harmful to the human body, you can use it with confidence."What an idiotic response. Regardless if it works on rodents, it would flush my family from our home in minutes. Apparently, they don't understand the definition of "ultrasonic".My only regret is that I have to give this product one star to post the review. Zero should be an option for products like this.

Warning reviews are for different product, the 6 pack bug repel ultrasonic plugs are no good!!!

Horrible product
Nothing like description. You can hear the sound & it's annoying so they couldn't be used. I would be 0 stars if that were an option.
