ultra sonic pest control - driving out EHBs

[JohnBeeMan]

Just after setting up a cone trap out, my son ask if one of the ultra-sonic pest control devices would help drive the bees out of the home.My guess is that at most it may shorten the amount of time required to do the trap-out.

I'd always thought those things were snake oil. Some years ago I read a report on them and there was supposedly no conclusive proof they actually worked on pests. If someone can enlighten me (and I don't accept sales & marketing literature as 'proof' on any product) I'd appreciate it.

snake oil.

[BULLSEYE BILL]

I installed one in my tool shed a few years back after having an issue with pack rats. Since then I have not had any rats or mice as evidenced by the lack of interest in the poisons that are also put out.

It did not curtail the carpenter bees, mason bees, or wasps that are mainly on the outside of the building.

Ultrasonic pest control devices have been on the market for a long time. Their manufacturers and sales personnel lead you to believe that the high-pitched sound produced by the little black boxes (some with red lights to show you they are working) can only be heard by pests, not by other animals or humans. The sounds are so annoying, they say, that pests either leave or die. They also claim that the devices won't harm your pets, like gerbils and hamsters.

Not so, say scientists who have worked with these pests and tested some of the equipment.

It's pretty easy to Google up thousands of real university studies on these things.
