Ultrasonic pest control does it work for weed?

I purchased this ultrasonic pest control thingy that emits sound that irritates bugs and evicts them from their habitat. it says i should see results in 2-3 weeks but i wonder if it would work for spider mites and Gnat flys and all that other unwanted bugs in my garden. it was made for getting rid of roaches,ants,flies,mouse, mosquitoes and any vertebrate laying around. since it can do that I wonder plunging it in my garden will do any good?

Ultrasonics are supposed to increase plant growth. Google that shit. I've been researching "Electro Gardening" for a few weeks now.

Also my garden is a small tent 60 inch high x 19.5 inch deep and 63 inch long it would be awsome to have that place bug free
