These are not very good at all don't buy them

2 plug in pest repellers that work with ultrasonic changing frequencies that emit a blue light for a wider range. They have 45 bands from 22-60k of ultrasonic frequencies that change automatically every 2 seconds when the units are turned on. The changing frequencies are shown in the led digital display panel on each plug. This prevents the pests from adapting & becoming used to the signal. They will repel spiders, ants, fleas, mice, ants, flies, mosquitoes & other bugs within 2-5 weeks and are effective on an area of 1300 sq.ft. They wont harm people, elderly, babies, children or your pets and are much safer than using insecticides and chemicals. They arent toxic & dont emit radiation, so are safe to use around food in kitchens, dining rooms etc as there is no bait or poisons like when u use traps. U can use at home or in schools, restaurants, warehouses, offices etc. The blue light can be adjusted from 3 levels of brightness so u can dim it at night if used in a bedroom. They are simple to use, u just plug them in at any mains socket and press the button on the front to turn them on and thats all there is to it.

It did drastically reduce the amount of flies coming in but there is always one persistent one

Still vet flies
