This comes in a set of two and is basically built for outdoor use. It not only keeps insects away but also small rodents and animals.
Since this pest repellent is solar powered there is no hassles with wires or batteries.
It obtains and stores its power during the day from sunlight.
It works by emitting a strong ultrasonic signal which scares small animals, birds and insects.
The ultrasonic signals are only audible to small animal and rodents and not to human being. So it is safe to be put around small children too.
It can be used on daily basis in the garden, lawn, backyard or can be taken for camping or trips as it is small. compact and portable. It comes with 2 aluminum spikes to fix it in the ground.
