I made the mark to look like the leaves in circle and it's cut in 3 places like the signal light on the device.

I focused to find the right typography and I think I managed to find the right one that will differentiate your product from your competitors. Also, I used small letters to make it more friendly so it can cares the message that will not hurt nether family that is using it in the house nor the pests.

Both mark or typo look very good on the device. The device looks premium and high quality.
