Variable sonic waves, at the right frequency and with the correct waveform, ensure an excellent repellent effect, especially against mosquitoes. As they are slightly audible, you can adjust the intensity to 3 levels according to your preference.

If used indoors, especially in the bedroom, it is recommended to set the device to maximum intensity before going to bed and to minimum once in bed.

COMPLETE PROTECTION
The Colpharma repellent range protects environments, people and pets from mosquitoes, , parasites, insects and rodents.

DOUBLE DEFENSE MOSQUITO REPELLENT: FREE TO CHOOSE YOUR PROTECTION!
Does the slight whistling of sonic mode bother you? Use low sonic mode or ultrasonic mode.

Are you outdoors? Use high sonic mode.

The slightly audible sonic emissions are effective against mosquitoes because they reproduce the call of the male mosquito, driving away the female—the one that bites and seeks blood for her eggs. They have a greater repellent effect than ultrasonic emissions, but may be audible to some people and therefore cause discomfort.

Ultrasonic mode cannot be heard by the human ear, but is less effective and has a shorter range than sonic mode.

From now on, with Colpharma DOUBLE Defense, you can choose which of the 2 modes you prefer to best meet your needs!

Colpharma DOUBLE Defense uses 2 combined repellent technologies: sonic emissions (2 intensity levels) or, alternatively, ultrasonic emissions.
