Insect control devices use ultraviolet light to attract flying insects and neutralize them either through an electrically charged grid or a sticky surface. UV tubes attract flying insects by emitting UV light waves in the range of 350–368 nm. These tubes produce UV light that is comparable to sunlight, and insects are naturally drawn to sources of light and heat.

It is very important to choose the right device according to the user's needs. Each device has specific characteristics based on the area it covers, depending on the intensity of the UV light it emits, the installation method, and its design. In general, zappers (devices with an electrically charged grid) are recommended for entrance areas with a high number of flying insects, while devices with a glue board are preferred for sensitive areas where food is prepared, served, or displayed. Entrances often require decorative units that offer discreet yet highly effective insect control. To help you choose the most suitable device for your needs, we recommend visiting the device selection section on this website.

Since these devices work by attracting insects with UV light, it is very important that the UV light is visible from all angles of the room you want to protect. The device should ideally be installed at a height of at least 2 meters from the floor to ensure it is clearly visible to insects. It is also essential to position the device opposite from sources of natural light, such as windows or doors. In large rooms or those with multiple corners and obstacles, it is recommended to install two or more devices to ensure complete protection against flying insects.

For the devices to function efficiently, regular maintenance is necessary. The lifespan of the UV tubes is around 8,000 hours, so they should be replaced at least once a year, preferably before the start of the summer season. Devices with an electrically charged grid kill insects upon contact with the grid; therefore, it is recommended to use a voltage tester (phaser) to check if the grid is powered. Devices with a sticky surface also use UV light to attract insects but eliminate them by means of the sticky surface, providing a quiet and discreet protection. The sticky surface’s fill level with insect remains should be periodically checked for hygiene reasons. The quality of the sticky surface can greatly affect the device’s efficiency. P+L devices use GLUPAC™ sticky surfaces with UV-resistant adhesive, coated with pheromone, which increases the device’s effectiveness. However, the effective duration of sticky surfaces is about thirty days, so they should be replaced monthly to ensure reliable insect neutralization. Insect destruction devices should be placed in an appropriate location within the room, as described in the previous paragraph.
