The ATRAKTA Mosquito Attractant Pods enhance your trap’s ability to attract and trap insects by using natural scents that mosquitoes find irresistible, a powerful combination of Lactic Acid, Octenol, and Ammonium Bicarbonate. The ATRAKTA Mosquito Attractant Pods come with an adaptor which is designed to fit Mosquito Magnet Traps. The pods can also be used with any outdoor mosquito trap, allowing you to maximize their trapping power. To use, simply open the package, pierce the foil in the cap and insert the pod with adaptor into the trap’s attractant receptacle at the plume tube. If using with a mosquito trap other than Mosquito Magnet, simply open the package, pierce the foil in the cap and place the pod in the catch basket. For the best results, it is recommended to change each pod every 16 days to ensure the attractant is active. Each package comes with 3 ATRAKTA Mosquito Attractant Pods so you have replacements on hand when you need them.
