Medication details

The Jungle Formula refill is an insecticide designed to be used in conjunction with the Jungle Formula plug-in device, effectively repelling mosquitoes and other biting insects throughout the night. It is an ideal choice for individuals traveling to regions inhabited by such insects. The Jungle Formula plug-in features a two-pin socket, making it compatible with numerous popular holiday destinations. With this refill, you can enjoy up to 45 nights of protection.

Using Jungle Formula Refill is a straightforward process that ensures maximum protection. Follow these steps for effective application:
Ensure your Jungle Formula Plug-in device is turned off.

Remove the refill cap by holding the bottom of the refill unit and twisting the cap gently.
Insert the refill unit into the device, aligning the cap with the nozzle opening.

Insert the plug into an electrical socket and turn the device on using the appropriate settings for your environment.

The device will release a continuous vapor that offers long-lasting protection against insects. Keep the device plugged in for uninterrupted defense.

For optimal results, place the Jungle Formula Plug-in device near open windows and doorways, allowing the vapor to spread evenly and create a protective barrier.


Jungle Formula Refill contains a scientifically formulated blend of active ingredients designed to deter insects effectively. The key active ingredient is Prallethrin, which is renowned for its insect-repelling properties. Prallethrin works by disrupting the nervous systems of insects, preventing them from landing on or biting treated areas. This potent formula ensures that you remain guarded against insect bites, providing peace of mind during your outdoor activities.
