Thermacell ER136 Repellent Refill - 36 Hour Mosquito Protection

The Thermacell ER136 Repellent Refill delivers 36 hours of continuous mosquito protection across a 20-foot zone without any odor or mess. This black cartridge refill works seamlessly with Thermacell's rechargeable E-Series and Radius Zone devices, providing reliable insect control for outdoor activities.

What Makes This Different

Unlike traditional bug sprays that require direct skin application, the ER136 creates an invisible barrier of protection around your entire area. The heat-activated allethrin formula disperses evenly through the air, repelling mosquitoes before they can reach you. This system eliminates the need for sticky lotions, harsh chemical odors, or constant reapplication that comes with topical repellents.
