The new MR450 repeller from Thermacell Repellents establishes a 15-by-15-foot zone of protection from mosquitoes and other flying insects.

A butane cartridge heats a repellent-soaked mat — silently and without odor or an open flame — to disperse vapor around you. The repellent mimics the natural one found in chrysanthemum flowers. An accessory mounting system allows you to attach the MR450 to a belt clip or multipurpose clamp. $34.99. Thermacell Repellents, Bedford, Massachusetts, (781) 541-6900. thermacell.com
