Thermacell Patio Shield Mosquito Repellent E-Series Rechargeable Repeller $29 (was $39)

See It

This unassuming little device creates a 20-foot safe zone that mosquitos will avoid with all of their might. It’s a repellent diffuser, which means it disperses a substance the bugs really hate. But, it does so in such a way that it’s undetectable to humans. The Thermacell has a built-in battery that lasts up to 5.5 hours per charge. The refill cartridges last roughly 40 hours each, so you can get tons of outdoor hang sessions out of one cart before you need to restock.
