Spatial repeller or yard treatment — which should I buy?

It depends on use. Across reviewers, spatial repellers (Thermacell) win for on-demand, seated patio and camping protection in calm air, while yard sprays and larval-control stations aim at reducing the broader population over weeks. Many reviewers combine approaches, but high-trust sources caution that sprays carry environmental trade-offs and traps underperform against mosquitoes specifically.
