Buying Guide: Key Purchase Considerations
- Target pests: Identify the most common insects in your area to choose an insecticide with proven effectiveness against them.
- Application type: Ready-to-use sprays are convenient, while concentrates offer cost efficiency and flexible mixing.
- Site and plants: Consider whether you need coverage for vegetables, ornamentals, or lawns, and whether pollinators or pets are present.
- Safety and handling: Follow label directions, wear protective gear if recommended, and avoid spraying during bloom or high wind to protect beneficial insects.
- Environmental impact: Pyrethrins are biodegradable but can affect non-target insects if misapplied; plan timed applications to minimize disruption to pollinators.
