Buying Guide: Key Purchase Considerations
- Target pests and life cycle: Choose products that attack both adults and eggs or larvae to reduce reinfestment. Biological controls like nematodes work on larvae in soil, while sprays target adults on contact.
- Indoor vs outdoor use: For indoor plants, prioritize non-toxic or plant-based formulations with low odor. Outdoors may tolerate stronger or broader-spectrum sprays, but safety remains important around people and pets.
- Safety and pet/kid considerations: Read labels for warnings and reentry times. Plant-based and natural oils generally reduce chemical exposure.
- Coverage area and application method: Ultrasonic or plug-in devices cover larger rooms without chemicals but require placement planning. Sprays and nematodes require dose accuracy and timing with plant watering or soil conditions.
- Speed of relief vs long-term control: Sprays provide quick knockdown, while biologicals and nematodes deliver ongoing suppression over weeks.
- Environmental impact: Favor solutions with minimal impact on beneficial insects and ecosystems, especially indoors where ventilation is limited.
