Buying Guide: Practical Considerations For Beneficial Bugs
What pest pressures exist in your space? Choose nematodes for soil-dwelling pests and soft-bodied above-ground pests for mites and aphids. Consider your climate, soil moisture, and plant types when selecting a product.
- Soil vs. foliar targets: Nematodes work underground; ladybugs and mites target above-ground pests.
- Preventive vs. curative: Slow-release sachets provide ongoing defense; releases after infestation may require more frequent applications.
- Storage and handling: Some products need refrigeration or timing with watering schedules; follow label directions for best results.
- Release strategy: Space out releases to maintain population levels; avoid overcrowding and ensure even distribution.
- Safety: Beneficial insects are generally safe for humans, pets, and plants, but avoid releases during extreme heat or cold that could reduce survival.
