Buying Guide
- Target pests: Choose nematodes with documented efficacy against the pests common in your area, such as fungus gnats, grubs, fleas, or root nematodes. blends like HB+SC+SF provide broader coverage.
- Form and application method: Liquid blends, granular slow-release, and drenches each suit different garden setups. Consider ease of use, whether mixing is required, and how you water after application.
- Storage and viability: Some products offer refrigerator storage or unactivated viability windows. Plan your purchases around your seasonal pest pressure and field timing.
- Safety and environmental impact: All listed products claim safety for humans, pets, plants, and beneficial insects when used as directed. If you have pollinators or nearby wildlife, prioritize non-toxic options and proper timing of applications.
- Coverage and scale: For larger spaces, higher-concentration packs or slow-release formats help reduce repeated applications. Match pack size to your soil area and irrigation capacity.
- Delivery and packaging: Look for insulated shipping where relevant, especially for live nematodes, to ensure viability upon arrival. Verify supplier credibility and product freshness guarantees.
- Storage after opening: Some products advise refrigeration or refrigeration after activation; others are used immediately. Plan storage to maintain nematode viability until application.
- Integrated pest management: Consider combining nematodes with other non-chemical strategies, such as beneficial insects or cultural controls, to maximize garden health and pest suppression over time.
