Buying Guide

Match agent to target pest

Choose nematodes for soil-dwelling larvae, predatory insects like ladybugs for soft-bodied pests, and repellents or systemic implants for vertebrate or tree-specific issues

Consider application environment

Pick greenhouse- or indoor-safe formulations (e.g., Scanmask nematodes) for container plants and outdoor-specific products for garden beds and trees

Check delivery format and timing

Live insects require immediate release and temperature control, while nematode suspensions and implants have defined application windows and set-up needs

Evaluate pet and ecological safety

Favor biodegradable, natural-oil repellents for yards with pets and verify that biological controls are appropriate for local beneficial species

Compare multi-strain vs single-strain mixes

Triple-blend nematode packs cover a broader range of soil pests, whereas single-strain products may be optimized for specific pest biology
