Buying Guide: Key Considerations For Grub Control
- Lawn size and coverage: Choose products that clearly match your square footage. Large lawns benefit from granules with high coverage per bag.
- Active ingredients and spectrum: If you face multiple pests, consider broad-spectrum granules. For grub-specific needs, focus on products labeled for grubs and related beetle larvae.
- Seasonality and timing: Many products work best when grubs are young or just appearing. Timing ensures maximum effectiveness and minimizes lawn damage.
- Organic vs. synthetic: Organic options like Milky Spore prioritize eco-friendliness but may require more time to show results. Synthetics often provide faster knockdown and longer immediate protection.
- Application method: Spreader compatibility and watering instructions impact results. Some products require irrigation to activate.
- Lawn health goals: If you also want root strengthening, select products that include turf revitalization components or pair with separate fertilization.
