Buying Guide: How to Choose the Right Lawn Granule Insect Killer
What size lawn do you have? For smaller yards, 10–16,500 sq ft granules may suffice, while larger properties benefit from 20–33,000 sq ft bags. Consider pest scope: simple ant or grub problems may be solved with a targeted formula, yet broad-spectrum options handle multiple pests. Look for products with fast action, residual protection, and clear activation instructions—most require watering in after application.
Spreader compatibility matters. Use a Scotts or compatible broadcast spreader for even coverage and follow label rates to avoid under- or over-application. Remember to water after spreading to activate the product’s effectiveness, and reapply according to the product’s protection duration.
Safety and pets: Keep children and pets away during application and until granules have been watered in and are dry. Some products have restricted use around edible gardens; always check the label for specific guidance.
Frequently Asked Questions
