Ortho Orthene Fire Ant Killer Broadcast Granules – Up to 6 Months of Lawn Protection (11.5 lb)

Protect your lawn from fire ants with Ortho Orthene Fire Ant Killer Broadcast Granules. This lawn-friendly granular treatment delivers protection that can span several months, helping you enjoy more time outdoors without the constant worry about new mounds emerging. When used as part of the Ortho 2-Step System, it targets both existing colonies and future reinfestation in your turf.

Why this product stands out

• UP TO 6 MONTHS OF PROTECTION: Keep your lawn shielded from fire ants for half a year with a single treatment, depending on conditions.
• PREVENTS NEW MOUNDS: The granules work to stop new mounds from forming, reducing reinfestation from adjacent areas when the lawn is treated as a whole.
• EXTENDED COVERAGE: One 11.5 lb bag covers up to 5,000 sq ft, making it suitable for larger lawns and yards.
• EASY SPREADER APPLICATION: Use a Scotts drop or broadcast spreader to apply evenly, then water in after application to activate the product.
• OUTDOOR USE ONLY WITH SAFETY GUIDANCE: Use outdoors; re-entry is permitted after the granules have been watered in and the area dries.
• 2-STEP SYSTEM INTEGRATION: Pair with Ortho Orthene Fire Ant Killer (Step 1) to destroy existing mounds before applying Step 2 for ongoing protection.

How to use for best results: Apply when ants are most active—typically in the morning or late evening—when temperatures are between 65°F and 80°F. Watering after application helps the product reach the soil and roots where ants forage, supporting the coverage claim across your lawn. This is designed for outdoor lawns and can complement routine yard maintenance, helping you keep playgrounds, patios, and garden beds safer and more enjoyable.

Real-life use cases

Imagine a weekend lawn project with visitors enjoying the shade while ants are less visible in the morning after a light dew. Or a quiet evening when you’re prepping the yard for barbecues and want to reduce the chance of new mound formation. With up to six months of protection, you may spend fewer weekends wrestling with mounds and more time relaxing on your lawn.

In short, Ortho Orthene Fire Ant Killer Broadcast Granules offer a practical, lawn-focused solution that can help curb new mounds and extend protection across a sizable area, all while fitting into a two-step approach designed for ongoing control. Results can vary with environmental conditions, but many users appreciate the straightforward application and broad coverage.
