Spectracide TRIAZICIDE Insect Killer Granules

Gamma-cyhalothrin at 0.05% concentration delivers the fast knockdown that sets TRIAZICIDE apart from competitors. While other brands like Ortho rely on slower-acting bifenthrin, Spectracide’s Bug Stop uses gamma-cyhalothrin for quick knockdown of pests.

The granular formulation kills over 100 insect types both above and below ground — including the grubs that liquid sprays can’t reach. Montana’s short application window demands products that work season-long, and TRIAZICIDE claims up to 3 months of residual control.

Coverage That Makes Economic Sense

Rural Montana properties need coverage rates that don’t break the bank. TRIAZICIDE delivers with a 2 lb per 1,000 sq ft application rate. Here’s what that means for your acreage:

Bag Size	Coverage	Best For
10 lb	12,500 sq ft	Small residential lots
20 lb	25,000 sq ft	Half-acre properties
35.2 lb	44,000 sq ft	Full acre coverage

The math works out better than most liquid concentrates. Granules provide deeper penetration for sub-surface pests compared to most ready-to-spray liquid counterparts. You’re not just treating the surface — you’re getting down where the grubs live.

Application That Actually Works

Apply to a dry lawn using a broadcast or rotary spreader, then water in lightly (1/4 - 1/2 inch) immediately after application. That watering requirement isn’t optional — it’s what activates the product and drives it down to grub level.

Spreader settings matter. Set your Scotts Standard or EdgeGuard to 3, or your Sta-Green to 3. Too heavy and you’re wasting product. Too light and you won’t get the control you need.

Apply in early morning or late evening when insects are active. Middle of the day in July heat? You’re wasting your time and money. Keep children and pets off the treated lawn until the product has been watered in and the grass is dry.

The Reality Check

Users generally praise its effectiveness against ants and its ease of application with standard spreaders. Some mixed reviews mention lower efficacy for heavy tick infestations without repeat treatment. That’s honest feedback — if you’re fighting a serious tick problem, plan on multiple applications.

The product specifically excludes harvester and pharaoh ants from its season-long control claim. Those species need different chemistry. But for the pavement ants, field ants, and carpenter ants that plague Montana properties? It works.

Safe for all established common lawn grasses, but not for use in edible gardens or on food crops. Keep it on the lawn and landscape beds where it belongs.

Bottom Line

TRIAZICIDE earns its place for Montana properties dealing with both surface pests and grub damage. The gamma-cyhalothrin formula at 0.08% in liquid formulations proves the active ingredient works across multiple delivery methods. But for Montana conditions, the granules make more sense — better soil penetration, easier application on large properties, and no spray drift in Montana wind.

FAQ

Does TRIAZICIDE really control ants for a full season?

The product claims season-long ant control, excluding harvester and pharaoh ants. In Montana’s climate, that typically means May through September for one application. Heavy infestations might need a mid-season boost.

How soon after application can kids and pets use the lawn?

Keep children and pets off the treated lawn until the product has been watered in and the grass is dry. Figure 24 hours minimum after watering to be safe.

Will TRIAZICIDE kill grubs that are already damaging the lawn?

The product specifically targets grubs in addition to surface pests. The required watering (1/4 - 1/2 inch) immediately after application drives the active ingredient down to grub depth. It’s both preventative and corrective.

What’s the actual coverage from a 20 lb bag?

A 20 lb bag covers 25,000 sq ft at the recommended 2 lb per 1,000 sq ft application rate. That’s just over half an acre — enough for most residential properties with some left over.
