Scotts GrubEX1 Season-Long Grub Killer 2-Pack (28.7 lb each) — One-Application, 4-Month Protection

Scotts GrubEX1 Season Long Grub Killer is a single-application granular treatment that kills and prevents grub infestations for up to four months.

Lawns can quickly decline when subterranean insects feed on roots and crowns. Scotts GrubEX1 delivers a season-long granular solution you apply once in spring or early summer; then water to activate. Each 28.7 lb. bag treats about 10,000 sq. ft., and this listing includes two bags for larger properties or repeat coverage next season.

How long does protection last after application?

A single properly timed application provides control for up to four months, covering the critical period when grubs and many turf pests are actively developing. Timing the treatment in spring or early summer ensures the active ingredient intercepts larvae before they cause root damage.

• One application lasts up to 4 months
• Best applied in spring/early summer when grubs develop
• Water in immediately after spreading to activate
• Each 28.7 lb bag covers roughly 10,000 sq. ft.

Which pests will this product control?

GrubEX1 targets several turf-damaging insects beyond white grubs, helping prevent the brown patches and thinning turf that result from root feeding. Consult the product label for the full list of covered pests and application specifics.

• Kills and prevents common grub species
• Also effective against armyworms and sod webworms
• Controls chinch bugs, May/June beetles, and Green June beetles
• Can help reduce Japanese beetle pressure when used annually

How do I apply Scotts GrubEX1 for best results?

Apply the granules to a dry lawn using a compatible spreader, then water thoroughly to move the active ingredient into the soil where larvae feed. Re-entry by people and pets is allowed once the lawn surface has dried, but always follow label safety directions.

• Use a Scotts broadcast, drop, handheld, or Wizz spreader for even coverage
• Apply to dry turf and water in immediately to activate
• Allow treated areas to dry before allowing foot traffic or pets
• Follow label for rate, safety, and local restrictions

Will this harm my lawn or beneficial insects?

When used as directed, Granular GrubEX1 is formulated to target soil-feeding larvae while minimizing stress to established turf. Because it affects a range of soil and surface pests, avoid off-target application and follow all precautionary statements on the product label to reduce impacts on non-target organisms.

• Designed to protect turf by preventing root damage
• Apply only at recommended rates and timings
• Avoid drift onto flower beds and water bodies
• Read label for specific precautions about non-target species
