Scotts Turf Builder SummerGuard Lawn Food with Insect Control, 5,000 sq. ft.

This product blends lawn food with insect control, designed to feed and strengthen across heat and drought. It’s best for small-to-midsize yards where homeowners want both feeding and pest protection in one application. It’s recommended for homeowners seeking a simple, guaranteed-to-not-burn solution, particularly in hot climates. A limitation is the 5,000 sq. ft. coverage, which may require multiple bags for larger lawns. Best for: small lawns needing proactive protection and robust feeding.
Scotts Turf Builder SummerGuard Lawn Food with Insect Control, 15,000 sq. ft.

Designed for larger lawns, this option provides a broad shield against listed bugs while feeding the turf to withstand heat and drought. Choose this if you need extended coverage for bigger properties or multiple zones. The product is best for homeowners who want a single product for regular feeding plus insect protection. Limitation: larger bag size may be harder to measure for small lawns.
Scotts Turf Builder SummerGuard Lawn Food with Insect Control, Fertilizer & Insect Killer, 5,000 sq. ft., 13.35 lbs. (2-Pack)

This two-pack combines fertilizer with insect control for two treatments across a season. It’s best for homeowners who want periodic protection and growth support without purchasing separate products. Better for smaller to mid-sized lawns that need recurring applications. Caution: ensure proper application in dry conditions and avoid over-watering immediately after use.
Atticus Asenra SRX (4 OZ) Liquid Grub Control for Lawns

Asenra SRX is a liquid grub control with broad action against white grubs, caterpillars, armyworms, and more, lasting up to 120 days. It’s best for those who want season-long protection with a single concentrate that can cover multiple pest types. Choose this if you prefer a versatile, one-jug solution for lawns and landscapes. Limitation: follow label directions closely to avoid over-application and ensure site suitability for use in beds and ornamentals.
Note: Compare Coverage And Application Timing
When selecting a product, match the coverage area to your lawn size and consider the pest pressure you face. Grub-focused products like BioAdvanced and Atticus provide longer seasonal protection, whereas Scotts options emphasize heat/drought resilience with built-in bug control. For small yards, the 5,000 sq. ft. products are typically easiest to manage, while larger properties benefit from 15,000 sq. ft. coverage or multi-pack options.
Buying Guide: Armyworm Control In Turf
What should I consider before buying?
- Coverage area: Match the bag size to your lawn size to avoid waste or multiple applications.
- Active pests: If armyworms are the primary issue, prioritize products labeled for armyworms or general turf pests.
- Season length: Some formulas offer season-long protection, reducing the need for frequent applications.
- Site needs: For landscapes with bed borders or ornamentals, consider products labeled for use around gardens and bulbs.
Best for small lawns vs. large properties
Small lawns benefit from 5,000 sq. ft. options that are simple to apply, while large properties gain efficiency from 15,000 sq. ft. formulations or multi-pack sets. Consider whether you need a combined fertilizer and pest control or a dedicated grub or armyworm treatment.
When to apply?
Apply at the first sign of pest activity or when grub damage is suspected. For season-long products, a single application in the early growing season can provide ongoing protection. Always follow label directions for timing and application conditions, such as temperature and moisture.
Safety and compatibility
- Follow label directions for pet and child safety, watering, and mowing after application.
- Avoid applying during extreme heat or drought conditions if guidance specifies limits.
- Check compatibility with existing lawn care products to prevent burn or reduced effectiveness.
