The clearest example on this shelf of a product whose name promises a job its chemistry is not the recommended tool for.
The bag says Season Long Grub Control. The active is lambda-cyhalothrin, a synthetic pyrethroid — and the extension guidance we rely on does not put the pyrethroids in the grub column. Penn State lists them for ADULT scarab beetles feeding on foliage rather than for larvae, because pyrethroids are contact insecticides that bind tightly to thatch and soil organic matter and lose activity before reaching something feeding inches down. To be fair about what we do and do not know: the product is EPA-registered, and registration means efficacy data was submitted for its label claims. So we are not telling you it does nothing. We are telling you that the university turf programs recommending actives for white grubs name anthranilic diamides and neonicotinoids for prevention and organophosphates for cure, and this is none of those. For surface pests — the mole crickets and chinch bugs also on the bag — it is a reasonable granular product at a fair price.
Our rating above is what it is. If the limits we describe rule this out for your lawn, these rate higher for the same job — read them before you decide.

The one product on this shelf that extension guidance actually names for grubs — and the one people most often apply too late to work.

The retail trichlorfon product — the active MSU Extension names for CURATIVE grub control, applied late August or early September against grubs already feeding. Its counterpart, chlorantraniliprole, is preventive and belongs in May or June.

Label read on EPA's label database
EPA Reg. No. 53883-223-92564
We opened this product's accepted label on EPA's own Pesticide Product Label System — the strongest source available for what a product is registered to do.
EPA PPLS registry read 2026-08-02. Base registration 53883-223 is 'LAMBDA 0.1% INSECT GRANULES', lambda-cyhalothrin 0.1%, latest accepted label 2026-02-05. The number in this record adds distributor code 92564 (BioAdvanced), so the bottle is a distributor label of that base registration and may print a narrower site or pest list than the base allows. Percentage and active confirmed against the base registration; the distributor's own printed label has not been read.
Where this page and the container disagree, the container wins — the label is the legal authority on rates and restrictions. How to read one yourself.

Named for grubs, but lambda-cyhalothrin is a pyrethroid and extension guidance does not list that class for larvae
The label for BioAdvanced Season Long Grub Control lists Mole crickets, but our rating is 2.6/5 — so read the verdict above before buying. A label listing a use and a product delivering it are not the same claim, and the gap is what our rating is measuring.
The accepted label is linked from this page, and the product is EPA Reg. No. 53883-223-92564 — the number to search if the link ever moves. The label is the legal document; anything on this page that disagrees with it is wrong.

Fertilizer
Your lawn is yellow and nitrogen is only one of nine causes — feeding the wrong one wastes a season. Diagnose by pattern, blade and timing first.

Lawn Diseases
NC State: pesticide applied at any other time will be ineffective. And the cheap bags printing 'grubs' hold pyrethroids, which never reach the larva.

Lawn Diseases
MSU names six actives that should not be used for grub control at all — and some bags sold as grub killers contain exactly those. Two molecules do the work.

Grass Types
Bahiagrass lawn care starts with an honest verdict: NC State rates its turf quality low. Right for a big rural lot, wrong almost everywhere else.

Lawn Diseases
Mole crickets in a lawn are noticed in spring and autumn — the two worst times to treat. The window is small nymphs in June, and a soap flush confirms them.
