The heaviest hitter that covers the most ground in a single pass.

You get the widest coverage here: a 20-pound bag that treats up to 25,000 square feet. That is double the weight of the BioAdvanced Season Long Grub Control (10 pounds) and covers a much larger area. The fast-acting formula kills listed insects on contact, including grubs, ants, ticks, and chinch bugs, all from one spread-and-water application.

Buyers report it provides “~3 months of pest protection in warm climates” and confirm it is safe for St. Augustine grass. One reviewer noted the formula didn’t eliminate the food source for moles — moles kept digging on treated turf. Another noted that stink bugs walked right through it, so this is excellent for grubs and most lawn pests but not a silver bullet for every insect.

If you want the biggest chemical blanket for the largest yard, this is it. Compared to the Season Long Grub Control, the Complete Insect Killer is a 20-pound bag (a 2.0x weight gap) with triple-digit coverage.

One spread that creates a barrier all season against 40 lawn pests.

This uses Lambda-cyhalothrin, a synthetic chemical that kills listed insects above and below the surface. The brand claims a single application protects all season long by creating a barrier that kills grubs, mole crickets, chinch bugs, ants, ticks, and more — the label claims it works on 40+ destructive lawn insects. At 10 pounds, this is the smallest bag from BioAdvanced, making it a better fit for smaller yards.

This is the chemically intensive approach. Owners mention it is extremely effective for Japanese beetles — one buyer mentioned applying it in spring and “for the first time ever, no beetles” on their roses through end of June. However, a buyer warned that after purchase they found it should not be used around edible plants. If you have a vegetable garden or fruit trees nearby, this is a real caution.

For a smaller chemical killzone that targets grubs and beetle larvae, this is the right size compared to the 20-pound Complete Insect Killer. You trade coverage for targeted power at half the weight.

A granular premium option that handles grubs and visits from sod webworms.

This 15-pound bag treats up to 5,000 square feet of lawn or flower beds, targeting grubs, mole crickets, and other listed insects. You can apply it spring through summer for best results before grubs and mole crickets hatch. It kills and repels grubs all season long and works for a broader list of pests: one buyer used it specifically to control a sod webworm problem.

The main complaint from buyers is not about the formula but the packaging — shipping labels and stickers covering the back instructions were hard to remove. If you buy this, look up the label online or peel carefully. One owner reported it was effective at a quarter of professional cost and that they will repurchase.

This is more expensive than the BioAdvanced Season Long Grub Control, but customers note it handles sod webworms, which the Season Long Grub Control does not list.

The low-maintenance natural defense that lives in the soil for a decade and a half.

This is the biological approach at scale. The active ingredient is Bacillus Popilliae, a natural bacteria that infects and kills Japanese beetle grubs without harming pets, beneficial insects, or wildlife. Once established, the spores multiply in the soil and provide protection for up to 15 years. The 15-pound granular bag is easy to spread with a standard spreader — simply apply in spring, summer, and fall for two years, after which the spore population becomes self-sustaining.

Shoppers say it is effective but requires patience. One reviewer wrote “it’s very easy to use, just put it in a spreader” and noted it didn’t harm plants or bushes. Another said “this is the only thing that gets rid of Japanese Beetles and it is natural.” The honest trade-off: you won’t see dead grubs immediately. You must reapply three times a year for two years before the soil is fully colonized. It is also the most expensive upfront option at the 15-pound size.

Compare this to the BioAdvanced Complete Insect Killer: chemical control kills today and lasts one season; this costs more now but eliminates yearly chemical purchases for over a decade.

The entry-level spore bag that teaches you the biological method on a smaller patch.

You get the same Bacillus popilliae bacterial technology as the 15-pound granular, but in a concentrated powder form. At 11.2 ounces (10.0 Ounce unit count), one bag covers up to 2,500 square feet when applied as 1 teaspoon every 4 feet along rows. You can apply it by hand, or use a Milky Spore Dispenser Tube (sold separately). The reward is the same lasting protection: once the spores are in the soil, they multiply and stay active for years, providing ongoing grub control season after season.

Buyers warn that powder is extremely fine — open it carefully. One customer observed it is “expensive and requires multiple applications BUT it works” and reported no grub or Japanese beetle problems after a year of use. Another user mentioned mixing it into new soil during reseeding to avoid burning. The 10.0 Ounce unit count means it covers a fraction of the area compared to the 240.0 Ounce granular bag (a 32.0x gap).

If you are testing the biological method for a small garden patch or a flower bed, this is a lower-cost entry point. Compare its 2,500 sq ft coverage to the 15-pound granular version’s broader area — the powder is the better starter size.
