Syngenta formulated this granular bait with 0.22% Indoxacarb, a non-repellent active ingredient that ants cannot detect. They carry it back to the nest willingly, and the MetaActive effect ensures the toxin only activates after ingestion by target pests, reducing risk to non-target organisms. The 1-lb shaker bottle lets you apply a precise perimeter band around the foundation.

Real users report that ants began dragging the granules within two minutes of application, and colonies were wiped out in two days. One professional pest control technician confirmed it works on all ant types indoors and outdoors, as well as seasonal ground beetles and box elder bugs. Southern Louisiana users noted fire ants took the bait over a week, but every mound in the yard died.

Keep the granules away from pets and children during application — the smell can repel animals, which is actually a useful safety feature. For a mid-range price, you get professional-grade colony elimination that outperforms most retail granular baits.

Talstar PL is the longest-residual granule on the market, with a sand-core structure that penetrates mulch and grass without needing watering. A single broadcast application provides two to four months of protection against ants, fleas, and other outdoor insects. The 400-ounce bag covers large properties efficiently.

User reports highlight its reliability for cutter ants — they disappeared by the next day after application. One reviewer with a 20-year ant problem on their property found that combining these granules with Talstar liquid (1 oz per gallon) kept ants away for two months after a two-week elimination period. The granules also kill crickets, earwigs, and black widows, making it a broad tool for yard management.

This is the premium option for homeowners who want a set-it-and-forget-it treatment. It requires no mixing and resists rain, but the upfront cost is higher than most single-season products. For large lawns or persistent infestations, the residual value justifies the investment.

This 1% Cyfluthrin dust is the go-to for treating wall voids, siding gaps, and attic spaces where ants and wasps nest. As a contact dust, it works on contact and leaves a residual that lasts as long as it stays dry. The low-odor, non-staining formula means it won’t discolor siding or concrete.

Users have found it devastatingly effective for wasp and hornet nests — a single dusting eliminated larvae within 24 hours. One reviewer dusted their entire house perimeter and woke up to thousands of dead bugs including roaches and black widows. Note that the bottle does not include a puffer; you will need a separate dust applicator to reach into cracks effectively.

This is not a bait — it does not rely on ants carrying poison back to the colony. Instead, it kills every insect that walks through it. Use it for targeted void treatments and perimeter dusting where you can keep it dry. It is not ideal for open lawn broadcasting.

Sevin’s perimeter granules are a traditional choice for vegetable gardens and ornamental beds. They kill over 100 listed insects both above and below the soil surface, and the fast-acting formula protects for up to three months. The 3-pound bag is generous for garden row treatments.

Real-world users in wooded areas report that this product solves their yearly ant problem, protecting cherry trees and garden beds from infestations. One reviewer noted ants disappeared completely after application, and the granules are easy to spread with a broadcast spreader or by hand. It works on lawns, fruit and vegetable gardens, and around the home perimeter.

This is a mid-range option that balances broad-spectrum coverage with a reasonable application window. It is not a bait — it kills on contact and through ingestion. Water it in lightly if rain is not expected within 24 hours for best activation.

TERRO liquid baits use a sodium tetraborate decahydrate (borax) formula that sweet-eating ants cannot resist. The liquid stays moist for weeks, allowing worker ants to carry it back to the colony and eliminate the queen. This 3-pack includes 18 bait stations, making it easy to place along baseboards, patios, and garden paths.

Users report that sugar ants and carpenter ants swarm the stations within hours, and the colony is dead within days. One reviewer switched from Raid traps to these and saw their ant problem vanish completely in a single day. The clear stations let you monitor bait consumption, and they are EPA-registered for indoor and outdoor use.

Some users note that the liquid can spill if the station tips over, creating a sticky mess. Place them on flat, sheltered surfaces outdoors. This is a mid-range solution that excels for sweet ants but may not attract protein-feeding species like fire ants.

This granular bait is designed specifically for fire ants. The active ingredient kills worker ants slowly, giving them time to take the bait back to the mound and feed the queen. One application controls fire ants for three months, and no watering is required — just sprinkle four tablespoons around each mound in the early morning or evening.

Users emphasize that you should sprinkle the granules around the mound opening, not on top of it, because the ants treat the pile as an attack and refuse the bait. Applied correctly, it eliminates the colony in 48 hours. The large granules do not blow away in wind, and the product is odorless, making it comfortable to use around the yard.

This is a specialized product that excels for fire ants but may not attract other ant species. Use it for targeted mound treatment rather than perimeter broadcasting. For mixed ant problems, combine with a general-purpose perimeter granule.

PIC HomePlus uses four different food-source baits in child-resistant, durable metal stations. The metal construction resists dog chewing and weather better than plastic stations. Place them under rocks or along patios, and the bait starts killing worker ants within 24 hours.

Users have relied on these stations for years — one reviewer reported that the same product kept ants away for three years before needing a replacement. The stations survive heavy rain and last from spring to fall. They are also free of the seven main allergens, a notable consideration for sensitive households.

These are an entry-level solution best for maintaining low ant pressure around the home. The metal cans are a practical upgrade over flimsy plastic traps, but the bait itself is less potent than the granular or liquid alternatives. For light infestations or seasonal prevention, they offer good value in a convenient six-pack.
