Terro Ant Killer Plus Multi-Purpose Insect Control
Terro Ant Killer Plus is designed for outdoor use and targets a broad range of crawling insects, including ants, fire ants, roaches, fleas, crickets, earwigs, millipedes, mites, palmetto bugs, silverfish, sow bugs, and more. The product offers quick effect, with pests typically dying within 24 hours of contact, and it also provides residual repellency to extend protection. It is intended for outdoor use only, allowing homeowners to apply the granules as a band treatment around foundations, on lawns, or as a spot treatment on ant hills. The 3-pound shaker bag makes application convenient for medium-to-large yards, delivering a practical balance of coverage and ease of use.
Key features include immediate knockdown and ongoing deterrence, versatility in application around the home, and a formulation geared toward outdoor environments. Users should follow label directions to ensure proper dispersal and safety, especially around pets and children. While effective on multiple pests, Terro’s concentration and residue will vary by application rate and soil condition, so monitoring is advised to maintain lawn health and pest control.
Ortho Fire Ant Killer Broadcast Granules
This Ortho product is engineered for large-scale lawn protection. It targets fire ant mounds and the elusive queen to prevent regrowth, providing up to six months of protection with a single broadcast application. The granules are designed for ease of spreading across expansive lawns, helping reduce new mound formation and fly-in infestations. In practice, homeowners apply the granules to cover the entire lawn area, ensuring uniform distribution to inhibit fire ant activity across the property. The fast-acting formulation allows you to regain lawn enjoyment quickly while establishing a long-lasting barrier against new mounds.
Considerations include the product’s coverage area (suitable for larger lawns) and the need for reapplication after weather events or significant mowing. While long-lasting, consistent application according to the label is important for sustained control and to minimize environmental impact. This option is particularly appealing for those dealing with persistent fire ant activity across a broad outdoor space.
Ortho Fire Ant Killer Mound Treatment1

It is targeted for use on residential lawns, ornamentals, and flower gardens, where it can disrupt the colony and reduce ongoing activity. The product’s rapid action—often within 15 minutes—lets homeowners observe tangible results sooner, allowing for a more immediate return to outdoor activities. By addressing the mound at its source, this treatment aims to limit re-infestation and maintain healthier turf in treated areas.

Buying Guide: Key Factors To Consider When Selecting Lawn Ant Control
- Target species and scope: Identify whether you are dealing with mounds, foraging ants, or multiple pests. Some products focus on fire ants specifically, while others offer broader insect control for lawns and perimeters.
- Application size and coverage: For small yards, a 3–5 lb bag may suffice; larger lawns benefit from 10–13 lb options or broadcast granules that cover thousands of square feet.
- Speed of action vs. long-term protection: Quick mound treatments can provide fast relief, but longer-term granules may reduce re-infestation over weeks and months.
- Environmental safety and placement: Outdoor-use formulations minimize indoor exposure; consider pets and children when selecting products and follow label guidance for safe application.
- Residue and reapplication schedules: Check how long protection lasts and whether conditions (rain, irrigation) require reapplication to maintain effectiveness.
- Compatibility with lawn care: Some products mix with fertilizer applications or require separate timing; review compatibility with your seasonal lawn maintenance plan.
- Target pests beyond ants: If you have other lawn pests (spiders, grubs, ticks), consider broad-spectrum products or a combination approach to reduce the number of treatments.
