In this article, we will explore some of the best ant killers on the market, focusing on their effectiveness, usability, safety, and duration. We’ll cover a variety of products that cater to different needs—whether you’re looking for indoor or outdoor use, pet-safe solutions, or long-lasting protection.
Best Overall: Ortho Home Defense Insect Killer

This versatile spray is effective against ants and a wide range of other pests, including spiders, cockroaches, fleas, and ticks. It’s ideal for use both indoors and outdoors, making it a comprehensive option for preventing and eliminating pest invasions.
What Stands Out:

- Ease of application: The included spray wand makes it easy to apply the insecticide in a controlled and continuous manner, ensuring even coverage.
Areas for Improvement:

Best Indoor: Terro Liquid Ant Baits
For indoor use, Terro T300B Liquid Ant Baits are an excellent option. These small, discreet bait stations attract ants with a sweet liquid that they carry back to their colonies, effectively eliminating the entire population.
What Stands Out:
- Colony elimination: Unlike sprays that only kill visible ants, Terro’s baits work by targeting the entire colony. Ants are attracted to the bait and take the poison back to their nests, where it kills the queen and other members of the colony.
- Ease of placement: The baits can be placed anywhere ants are spotted, such as along baseboards, near kitchen trash cans, or in room corners.
Areas for Improvement:
- Sticky liquid: The liquid inside the baits can occasionally leak, making it essential to place them carefully to avoid messes.
Product Details:
- Type: Liquid bait
- Targeted Pests: Ants
- Duration: 3 months
- Safe for Pets: No
The Terro Liquid Ant Baits are highly effective for indoor ant infestations, particularly when you can’t locate the source of the colony. Keep in mind that you’ll need to replace the baits regularly and ensure they are not placed near areas treated with insecticide sprays, which can deter ants from taking the bait.
Best Outdoor: Terro Outdoor Ant Killer
Terro Outdoor Ant Killer is designed to prevent ants and other pests from entering your home. Its granular formula works quickly, killing ants on contact and providing ongoing protection for up to two months.
What Stands Out:
- Easy application: The granules come in a resealable bag with a built-in handle for easy spreading. You simply shake the granules onto outdoor surfaces where ants are present, such as lawns, patios, and garden beds.
- Quick results: Ants and other pests begin to die within 24 hours of contact.
Areas for Improvement:
- Not pet-safe: The granules are not safe for pets and can be washed away by heavy rain, reducing their effectiveness.
Product Details:
- Type: Granules
- Targeted Pests: Ants, cockroaches, crickets, earwigs, millipedes, mites, and more
- Duration: 2 months

If you’re looking for an outdoor ant killer that’s easy to use and provides fast results, Terro Outdoor Ant Killer is a great option. Just be sure to apply it during dry weather and keep pets away from treated areas.

Additional Tips for Ant Prevention and Control
In addition to using the right products, it’s important to implement preventative measures to keep ants from returning to your home. Here are some tips:
- Seal entry points: Check for cracks, gaps, or holes around windows, doors, and foundations where ants can enter. Use caulk or weather stripping to seal these areas.
- Eliminate food sources: Ants are attracted to food and water, so keeping your kitchen clean and storing food in airtight containers can help reduce their attraction.
- Remove standing water: Ants, like most pests, are drawn to moisture. Fix leaky faucets and ensure there are no areas where water collects around your home.
- Clean up spills and crumbs immediately: Ants will quickly find even the smallest crumbs. Regular cleaning can prevent an infestation from starting.
- Trim back plants: If you have plants or trees close to your home, ants can use them as a bridge to get inside. Trimming these plants can help reduce access points.
Safety Considerations
When using any ant killer, always follow the manufacturer’s instructions to ensure safe and effective use. Here are some general safety tips:
- Keep children and pets away during application: Most insecticides are not safe for pets or children until they have dried or dispersed. Always allow the product to dry completely before allowing pets or children back into the treated area.
- Ventilate treated areas: Some sprays can have lingering fumes, so it’s best to ventilate the area after application.
- Store products safely: Always store pest control products in a secure place out of the reach of children and pets.
