10 Best Indoor Insecticides 2026 in the United States

The TERRO T300-3SR Liquid Ant Killer is a popular choice for indoor ant control, especially effective against common household ants including those attracted to sweets. Its active ingredient, sodium tetraborate decahydrate (a form of borax), works by being carried back to the entire ant colony, which helps eliminate ants both visible and hidden. This bait uses a liquid formulation that ants find attractive, encouraging them to share it with the colony for a wider impact. One great benefit is its ease of use — simply place the bait stations around your home where ants are seen, like baseboards or counters, with no setup required. Users often notice fewer ants within a few days due to its fast-acting nature. In terms of safety, borax is generally considered low in toxicity to humans and pets when used as directed, but it’s still important to keep the bait out of reach of children and pets.

The product offers residual effects since the bait continues to attract and kill ants as long as it remains. However, it targets mainly ants and may not be effective against other indoor pests. If you're dealing with ant problems and want a convenient, non-spray option that works well indoors, this is a strong candidate. Just remember that it won’t stop new ants from entering, so combining it with good home cleanliness helps. It is a reliable and easy-to-use solution for ant infestations in homes.

Advion Cockroach Gel Bait is a strong choice for anyone dealing with cockroach infestations indoors or outdoors. Its active ingredient, 0.6% indoxacarb, is effective and non-repellent, meaning roaches don’t avoid it. This gel bait attracts roaches well and, after they consume it, they spread the poison to other roaches, helping to control infestations quickly—often within a day. It targets common species like German and American cockroaches, which makes it versatile for home use.

The bait comes in an easy-to-use syringe with a plunger and tips, allowing you to apply the gel neatly into cracks and crevices where roaches hide. The gel remains active for up to three years, so it provides long-lasting value. Its formulation is designed to minimize risk to people and pets, making it safer than some harsher insecticides.

This product is specifically for cockroaches and won’t affect other household pests. While it is safer, caution is still needed during application to avoid contact with skin or children’s reach. Some users may need to combine this with good sanitation and other pest management steps for best results. If you want a targeted, effective, and easy-to-use solution for cockroach control that lasts a long time and is safe around the home, Advion Cockroach Gel Bait is a reliable option.

The TERRO T300B Indoor Liquid Ant Killer is a popular choice for indoor ant control, featuring 12 bait stations designed for easy placement along baseboards, corners, and counters. One of the strengths is its fast-acting formula, which uses borax as the active ingredient to noticeably reduce ant activity within days. The ants carry the liquid bait back to their colony, ensuring widespread eradication beyond just the visible ants.

This makes it effective against a variety of common household ants, including acrobat, crazy, ghost, little black, odorous house, and pavement ants. Additionally, the product is ready to use with no setup required, enhancing its ease of use for homeowners seeking a convenient solution to ant infestations. Another benefit is its versatility in placement, allowing users to target ant hotspots throughout the home effectively.

However, it's important to note that while borax is less toxic compared to some other insecticides, it should still be handled with care, especially around children and pets. The residual effect is typically short-term, requiring ongoing monitoring and replacement of bait stations to maintain control.
