Foods poisonous to ants often involve a sweet attractant mixed with a slow-acting poison like borax or boric acid, which they carry back to the colony, or substances that disrupt their digestive system, such as baking soda; strong scents like cinnamon, coffee grounds, and essential oils (peppermint, citrus) also deter them by interfering with their communication, though they aren't technically food.
Borax, Water, Sugar. Borax is a slow-acting poison for ants that will wreak havoc on their digestive system and cause them to die within a few days of ingestion. It is most effective if taken back to the colony, where (ideally) the queen eats it, too. Kristi: "We use borax, sugar, water, and a touch of peanut butter.
Borax and sugar will kill ants. If this is formed into a liquid with some added water, the worker ants will eat it (or is it drink it) directly. A video I watched suggested adding some bread to the liquid so the ants take some of this more solid food back to the colony for the larvae.
Use these seven household products to kill ants without pesticide.
#1 humans. Humans are the biggest threat to ants. Some communities in Southeast Asia and South America eat ants or their larvae. However, deforestation, pesticide use, urban expansion, and climate change pose significant threats to ant habitats, endangering many species.
You shouldn't squish ants indoors because it releases alarm pheromones that attract more ants to the spot, worsening the problem, and some ants release formic acid that smells like vinegar and can irritate skin. Crushing them doesn't eliminate the colony and can even disrupt their trails, causing them to spread out, so it's better to use baits or natural deterrents to handle the source, according to pest experts.
How to safely and effectively get rid of house ants
Store-bought pesticides generally kill ants within minutes. Dawn dish soap mixture eradicates ants in a slightly elongated timeframe, but terminates the ants' colony within two to three days.
Salt can kill ants via dehydration if they come into contact with it, which means ants are most likely to avoid salted areas, making salt more of a deterrent than a killer. 'Salt, especially table salt or rock salt, works by a process of osmosis.

Borax and Sugar
Borax is a natural mineral that can be used to kill ants. Mix borax with sugar to attract ants. The ants will return the mixture to their nest, killing the colony.
Baking soda is a safe DIY remedy for killing ants. Ants' foraging behavior makes them susceptible to consuming baking soda left out by homeowners. Baking soda must be ingested to potentially affect ants, requiring strategic placement where ants are active.
The strongest ant killers are typically professional-grade baits and sprays containing powerful active ingredients like Fipronil (e.g., in Anthem granules) or fast-acting gels (e.g., Synergy Pro, Advion, Optigard) that ants carry back to the colony for a complete nest kill, but for DIY, a homemade borax and sugar bait (Borax with honey/sugar syrup) is highly effective for sugar-loving ants, while diatomaceous earth (DE) offers a natural dehydrating option for a broader range.
This recruitment process allows thousands of ants to rapidly descend on tasty morsels, but it also makes them susceptible to toxic baits. These traps contain a delayed-action poison that kicks in after the ants have shared the food around the colony.
The Best Homemade Ant Killer (Kid & Pet Safe) This DIY Ant Killer is nontoxic, easy to make with 3 household ingredients, and works better than store- bought sprays! Ingredients 2 cups apple cider vinegar 2 Tablespoons dish liquid 2 Tablespoons baking soda Water as needed Instructions 1.

Ants hate strong, pungent smells that disrupt their scent trails and confuse their navigation, with some of the most effective being peppermint oil, vinegar, cinnamon, and citrus (lemon/orange). Other scents like tea tree oil, cedarwood, thyme, black pepper, and garlic also act as powerful deterrents, overwhelming their delicate olfactory senses.
