The appealing smell of Dawn dish soap tricks ants, drawing them to certain death. When mixed with water to make a soapy solution, Dawn dish soap breaks the ant trail scent, disrupting their movement and preventing an infestation build-up.
Soap. Common household substances like glass cleaner, liquid dish detergent, and hand soap can deter ants by removing the scented pheromone trail that leads ants to the food sources. Mix spray-on glass cleaner and liquid dish detergent, then spray areas where ants congregate.

Household items like citrus fruits, black pepper, peppermint oil, cayenne, thyme, and lavender can create natural ant repellents. Great for avoiding pesticides or conventional ant traps! Mixing parts of these substances with water in a bottle and spraying the solution around the house can keep ants at bay.
It turns out that soap and alcohol—the two main ingredients in Dawn Powerwash—are both great at killing insects. The soap clogs up insects' breathing tubes, essentially drowning them. Alcohol dries them out as well.
Dawn, a commonly used dish soap, contains surfactants that disrupt the exoskeleton of insects, leading to their dehydration and eventual death. This property makes it an effective bug repellent, as it can deter a wide range of insects, including flies, ants, and mosquitoes.
Another natural spider repellent you can make from household supplies is a mixture of water and liquid dish soap.
Natural deterrents.
If you know where ants are getting in, you can line these entryways with things that ants hate. Salt, baby powder, lemon juice, chalk, vinegar, bay leaves, cinnamon, or peppermint oil are a few items that you have around your home that will stop ants from coming inside.
You may love your morning coffee, but ants could do without it. Another natural way to deter ants, sprinkle coffee grounds outside and around your garden. The smell repels them and they'll be looking for a less caffeinated place to hang out.
Ants have a keen sense of smell and can detect sugar and sweets with ease. They are very attracted to chocolate, honey, and any other sugar-laden product. Other foods that are greasy or have complex carbohydrates will attract them as well. Even a few crumbs on the floor can have a room crawling with ants in no time.
If you leave toothpaste, soap scum, or hair care product remnants in the sink or on counters, ants might find a feast. They are particularly attracted to sweet, sticky substances, which is why spilled toothpaste or shampoo can be a major draw.
Most species of ants, including carpenter ants, dislike the strong scent of vinegar, which is why mixing it with water is enough to repel them. It's important to note that while the vinegar messes with the scent trail and prevents them from returning, the solution isn't enough to kill them.

It is also important to note that mothballs aren't effective at repelling most pests. A few mothballs might get rid of moths and their larvae, but they aren't going to repel bed bugs, rats, mice, spiders, or ants.
Perhaps one of the greatest natural enemies of ants is other species of ants. Some omnivore ants will attack and feed on other ant colonies. Additionally, certain smaller ants will connect tunnels from their colony to the tunnels of a colony of larger ants to steal food from the larger ants.
Mix equal parts baking soda and powdered sugar and place in a small lid or shallow container in the area where you're seeing ants. When ants nibble baking soda, it reacts with an acidic material in their stomachs and kills them.
Try pouring a line of cream of tartar, red chili powder, paprika, or dried peppermint at the place where you think ants might be entering the house; they won't cross it. You can also try washing countertops, cabinets, and floors with equal parts vinegar and water.
Hand sanitizer can be used in place of alcohol when mailing to preserve soft bodied arthropods such as aphids, spiders, insect larvae, (including caterpillars), and termites.
While the complete “recipe” is inaccessible for the masses, a Dawn spokeswoman has pointed the magic to uniquely powerful surfuctants—or, the chemical compounds that reduce the surface tension of a liquid when it's dissolved, aka the stuff that cuts the grease.
