How to Rid Lawn of Ants

By Melody Dawn ; Updated September 21, 2017

Ants can be a nuisance. Ants will destroy your lawn and can get into your home. Some varieties of ants, such as the fire ant, can cause itching, swelling and even anaphylactic shock when they bite. It can be difficult getting rid of ants because there are thousands in a colony. The trick is to wipe out the colony and the queen in order to get rid of them. These types of treatments are usually in the form of baits. Ants are attracted to the bait, which contains poison. They carry the bait back to the colony and share it with others. You can get rid of the ants yourself with a few simple ingredients.

Mix together an equal mixture of boric acid and granulated sugar into your container. The container can be the lid off of plastic bowl or a milk cap. You can also use a Styrofoam cup and cut holes in the bottom sides for the ants to crawl through. Your ants will be attracted to the sugar but the boric acid will work as poison. Boric acid is not very toxic to humans but you should still keep it away from young children and pets. You also do not have to be exact in your measurements--just average a 50-50 mixture.

After you have mixed the acid and the sugar, add a little bit of water to make the mixture thick. It should not be too wet. You want the mixture to be very thick like cookie dough. You can achieve this by drizzling the water on top and not pouring it in. Store your excess solution in an airtight container. You can also dip cotton balls into water and place them into the solution before placing them into the container. This help to keep the solution from drying out.

Place the solution where your ants tend to travel. It's best to place it in an area that they are currently going through so they can find it. It may take a while for the ants to notice that it is there. Once they become interested in the solution they will begin to bring more ants. Don't kill any of the ants that are attracted to the solution. You want them to carry the acid back to the colony. You will want to have several traps if your ants are coming from different locations. Try using several baits instead of just one.

Wait a few days and check the sugar solution. Add to it so that they will continue coming back to it. It may take a few weeks for the whole colony to die out so be patient. The boric acid will eventually wipe out the entire colony of ants. This solution will work better and is cheaper than most commercial killers. The ants will stay interested in the sugar. They learn to avoid the commercial killers.

Switch from sugar to peanut butter if your ants do not seem to be interested in the solution. Some ants prefer a more fatty substance. You could also try using jelly or a Kool-Aid mixture instead of sugar water. You could also try mixing peanut butter and sugar with the boric acid to make sure you attract all of the ants.
