Eliminate the Food Supply

If you have a dirty house, the ants will multiply and before you know it, you’ll have a full blown invasion on your hands.  The answer is simple, of course. Take away their food supply and you will have less ants.crumbs on a plate attract ants

Consider investing in air tight containers. I use Oxo containers and love them.

They seal easily and my pantry doesn’t have any evidence of ants in it since I started using them.Air tight containers keep food away from ants

Moisture is a Problem, too!Moisture attacts ants too

The reason you find ants in the bathroom is that they are always on the look for water. Once they find a good source of it, they will return and stay nearby.  Don’t let moisture to sit on counters and other sources.

Wipe up spills quickly.

Seal off Entry Pointscaulk leaks in windows

Ants are tiny and their entry point into a house can be small, too.  If you see a large number of ants, it is pretty easy to find out how they are getting indoors.

Apply caulk to crevices around doors and windows that the ants are using to get inside. Inspect both the inside and outside of your property.

The best way to get rid of ants in your home is to keep them out of it in the first place by having well sealed windows and doors.

Make Ant Baits

There are lots of natural ant killer remedies that will kill and repel ants if you do discover them. Borax is a commonly used ingredient to kill ants.

If you don’t mind chemicals, retail products such as Terro ant killer works well to kill ants. Home made ant baits

I recently tested five homemade Borax ant killers against the retail product Terro.  It may surprise you to see which one was the winner.

Salt is your Friend but not the Ant’s!

Salt has a drying out effect on ants, and this is especially true if they take it back to their nest.  

You can spread salt near windows, and doors and along the walls of your home. While the salt won’t kill the ants, they will avoid it.Ants will avoid salt.

You can also try making a saline solution to trick ants into thinking it is a water source.  Just mix a cup of water with a tablespoon of salt.

If the ants do drink it, they will be come thirstier, drink more and will eventually die.

Get Rid of the NestAnt hill

To keep ants out of the house, try to find their nest. It takes time and patience to find the ant nest.

Contrary to photos of large ant hills, most ants in your back yard are not as evident. You may need to search for it.Ants love sweet items

Try leaving something sweet outside and watching for ants to find it.  Once you see a bunch of them on it, try to follow them back to the nest. This may take a while, but is worth it.

Once you find it, you can pour boiling water, boric acid or other ant killers on the entire nest.

Cleanliness is the Key

Keeping a clean house is one of the most important things you can do to keep ants out of the house. Sweep the floor after you cook and after meals.

Make sure kitchen counters and sinks are kept free of food particles. Ants are attracted even to small amounts of food, particularly if it is sweet.

Wiping counters with a solution of vinegar and water is a short term solution. Ants hate it and will avoid counters but only for a few days.

Cleaning bucket

Don’t leave dirty dishes in the sink.  Take the time to wipe down bottles when cooking – putting a jar of honey back into the pantry with drips on the side is just asking for an ant invasion!  

All foods not kept in the fridge should be put into air tight containers if possible.Dirty dishes in a sinkWhile it is important for your whole house to be clean, the kitchen is the one that should get the most attention.

Since this is where food is prepared, it stands to reason that it will be the most attractive room to ants.

Empty Trash Bins

Empty your trash bins daily, and locate them away from the house if possible. These bins attract ants like nothing else and having them right beside the kitchen door is as good as saying “come on right in” to the ant colony.

Call in Professionals

Sometimes, the best thing to do is to call in professionals. If you have a huge ant invasion, it can be hard to control them yourself.

My brother and I have been having an ant problem for the past couple of weeks and we can't seem to get rid of them. It was really helpful when you mentioned that airtight containers are a good way to eliminate an ant's food supply. In addition to getting better containers, it would probably be a good idea for us to find a pest control agency that can spray entrance points around our home.

Great tip about finding the ant nests outside of your house. That way you can know where the sources are to get rid of them. I'll have to hire an exterminator to set down some poison.

My family will be staying at my brother's beach house for a vacation and I wanted to make sure we stay pest-free. It really helped when you emphasized that wiping up liquid spills quickly can prevent bathroom ant buildups because we will definitely be using a lot of water-related products and appliances during the summertime. I'll be sure to remember the rest of your tips while searching for a pest control service to have an initial removal before we settle in. Thank you!

Tried baking soda and powdered sugar to I left the back door inside for 3 days . Wipe the countertops and in front of cabinets with vinegar and Dawn. Don’t want to use chemicals inside. Waiting for the rain to stop and I’ll Put Borax and peanut butter outside. Maybe you have some other suggestions. Would be appreciated. Thank you

I have listed all of the remedies that I know of. Your options are limited if you don't use chemicals. I find that vinegar and water works well, but needs to be reapplied.
