Getting rid of ants is never a simple proposition, despite their simple nature. Luckily for you, you're trying to get rid of sugar ants, and they are probably the most simple-minded ant species. What do they eat? They eat sugar, sweets, and other scraps of food. This is why we call them sugar ants. Of course, the term sugar ant is actually a misnomer. The real Sugar Ant is a native of the Australian continent, and exclusive to that part of the world; you won't find them here. The ants you're probably having trouble with are Pavement Ants and Pharaoh Ants, and for the purposes of maintaining simplicity in this article, we will refer to both Pharaoh and Pavement ants as sugar ants. After all, both ants are controlled and killed the same way.
So, are you ready to get rid of sugar ants? Good. Let us begin with controlling a sugar ant infestation and then move on to killing sugar ants.
Sugar Ant Control
Sugar ant control is very much a matter of daily routine during the months when sugar ants are a problem (March through September), particularly in the kitchen. Below is a list of things you can do to control sugar ants and prevent a sugar ant infestation in your home.
If you want to control sugar ants, you need to keep your kitchen sink clean and dry. Sugar ants love a dirty sink and the water you leave them to help wash down the leftovers. Make sure to rinse out any dishes you're going to leave in the sink over night. And when you do clean the dishes, make sure you rinse and wipe down the entire sink to make certain you haven't left residual sweets, food, or moisture behind. If you're really picky about cleaning, you might even want to try pouring a little bleach down the drain to make sure the smell of rotting food doesn't attract more ants to your kitchen. Dish drains should also be emptied and wiped down befor the end of the day.
Wipe down kitchen counter tops with bleach each night to get rid of sugar ants. Sugar ants love a dirty countertop almost as much as they love a dirty sink. I can't count the number of times I've spilled a few crystals of sugar (for my morning coffee) from the sugar cup on the counter, only to find I've fed an entire colony of ants the next morning. Wiping your countertops with bleach will not only help sanitize your kitchen, but bleach breaks down the pheromones that ants use to follow each other to sources of food.
Sweep and mop your kitchen floor with bleach every night during the summer to control sugar ants. I worked in a large kitchen long enough to know that it is in your best interest to sweep and mop your kitchen floor after every meal, or at least once in the evening to make sure any pheromone trails a scout sugar ant has made aren't left for other sugar ants to follow. Scraps of food and residual sugars are easily swept away with a bucket of warm water and bleach.
Vacuum the floors of spaces where food is regularly consumed to avoid inviting sugar ants into your home. It might seem like common sense to vacuum your dining and living rooms to prevent sugar ants from feasting on the leftovers of your most recent meal, but people just don't get it. So, I thought I'd mention the fact that sugar ants don't just eat sugar and sweets, they will eat crumbs of bread, certain types of vegetables and meat as well, even the remains of other pests that could be hiding in your carpet. Make sure you get all this stuff off your carpet if you want to get rid of sugar ants.
Use strong garbage bags and take the trash out regularly to avoid sugar ant infestations. It's often the case that a garbage bag gets punctured, dripping fruit juice or some other kind of liquid onto the floor while you're taking out the trash. Make sure to use strong garbage bags, even garbage bags that use Arm & Hammer baking soda to deodorize themselves, if you want to prevent a sugar ant infestation. It should go without saying that taking out the trash on regular basis will reduce the chances of sugar ants finding their way into your kitchen.
How to Kill Sugar Ants: Ant Baits
The most common ant baits used to get rid of sugar ants are called sweet baits, and the most common ingredient found in sweet ant baits is boric acid, or Borax. Most household ants (pharaoh ants, pavement ants, and little black ants included) are prone to the poison known as Borax. Borax is a mineral mined in the deserts of California, refined and dissolved into all manners of ant bait systems. It is generally non-toxic to humans, though I wouldn't recommend inhaling or ingesting large amounts of it. It is a slow-acting poison, which means that when the ants eat the bait (usually corn syrup), the poison doesn't kill the ants right away. The ants take some of the sweet bait back to the colony with them and dispense the poison meal to other ants. This is how colonies of ants are exterminated, and sugar ants are the easiest ants to kill because they're small, voracious scavengers. If you want to get rid of sugar ants or kill a sugar ant colony quickly, I prefer Terro brand sugar ant baits.
