Doigthebountyeater I feel for you. It's been one of those year for us as well. Here's afew ideas you cab try. I like to try natural non toxic remedies so these might help:
Sounds crazy, but try vinegar! Fill a squirt bottle with plain old cheap white vinegar, and squirt it anyplace you've seen ants (kitchen counters, windowsills, etc) and let it dry. It's non-toxic, won't harm anything, and the smell will go away This worked for me!

Mop the floor with about half liter of water mixed with two to three drops of lavender essential oil. That will keep ants away.

1 Follow the trail of ants to determine where they come into the house.
2 Locate the holes. Fill the holes with soap or white glue; or Apply baby powder on the trail of ants. Ants that come in contact with the powder will die soon.
3 Apply more baby powder or red pepper to kill the remaining ants. After they are dead, sweep away the ants and excess powder or red pepper.

Try a natural repellent such as ground or powdered chili, or used coffee grounds. Citrus peel (ground) works well, too.
For a more permanent solution, find the ant mound, and destroy it using boiling water (to collapse tunnels) mixed with a teaspoon of salt (to confuse their sense of direction).
If you can't bear to kill them, at the start of summer leave a jar of honey up a tree in the garden. The ants will be happy to stay out of your kitchen.
Feed them corn meal. They eat it. They take it back to their nest and feast on it. They can't digest it and it kills them. Also, corn meal won't harm children or pets.
Wheat flour and dried rice (any kind) also work. Like corn meal, it expands in their stomach and explodes them, resulting in a death slightly less nasty than being boiled alive.
They also hate cinnamon but will eventually get used to it.
You can destroy their nests by taking a stake and stabbing it down into their nest. Wiggle it around until you have a fair sized crater. Fill the crater with baking soda about half way up and pour vinegar over it. It is all-natural and will totally destroy the nest. Don't worry about it leaving a crater in the ground, it mostly fills itself in and if it doesn't just kick some dirt over it, plant some grass over it, and you will never be able to tell the difference.
