You can almost hear them marching in now — under the doors, through cracks in the wall, even under window frames.

We all know ants are pesky little nuisances.

No matter where you live in the United States, you likely have to deal with ant assaults on your home, especially during the spring and summer months.

So what can you do to keep your house ant-free this year?

The answers aren’t as difficult as you may believe.

Pest-control experts offer these six easy tips to keep ants out of your home:

• Many ants enter the home through tiny gaps between the wall and utility lines, around windows, and other small holes and cracks around the home.

A little caulk around these areas will make a big difference.

• Keep vegetation about one foot away from the home, and avoid placing mulch close to the structure.

Ants climb bushes and trees and will make their way from the outside into your home, and mulch is an attractive nesting spot for ants.

• Fix water leaks and insulate cold pipes or appliances on which condensation develops.

The most important thing in an ant’s life is water, and they will readily enter your home to get it.

• Don’t overwater houseplants. If the tray at the bottom of the plant fills up, empty it out right away.

• Leave pet food out only at feeding time, and store the food in plastic airtight containers.

• Forget sprays. It’s easier and more productive to strategically place baits around the house so that ants will take the poison from the baits back to their colonies.

When you use a spray, you only kill the ants you see.
