Step 1: Keep them outside
Easier said than done, right? First, get a good outdoor bug spray to spray around your house once a month. Raid Max Bug Barrier works wonders. Don’t use it indoors, as it can be harmful to children and pets. Next, seal off all cracks in windows and doors using caulk. Caulking can be found at any home improvement or hardware store, such as Home Depot or Lowe's, for less than $3.
Step 2: Fully seal all spices
Finding ants in your flour when you’re about to bake is almost as bad as burning a meal you’ve just spent hours prepping. Avoid getting them in your flour by putting all spices in plastic containers that snap shut. Ensure they stay out by trying this home remedy — place a bay leaf inside the container (bypass a bay leaf flavor in your spices by taping it to the top of the inside of the lid). Bay leaves can also be used in cabinets to keep ants out.
Step 3: Use adhesive tape
Adhesive tape can be used for specific problem areas, such as a cookie jar, to guarantee ants can’t get in. Simply wrap the tape around the base of the item, sticky side up.
Step 4: Keep the kitchen clean
This may seem obvious, but keeping the kitchen as sanitized as possible is an effective way to prevent ants from coming in and taking over. Every day, wipe down the countertops with a simple solution of warm water and dishwashing liquid detergent. This can also be used on cabinets and inside the refrigerator. Make sure foods are always put away and sealed tightly. Keep the floors clean by sweeping and mopping with a sanitizing solution such as Swiffer WetJet weekly.
Step 5: Try home remedies
Finally, there are a few interesting home remedies for keeping ants at bay. Outline the outside of your house with chalk. Ants are repelled by the calcium carbonate in chalk and don't like to cross that line. Make an orange puree — orange peels blended with warm water — and pour over anthills. This will send them away instantly and they won’t be returning anytime soon. Sprinkle cayenne pepper alongside baseboards and the backs of cabinets to send ants running. Ants are normally looking for sugar, so finding cayenne pepper instead tells them there is no sugar anywhere ahead.
