I use to take Ajax camping for ants so I would imagine it works around the house, too.

May your blade be ever sharp, and may you have little cause to draw it
May your roof tree shelter friends and family
May your table always groan under feast foods and flowing mead
And may your hearth always hear tales of good deeds.

Indoor and Outdoor Ant Control
Supplies: Diatomaceous earth
Instructions: Dust food-grade diatomaceous earth along the ant’s pathways.
Note: The white powder will cut through their exoskeleton and they will dehydrate and die.

Indoor and Outdoor Ant Control Supplies:
1 1/2 cup Cream of Wheat
Instructions: Place a dish of Cream of Wheat where the ants can access it.
Note: After they eat it, the cereal expands and the ants will explode.

• 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 in just a couple of minutes. It worked for me!

• I have a suggestion for the ant problem; plain old cinnamon. I put in or at the site of the ant invasion, they back off quick!

• Black pepper is a nonlethal, poison free, cheap, and safe way to get rid of ants – sprinkle the black pepper where you see them congregating and watch ‘them scatter. Follow them to where they’re exiting – which is the same spot they’re entering in at – and sprinkle the pepper at that spot to keep them from coming back in. It’s safe to use in your cabinets, on windowsills, near your pets and kids, around food, etc.

• I have a book with several tips for the use of apple cider vinegar. One of them is getting rid of ants. Make a mixture of 50/50 water and vinegar and pour it into a spray bottle. Spray the surface with the solution several times a day. Ants guide themselves with their scent. Vinegar has a natural chemical that alters ants’ scent and which ants avoid.

• My husband was in conversation recently with a gentleman in the pest control business. This man preferred to use environmentally safe methods to control pests. His recommendation for ants was: equal parts Windex and Ivory Soap. Simply mix, and spray problem areas.

• Most ant poisons have a sweetness to them that attracts most but not all ants. Some ants are attracted to grease. Observe your ants and see what they like, maybe you need a different bait. Also, though this is sometimes difficult, see if you can trace them back to where they are getting in, because caulking is usually the best solution, as it prevents recurrence.

Organic Suggestions from the Organic Gardner:
Outdoor Ant Control
Supplies: 1 to 2 gallons water
Stove or barbecue grill
Instructions: Heat water to 160 to 170 degrees. Quietly sneak up to the mounds of ants and pour the boiling water down the hole.
Note: I normally try to do this between 11am and 2 pm.

Indoor Ant Control
Supplies: 1 tbsp. boric acid
1 tbsp. mint jelly or peanut butter
1 cracker
Small cardboard box
Instructions: Mix the boric acid and mint jelly; spread mixture on a cracker. Punch pinholes in a cardboard box; place cracker inside. Place box in an area where ants cause problems, but away from children and pets.
Note: The mint jelly or peanut butter lures the ants in and the boric acid kills them.
