Well, right after I set-up our kids new swing-set, we notice a decently large ant nest right close to the swing-set. I want to get rid of them without any chemical treatment that would cause me to not allow my kids and pups out there. I read very hot water will do it, we tried that but the nest must be too deep. I've read of mixtures with Borax that are said to work, but haven't tried that yet...Thanks in advance for your suggestions.
Hot water rarely works on an established nest. The colony runs 2 to 3 feet deep and the water cools before it reaches the queen, so it rebuilds in days.
What works without chemicals near kids and pets:
Mix 1 part borax to 3 parts powdered sugar, or borax in sugar water on cotton balls. Workers carry it back and it kills the queen. Give it a full 1 to 2 weeks and keep the stations out of the kids' and pups' reach.
Food-grade diatomaceous earth. Dust it on the nest and trails. Mechanical, not chemical. Reapply after rain or watering since it only works dry.
Cut the food and moisture. Check for sprinkler overspray, clippings, or fallen fruit near the swing-set and clear it.
If the same nest keeps coming back or they move indoors, you may have a multi-colony species that home methods rarely clear. At my company,
My Termite Company in Los Angeles, that recurring-nest pattern is one of the most common reasons people finally call us in, since multi-colony species rarely respond to single-point treatment. For one nest by a swing-set though, the borax bait route should handle it.
