Ants are getting smarter these days.
I live in an area that is semi rural so in summer the ants come in esp at this time when it is hot.
Normally I put those ant square things down where they walk into the open section eat the bait and then die. It has always worked well in the past but this time they are walking around the square thing and not eating the bait. It is very frustrating.
Does anybody have any ant remedies??
Rubbing alcohol in a spray bottle is a contact kill that leaves no residue so it's safe to use indoors. 93% seems to work best. This also works well on other insects. No need to wipe up - just let it evaporate.
........
If you can find the nest, a mixture of liquid soap (1 pint soap to 1 gallon water) in a garden sprayer is also a contact kill. Stir the nest to expose the ants while spraying. Insects do not have lungs and absorb oxygen through their exoskeleton. By blocking their means of getting oxygen they die.

You can make your own bait with boric acid, something sweet like honey and water. Place in an empty water bottle and place near the nest or trail. This is similar to the Terro brand name bait. The boric acid dehydrates the ant and usually they take some back to the nest,..
Boric acid has nearly the same toxicity as table salt so it's safe - no chemical residue. Check online for the recipe. The boric acid is best dissolved in a microwave. Shake well when hot.

.About carpenter ants - the methods above will work. Follow the trail back to the nest. The ones forming the trail usually will not bite. Be ready to spray
before disturbing the nest and spray heavy on the first application. The ants in the nest
will bite when disturbed and it does hurt. After treating the nest any that still live will move remaining eggs to another location so it's good to hit them hard on the first application. They usually only come out at night - flashlight.
