Ants will NOT cross over a chalk line. Put chalk wherever they seem to be coming from.
you have to find the place where they enter (window,
door...) and lay a thick line of baking POWDER as a
baking POWDER, NOT baking SODA!
it took two days, but now they are gone.
Did you try heaps of baby powder?
sprinkling flea powder on them and their pathways gets rid of them very nicely.
cinnamon works fine
hosing them down and sealing the space at the bottom of the door - even closing it off with rags can work. It took a few weeks, but the problem is final resolved.
I sprayed them with bleach.
since I started 'sponja' twice a week with those anti-jukim floor shampoo, (any brand) all my ants ran away.
Here is something interesting: it is said if you take a shovelful of ants from one hill or nest and put it in another ant hill then take a shovelful from that hill and put it where you took the first one the ants will then wage war on one another and do themselves in!
*Catnip, pennyroyal, peppermint, sage, and spearmint. Tansy which is often recommended as an ant repellant may only work on sugar type ants. These are the ones that you see on peonies and marching into the kitchen.
*Warning: You do not want to plant Tansy anywhere that livestock can feed on it as it is toxic to many animals. Do not let it go to seed either as it may germinate in livestock fields.*
leaves and flowers from sage, mints or tansy around the outside of your house or plants that are bothered by ants. These plants can also be used as a living barrier for ant control, bearing in mind that they are invasive in their growth habit and using cuttings from these plants as a barrier is more effective. We grow tansy in an out of the way place to harvest the cuttings.
* Vinegar sprays in and around the house foundation will repel ants.
Keep way from the soil and concrete. Lemon juice concentrate can
also be used: mix 50/50 with water and spray.
* Ants will not walk through a line of talcum powder or chalk dust.
Diatomaceous earth may also be used as a barrier in and out of the
* Using a silica areogel/pyrethrum spray applied to the base of
plants like eggplants and peppers can control fire ants from
girdling the stems and killing the plants. This is a good barrier
as it stays "put."
* Caulk all cracks and crevices in the building to deny them access.
Be sure to use high quality pure silicone caulking as these are
less likely to shrink or crack once applied.
* Distribute cucumber parings as a repellant. Cucumbers contain a
compound known as "trans-2-nonenal" that repels ants as well as
* Try sprinkling some of those instant grits around the nests. See
* For fire ants: Pour half a cup of Epsom salts into the nest and
all around it.
* On smaller plants a bit of petroleum jelly smeared around the base
will stop ants immediately.
* Pour apple cider vinegar down entrance holes to the nest.
* Using a sugar soaked sponge works well for light invasions of
ants. Use a large sponge with big holes in it. Soak it in a strong
solution of sugar water and place it where you want to catch the
ants. Rinse the sponge out every day in a container of soapy
water. Fix it up with the sugar water again and repeat as often as
* Dust such as Silica Aerogel can last a long time. Their mode of
action is to dehydrate the ants. They work slowly and are easy to
use in tight areas such as cracks or crevices.
* Make a strong hot water and hot pepper tea. Use the hottest
peppers you can find, finely chop them in a food processor, mix
with hot water. Pour directly on the nest.
* Douse the nests with boiling water several times. Cruel and can be
* Repeated flooding of the nest every few days using your garden
hose can often be enough to get them to relocate. You must be
persistent with this method.
* Make teas from tansy, catmint, peppermint or sage to use as
repellant sprays for ants.
*To make teas:* Take enough cuttings from these plants to tightly pack one 8 ounce cup. Bring 1 quart of water to a boil. Stir in the plants. Take off the heat and allow to cool. Strain this mixture, add 1 teaspoon of castille soap and use as a direct spray. You can also substitute 1 teaspoon of coconut oil soap in place of the castille.
