The ants are most afraid of chili powder, garlic powder, which has a pungent smell. These methods can drive them away:

1. Baking soda

Baking soda is toxic to ants, but if you want to attract ants, you need to add appropriate sugar powder or a few drops of plant essential oil. After ants eat baking soda, their digestive ability will be disturbed, and finally the ants will hang up and sprinkle baking soda directly on it.

2. Lemon juice

Prepare enough lemon juice and sprinkle it in different parts of the house. Lemon contains the special smell of citrus fruit, and ants don't like this sour taste. The sour taste of lemon will mask the natural smell of ants. You can soak the lemon juice with cotton balls and then wipe it on windowsills, doorsills, cabinets or other places where ants haunt.

3. Food-grade diatom powder

Ants often visit around potted flowers or eat in the yard. At this time, you can sprinkle some diatom powder around, which is a natural ant repellent and completely nontoxic.

4. Orange peels

Except the peels of oranges, oranges, lemons and grapefruit, they contain high content of D- limonene, which can prevent ants from invading the yard and help drive away ants. You can completely dry these peels, then stir them into fine powder, and then sprinkle them on the ant infested areas.

5. Garlic

Garlic has the effect of eliminating all kinds of pests. Eating garlic every day is also beneficial to human health. Proper use can also help drive away all kinds of pests and ants who grow flowers. Ants can't stand the smell of garlic. Just put two peeled fresh garlic at the entrance and exit of ants.

6. Coffee grounds

Coffee grounds can be sprinkled around, or a circle of coffee grounds can be sprinkled around plants, which can effectively stop ants.

7. Clove contains eugenol, which becomes a substance that can directly kill ants after being made into essential oil. Some insecticides can also be made from clove, which is completely nontoxic. After the clove oil is sprinkled, even after drying, it will still leave a strong smell, which can prevent moths, flies, ants and other pests.

Extended information

Ant species and their control methods:

Ants are sensitive to temperature, and most of them are active in hot weather. They like sweet food, such as cakes, honey, maltose, brown sugar, eggs, fruit stones, skin, dead insects and so on. They can tell the way and act in a hurry. If individual worker ants die, their bodies will be transported back to the nest. But they are not hungry. Without food and water, half of them will die after four days and nights.

Experts suggest that domestic ants can be flooded with boiling water first, and then put into the ditch with washing powder to block it. It can also be used as a spray for killing cockroaches and mosquitoes. These drugs have the efficacy of killing little red ants. However, the little red ant is a semi-social insect, and the general spraying agent can only kill the worker ants who leave the nest. The queen ant and queen ant are still breeding wildly in the nest.

an ant queen can give birth to 611 small ants every second, so it is ideal to take collective action in the whole building to kill ants. The best way is to choose a drug bait with good palatability and no repellent effect on ants. After the worker ants move the bait back, they can poison the queen, queen and larvae in the nest and destroy the whole nest.

Use the characteristics of ants to eliminate them:

Ants are mostly found in the kitchen where there are oily foods, and this characteristic can be used to eliminate them. Before going to bed at night, move all the food where ants can't go, then put a piece of fat pork on the ground and prepare a bottle of boiling water. The next morning, the ants gathered on the fat fat and ate soundly. Don't scare the ants away, and immediately scald them to death with boiling water. This can be wiped out several times.

The harm of indoor ants to home is often overlooked. According to the investigation, indoor ants mainly include small yellow house ants, big head ants, Rocky Road social ants and smelly ants, which often nest in roadside, corner and wall cracks. The main ways of harm are stealing food, biting and spreading bacteria. According to its activity characteristics, some physical and chemical methods can be used to prevent it, such as blocking the activity route and blocking the nest. If conditions permit, biological hormones can also be used for prevention and treatment.

With the rapid development of our urban construction, the living environment of ants has changed greatly, and they gradually adapt to the urban environment with dense buildings and dense population, and often invade indoors to feed and nest. Because indoor ants can pollute food, destroy buildings, spread bacteria and bite people, they will do some harm to human life. In order to better prevent and control this harm, we must understand the species and habits of indoor ants, and then put forward some effective methods according to the specific situation.
