1, baking soda: Just sprinkle baking soda directly where ants are infested. After ants eat baking soda, their digestive ability will be disturbed, which will eventually lead to the death of ants.
2, lemon juice: you can soak lemon juice with cotton balls, and then wipe it on the windowsill, threshold, cupboard or other places where ants are infested.
3. Mix a bowl of water with about 15 ml of soap, add baking soda appropriately, and then sprinkle it directly in the area where ants are distributed, or spray it with a watering can.
4. Orange skin: Except the skin of oranges, oranges, lemons and grapefruit, it can drive away ants. Their peels contain high content of D- limonene, which can prevent ants from invading the yard and help drive away ants. These peels can be completely dried, then stirred into fine powder and scattered in places where ants are infested.
Materials and Methods: According to the investigation and statistics of common pests in families, there are mainly four kinds of ants, namely, small yellow house ant, big head ant, Rockwell social ant and smelly ant. Through the analysis of the characteristics of these four ants, although they are far less harmful than cockroaches and flies, they are still hidden dangers at home. Therefore, according to their characteristics of digging holes and leaving a special chemical smell on the activity path, the following methods can be used to remove them: ○○○○○○○○○○○○○○○○○○○○○○○967 ○ Flooding: that is, watering floods the ant nest, which is more suitable for ants to nest in flowerpots. ○ Chemical control: Dust: Inhaled dust such as silicic acid (silica) powder is usually used to make ants die of lack of water; ○ fenvalerate silicate powder mixture: This method is an improvement of the previous method, which can shorten the killing time, but fenvalerate itself or dust should be avoided from being inhaled indoors; Spraying chemicals around the nest mouth and on the ant path can directly contact and kill ants. This method is easy to cause environmental pollution and resistance. The commonly used chemicals are: more than 90% trichlorfon stock solution is sprayed with 500- 1000 times solution; 50% DDVP EC or 80% DDVP EC 1000- 1500 times, 2000-3000 times; 0. 1% pyrethroid kerosene solvent spray, etc. These methods are effective and quick, but they are not thorough, difficult to eradicate, and easy to cause environmental pollution and drug resistance. Poison bait: Poison bait is a mixture of chemicals and food bait that ants like to eat. According to the mating behavior of ants, a worker ant can bring poison bait into the nest as long as he doesn't die in a short time. Generally, the death time is within seven days, but the pupae of ants may survive without eating, which leads to incomplete extermination of ants. Juvenile hormone analogue bait: that is, juvenile hormone analogues, such as floxuridine and methoxyprene, are mixed in the bait, and the hormone concentration is generally 0.6% ~ 1.5% of the weight of the bait. At present, it is under development. There are ants in the closet. You can put some vegetables such as parsley and celery to drive away the ants. Put some walnut leaves, tobacco and peppers in places where ants often haunt, which can drive away ants.
