Find a large basin to fill with water, then squat in the flowerpot with ants. The water surface is slightly higher than the surface of the basin. Soak for about 20 minutes, and take out the flowerpot, so that all the ants in the flowerpot are killed! But this method has the risk of retting roots. It is not recommended to use wet flowers.
In summer, ants are particularly fond of recruiting. There are chicken bones left at home. You can put 1-2 chicken bones at a place about 2cm away from the flower pot. After 2-3 hours, ants will all run out to carry food. At this time, kill ants directly with insecticides!
Generally 10 days to trap and kill once, you can kill the ants in the flowerpot! Don't think it's cruel. Ants have amazing fecundity. If you don't kill them, the whole flowerpot will be full of ants for a while, and then it's too late to regret!
Chop up the chili, garlic, onion, etc. at home, soak them for 24 hours, and then pull out the residue. The remaining mixed water can be put in the watering can, spray directly to the place where there are ants in the plant, and also can drive all the ants away!
If there are snails in the flowerpot, you can get some eggshells, clean them and dry them in the sun, then crush them into small pieces with your hands, or step on them directly.
Sprinkle the eggshell directly on the surface of the pot, or around the pot for a week. The edge of the egg shell has sharp edges. When the snail comes over, the sharp edges will cut its abdomen, so the snail generally dare not climb to the flowerpot.
The flower friends who have lime at home can sprinkle a little lime on the basin surface. It's better to sprinkle along the basin edge, away from the root system, and of course, it's better to sprinkle a circle around the flowerpot.
Lime is strongly alkaline. Snails come out in the evening to look for food. When they want to climb to the flowerpot and gnaw at the leaves of flowers and plants, they will die of dehydration when they encounter lime. In this way, the flowerpot won't attract ants any more!
The flower friends who grow purple perilla at home can also try to crush several pieces of purple perilla leaves, and then lay a thin layer on the basin surface. Because snails hate the taste of purple perilla, they dare not come back in the flower pot where they scatter purple perilla!
If there is centipede in the flower pot, you can try to make some tobacco, soak it in water for more than 24 hours, then filter out the tobacco, and fill the remaining tobacco water directly!
Although there is a certain toxicity in the tobacco soaking water, this kind of toxicity is only for centipede, which is harmless to plants. You can use it at ease!
Sprinkle some tea bran powder on the basin surface, and then water it. Let the tea bran powder gradually soak into the flowerpot with the water. Because the tea saponin in the tea bran powder can kill the centipede larvae and drive away the adult centipedes.
Tea bran powder is alkaline, for those sour flowers, try to use less. Moreover, the tea bran powder is also a natural organic fertilizer, which can supplement nutrients for flowers and make them grow more prosperous!
Use electric mosquito repellent incense at home. Don't throw the replaced mosquito repellent incense. Crush it directly and throw it on the surface of the flowerpot. It can easily kill centipede. Because of the residual toxin in the burned mosquito repellent incense, it is very effective for centipede and other insects!
