No need to buy pesticide when flowers and plants get bugs; a little something from home sprayed on them wipes them out completely

As temperatures rise, bugs start to multiply and increase. If you keep potted flowers and plants at home, small flying insects easily appear in the soil too, and some aphids and the like suck the sap from leaves and branches, affecting the plants' growth.But you don't want to spray pesticide - how do you get rid of these bugs? The methods are as follows:
1. If they are aphids, dilute a little potassium permanganate in a small bottle, dip a writing brush in it and brush the undersides of the leaves; the effect is good.
2. If the flowers and plants have whiteflies and bacteria, dilute one small spoon of laundry detergent in 3 litres of water.
Spray the leaves once every two days and they can be wiped out.
3. Take one cup of flour and half a cup of milk, then add water to dilute, and mix thoroughly and evenly. Filter once with a cloth strip, dilute with water and spray on the leaves; it can kill mites and insect eggs.
4. When it rains, snails in the flower pot will sneakily eat the tender leaves. Pour a small bowl of beer into the saucer under the flower pot, and the snails that pass through will drown.
5. Spray a mixture of garlic and pepper powder in the flower pot to prevent mice from invading.
6. If there are ants in the flower pot, soak cigarette butts in water for two days, then pour the cigarette-butt water into the flower pot, and the ants can be wiped out.
7. If there are small flying insects in the flower pot soil, you can fumigate with the mosquito coils you use at home against mosquitoes.
You can also spread a layer of fine sand on the surface of the flower pot, and the bugs will be greatly reduced.
8. If they are potted plants grown on the balcony, don't plant too many and place them so densely that there is no ventilation. Prune some overly dense branches in time, and often open the windows to keep things ventilated.
Keep the flower pot soil clean, with no debris, branches or leaves; do not use organic fertiliser that has not been fully decomposed; do not directly pour milk water or rice-washing water into the flowers and plants.
This way the bugs have nowhere to escape. The potted plants grow vigorously and look clean and fresh.
