Garlic water

Usually the most common garlic contains allicin with strong bactericidal power. It is definitely a small expert in killing insects and sterilization! Flower friends can mix some garlic water when watering the flowers and kill scale insects, aphids and nematodes every minute to make the flowers grow up healthily

1. Mash garlic cloves

First peel off the garlic skin, and then mash it into garlic paste. The more broken it is, the better it can be, so as to give better play to the insecticidal and sterilization effect of allicin

2. Add clean water and let stand for 24 hours

Put the garlic paste into a plastic bottle, and then pour water into the garlic paste. The ratio of garlic paste to water is 1:20. Screw on the bottle cap and put it in the shade for 24 hours

3. Garlic water spray leaves, insects die

After soaking in garlic water for 24 hours, put the upper liquid in the bottle into the watering can, spray it at the position where there are insects, and then spray it on both sides of the leaves. Spray it once a day for 3-5 times continuously, and the insects will be finished, which is not only environmentally friendly but also easy

Ailanthus altissima leaf

The special odor of Toona sinensis can effectively kill insects and bacteria, and its leaves also contain flavonoids and other effective components to kill insects.

Washing powder water

Washing powder is really a necessary thing for every household. Washing powder water can effectively kill red spiders, scale insects, whiteflies, aphids, etc. This is because washing powder water can dissolve the wax on the body surface of pests, and form a film on the body surface of pests to isolate the air and suffocate pests

1. Dilute the washing powder 800-1000 times

Choose neutral detergent to kill insects. Don't use too alkaline detergent to prevent burning the tender leaves of flowers. Take a spoonful of washing powder, pour 800-1000 times of water, stir evenly, and make it completely melt

2. Spray on insects

Put the fully melted detergent water into the watering can, spray it on the leaves and branches of aphids and red spiders, try not to spray it on the basin soil, use it once every three days, and the insects will die after using it for 3-4 times in a row

3. You can also use a brush

You can also find a soft brush, dip it in detergent water and gently brush the place where there are insects, which can better prevent the detergent from flowing into the soil

4. Spray the branches and leaves with clean water in time

Check the leaves carefully the next day after spraying. If you find that the insects are gone, spray the branches and leaves with clean water to prevent the branches and leaves from being corroded by washing powder

Chili water

Many flower friends say that after raising flowers, xiaoheifei keeps growing at home. Try chili water quickly. It contains irritant capsaicin. No matter how many xiaoheifei can be killed, it is absolutely non-toxic and harmless, making the flowers grow

1. The hotter the pepper, the better the insecticidal effect

Flower friends should pay attention to that when choosing pepper, the hotter the better. If you use vegetable pepper that is not spicy enough, it will be far from achieving the effect. For example, very spicy Chaotian pepper, dry pepper or fresh pepper can be used

2. Chop pepper and boil water

Chop the pepper with a knife. If it is fresh pepper, be careful not to splash the juice into your eyes. You'd better wear gloves to prevent it from getting hot

3. Filter pepper water and spray it on pests

Filter out the pepper residue with a filter screen, dilute the pepper water by 50 times, put it into a watering can and spray it towards the position where there is xiaoheifei. After spraying, xiaoheifei is all dead and the body falls to the ground
