What should I do if there are many small black bugs on the crabapple flowers?

1. Tobacco water

Prepare a cigarette, tobacco leaves, and a small basin of clean water. Then soak it in water, wait until the water in the basin turns yellow, then take out the cigarettes and tobacco leaves, pour the soaking water into a spray bottle, and spray it evenly on the place where the small insects are.

2. Soap liquid

Soak the soap used at home in hot water, mix the two in a ratio of 1:50, and allow the soap to be fully dissolved in the water. Soap is used because it can block the insects' respiratory organs. The insects will die after a period of time after spraying. It is especially effective against scale insects and aphids.

3. Garlic juice

After peeling the garlic, use a tool to crush it. You don’t need too much, just about 30g will be enough. Then add about 500g of water. After stirring it evenly, add the minced garlic and use the garlic water to spray on the leaves and flowers. If the effect is not good after one use, spray 3-4 times continuously.

4. Ginger juice

The methods of making ginger juice and garlic juice are the same. Both of them need to be crushed and put into water. Soak it for 12 hours. They also need to be filtered and sprayed on small insects. It can kill aphids, leaf miners and other insects.
