Nine of the ten roses died, 1 second homemade insecticide, red spider aphids all swept away!

Aphids, red spiders

Aphids

Aphids, also known as dense insects and greasy insects, are the most troublesome pests for us to grow vegetables and flowers. They multiply quickly and do great damage. When the temperature is above 12 degrees Celsius, they begin to reproduce rapidly.

Red spider

Red spiders, also known as spider mites, can reproduce a generation every week, and the more balcony the rose is planted, the easier it is to breed red spiders!

How to eradicate aphids and red spiders?

I believe that many flower friends have tried to buy medicine to kill insects, and the results are not ideal. In fact, we have plenty of "insecticides" that can be used at home, fast DIY, do not ask for help!

1. Rub it off with your bare hands

Flower friends of domestic roses must observe in time. Once bugs are found, they should be rubbed off with bare hands or toilet paper immediately.

If you have more thorns in the rose, be sure to wear thick gloves.

2. Release the seven-star ladybug

Seven-star lady beetles are the natural enemies of aphids. Catch a few seven-star ladybugs in the suburbs or botanical gardens and eat them automatically on the rose, leaving no aphids!

Seven-star lady beetles love to eat aphids and have no sense of rose, so they can not only eat up the insects, but also do no harm to our flowers!

3. Spray with a kettle

Spray the aphids with a high-pressure kettle and spray the bugs away. It's really a resentment.

4. Chili water

The dried chili shell is slightly chopped and soaked overnight. The next morning, pour some water on the rose to make it full, and then spray the worms with pepper water that filters out the chili shell.

Chili water will stimulate and kill aphids and red spiders, and it is also irritating to the rose, so let the rose drink full water before using, pay attention to spray on the insect, do not sprinkle it into the basin soil.

5. Washing powder water

200ml water + 15ml washing powder + 3ml cooking oil, stir well, pour into a small spray can, insecticidal bar drip ~

Water the rose before spraying, in case the rose drinks the detergent water. The purpose of adding oil is to attach the medicine to the leaves and suffocate the insects.

6. Soapy water

Soap: water = 1: 300, mix according to this ratio, wipe rose leaves with small toothbrush or cotton pad dipped in soapy water

Soapy water is very alkaline, can also have the role of disinfection and sterilization, can accurately kill bugs!

7. Cut tobacco water

Take out a cut tobacco from a cigarette, soak it in 200ml water, soak it overnight and then wipe the wormed leaves.

Aphids and red spiders can't stand the smell of tobacco and will soon be smoked to death.

8. Garlic water

Peel off a head of garlic, smash it with a knife, then add 300ml water, soak for 1-2 days, and the super-exciting insecticide will be ready.

The retted garlic water is put into a small spray can and sprayed at the insects is simply powerful!

9. Washing essence

Detergent: water = 1 Rd 500, stir well and stand still until the foam has dissipated.

You can put it in a spray can and spray worms, or you can wipe the leaves with a wet towel. Try not to sprinkle it into the flowerpot so as not to hurt the rose.

10. Mosquito incense

A mosquito-repellent incense plate hanging near the rose bushes can kill larger aphids and red spiders.

Relatively small rose has insects, after lighting mosquito-repellent incense, you can cover it with a large carton, so that the concentration of mosquito-repellent incense is higher and the insecticidal effect is better, but pay attention to fire prevention!
