Invasion of aphids, roses heavily infested

I am quite sure that the problem did not exist last week, but yesterday I noticed that the leaves of the roses looked partly completely eaten up and then I noticed this disgusting green clump of aphids on the blossom, and on practically every one. And we have many roses.

The ones [VOR der Haustür] are also infested.

I went to the garden center immediately today, and we were given Cefaclor. I will mix it as soon as the sun is gone, and then it will start. The seller said I have to hit every leaf. That is hardly possible with the dense vegetation, there are thousands of leaves after all?

Here the lice have also hit hard these days
Spray vigorously with water instead of watering from below
Pour black tea over
Peel garlic cloves and stick them two-thirds into the soil near the roots

The slugs annoy me and that even though the ducks were often here in spring

I also spray off vigorously with the hose, that removes most of it. The rest is not harmful, and I don’t want to poison my beneficial insects.

With garlic and black tea, I had good experiences last year

We ordered and released ladybug larvae last year.

And how did it help?
