To get rid of aphids you can use a lot of chemicals, but why not try an eco-friendly solution? It’s very simply and cheap because you don’t have to mix any ingredients. Just collect some small and cute insects to do this job!
Lady bugs are small insects, and their favorite food is aphids. You can collect them from parks or garden in a box of matches, and set them free in the area with aphids.
Or you can attract them in your garden by planting dill, fennel, marigolds, calendula, yarrow and so on. You can grow these plants near the crops attacked by aphids.
