1. Natural Insecticide Spray Recipe with Soap
This powerful insecticide kills a lot of garden pests, chief among which are greenhouse slugs, plant fleas, and lice. Dissolve a spoonful of grated natural soap in 2.5 liters of water.

Cut an orange in two, scoop out the core, and put the peel on the ground, with the convex side up. The snails will give up the salad, to shelter under the new roof of the half orange. If you have frogs in your garden, you are lucky because slugs are their favorite food.

Some birds are amazing helpers in removing garden invaders and pests. Attract them into your garden, by luring them with a mixture of millet and black sunflower seeds. This mix will attract many insectivorous birds, such as goldcrests, European robins, and jays.
