Besides the bees, discover 5 insects best to have nearby.

The ladybug

Surely one of the most famous auxiliaries. The ladybug is known to eat aphids! Decorated with one or more peas, each ladybug eats up to 50 aphids per day. Enough to quickly get rid of these pests of roses and tomatoes. To attract them to the garden, let certain wild herbs grow, such as nettles, borage and knapweed. They are also attracted to nasturtiums, roses and fennel.

You can also buy ladybug larvae, to place in the appropriate location.

The hoverfly

The hoverfly is a fly that pretends to be a wasp, using yellow and black stripes. The wasp has two pairs of wings while the hoverfly has only one. In addition, the wasp has a body that refines itself between the torax and the abdomen, which a hoverfly does not. Either way, this imitator comes in handy. Even more voracious than ladybugs, the hoverfly eats up to 300 aphids in a day. In addition, this pollinator flies from flowers to flowers and thus allows the reproduction of many plant species. Remember, nearly 90% of flowering plants depend, at least in part, on pollination by insects. By the way, 35% of what we eat comes from plant species that reproduce thanks to insects. To attract it, choose flowering plants from late winter until fall. Don't hesitate to leave decomposing organic waste (like compost), hoverflies feed on it.


Earwig or ear clip? Behind this national debate which makes people react as much as the pain au chocolat and the chocolatine, hides an ally of the gardener. This little insect is recognizable thanks to the clip located at the bottom of its abdomen. The earwig feeds on larvae, caterpillars, aphids and psyllids, useful for the vegetable garden! However, he is criticized forenjoy ripe fruit, like peaches, apricots and plums. A common technique is to place an upturned terracotta pot filled with straw on the peach tree. Then simply move it to the tree affected by the psyllid, such as pear, fig or olive.

The earthworm

With its underground movements, the earthworm actively participates in the quality of the earth. Indeed, it mixes the different layers of the soil, bringing nutrients in depth. Each earthworm consumes about 30 times its volume in soil every day! Their droppings then constitute a rich, loose and airy soil. The roots are more easily established there, the soil is richer, more stable and less sensitive to the phenomenon of erosion. This true artisan of the earth guarantees a rich and loose soil, ideal for cultivation.

It is also used in vermicompost, to recycle its organic waste into an excellent soil.

The wasps

They have a bad reputation, while most are peaceful. It's the polist wasps that come to dinner in the summer and get us in trouble. However, their larvae are heavy consumers of small caterpillars, which the adults bring back to them. If they establish their nest at the back of the garden, leave it there!

Being part of the social wasps, this family cleans your vegetable garden of many pests. If they have enough to eat in the garden, they won't bother you at the table. Other garden helpers: solitary wasps, feed on aphids and are quite harmless.
