Snails and slugs

Outdoor cultivations do not require the use of as many tools as indoor cultivations, on the other hand the quantity of parasites that we have the possibility of finding increases.

Snails and slugs can cause serious damage to crops even if they move slowly and are easily identifiable, following this guide we will teach you how to fight and protect yourself from this serious threat.

The body of snails and slugs is slimy and soft, they range in size from 1 to 9 cm. Snails in particular have a shell that is the "home" of the mollusk itself.

The slowness of these little animals is proverbial and they leave a trail of clearly visible, shiny and transparent mucus. Snails usually come out of their shells in spring because they don't like the winter climate, however it is often possible to spot them after a rain because they love humid environments. Snails and slugs have an interesting peculiarity: they are hermaphrodites, even if they cannot self-fertilize and therefore always need another individual for reproduction. The opalescent colored eggs laid have a hatching period of approximately 30 days.

To recognize their presence, pay attention to these things:

  • Bites on leaves, with spider web shape. You can also find them on the roots of plants.
  • Mucus, the trail of mucus is a sure sign of the presence of snails or slugs.
  • Observe the plants at night with a flashlight, preferably with a green light so as not to disturb the plants' sleep.
