Generally appear in the warmer months or when the crop is well advanced, and caterpillars want to eat, the sap from our marijuana plants.

Belonging to the family of Lepidoptera and known after itslepidoteros metamorphosis with the name of butterflies, caterpillars, there are many species and colors, are one of the most harmful invasions to the marijuana plant, but it is also true that they are easier to detect and therefore, is also easier to combat possible expansion in time.

Long and colorful segmented body, characterized by being able to easily blend in plants, allowing it survive the onslaught of birds who take them as authentic delicacies and all, regardless of the family to which they belong, have six legs “real” and 10 “false”, the position will vary from place according to species before which we find ourselves. This allows them to move relatively easily, although you can not say they are fast, but they have freedom to move and grip the plant.

The first thing you have to do is carefully observe the highest leaves in our plant or the highest buds because that’s where the butterflies lay their eggs. If you have not yet hatched eggs, you will usually find some small white or yellow spots can be round or elongated, depending on the type of butterfly that deposit their eggs at the plant.

If we are in flowering time, then we will have to take care of hojas-comidas-orugathe buds and begin with the top, to go down gradually to the trunk. If we find that there is any darker or rotted area for the invasion of eggs or caterpillars step already born, we cut and apply a product that repels or kills the caterpillar eggs. It is important to remove the damaged part of the plant, if you do not want that disease will spread throughout the plant and, then yes, we have nothing to do.

If the caterpillars are already born, you have to look the plant daily. It is recommended to do it at night, when greater moisture concentration is given and when these animals eat least, although during the day is when it will be easier to see them, because they will be eating so insatiable, as they have a hunger voracious.

One last tip: if you had a plague of caterpillars, when the harvest of the marijuana plant, we recommend that you hang upside down the plant, so that it loses its moisture, the caterpillar comes out, and become butterfly, outside the plant, and so never again lay eggs in it.
