Question: parasites

For some time now, in my small garden, small, thin, almost red pink worms about two centimeters long nest beneath the surface of the soil and near the root in the center of the heads of salad. in a few days the head withers and the plant dies. What can I do to eradicate this parasite and what product can I use? thanks

Answer: parasites

Dear Carlo,
the behavior of devouring the roots of the salad could be that of the nocturnal larvae, try to find some pictures on the internet to see if they are really those. These larvae feed on roots and foliage throughout their life, and can cause serious damage to the garden if the population is high. They are fought using specific granular baits, easily available in any nursery.
