how do I get rid of the dermal skin (earwigs) that gnaw at the newborn parsley?
earwigs, or lumps, are in fact not particularly harmful to cultivation, except in rare cases: they are usually omnivorous and feed on some new shoots, but also on aphids, ants, mealybugs, which wander around our plants ornamental. More than anything else they are annoying, because they are gregarious and tend to appear in mass; especially when they colonize a small space, such as a terrace or a balcony, their presence becomes annoying, because during the day they hide in the dark and damp areas, and when these are represented by the sponge near the bathtub, it is clear that the result becomes very annoying. Having said that, I understand that if due to the humidity (which these insects adore) the earwigs arrived en masse in your garden, it is at least annoying to find them everywhere; even more so, since there are so many, even a single taste at the head of the new basil sprouts, to make a considerable damage. Generally these insects are not particularly affected by the more widespread insecticides, which leave them completely undisturbed; you usually opt for home remedies, such as attracting them to a place, and then moving them away. One usually proceeds by placing crumpled newspapers in a shaded area of the garden, or even under an overturned vase; within a few days a large number of scissors will have chosen this shelter as a dwelling, and therefore they will be able to take and move, perhaps in the garden, away from the vegetable garden, or burn (depending on how many they are, from the extent of the damage that they dealt). I repeat, however, that these are useful insects altogether, and therefore, rather than chasing them all away, it is better to remove them, or rather, make them desist from their intent to feed on your parsley. Usually insecticidal baits, those against snails, those against ants, and even small traps for cockroaches, tend to remove the earwigs: hardly any specimens killed by poison are found, so I think it is not because they feed themselves directly bait; but perhaps they "taste" the insects that have fed on the bait, and finding them unpleasant decide to move to another place with more interesting preys. Also the insecticide for terrestrial insects usually works, this is also in the form of granular bait, and usually spreads on the ground while working it; now that you've already sown you can try to spread some granules on the ground between the already sprouted seedlings.
