Cellar without slugs
Pieces of plywood, linoleum or any other materials should be placed on the ground where they will be hidden from the dry daytime air. Then it remains only from time to time to collect them there. The cellar has completely different conditions. High air humidity and constant temperature (about 5 degrees) contribute to the activity of slugs throughout the year.
We have the most common slug mesh. These are small (about 2-4 cm in length) creatures with a reduced shell. They are hermaphrodites, that is, they have both male and female reproductive systems, fertilize each other, and each of them can lay up to 400 eggs. These are nocturnal creatures. In the morning they hide in humid places, and such "traps" of flat material are actually the only way to destroy them.
It's hard to talk about the size of traps: slugs can hide even under a brick left in the garden. The main function of such a trap is to maintain air humidity. Water pests are afraid, they need to breathe. Therefore, in the rain they climb on plants, tree trunks, walls.
In the cellar, if the whole floor is covered with dishes, boxes of vegetables and fruits, it is almost impossible to find them. They somehow know there when night falls. For a day they can hide at the bottom of the box with carrots, and under it, and in the corners, and along the walls in the ground, and with high humidity - even on the outer walls of the boxes or other containers.
In the 70-80s of the last century, the drug called Meafos against slugs was produced. He was gradually poured under the laid out "traps" - pieces of different flat materials. The slugs slid under them like bewitched, where they were collected. However, this drug is not on sale right now. A few years ago there was another anti-slug drug, Thunderstorm (not to be confused with Thunderstorm against rats and mice). It is also impossible to find on sale.
It remains only to raise all the boxes of vegetables above the floor by 20-25 cm and lay flat traps on the floor. After some time, the lower boxes will dry out, and the slugs will have no choice but to go down to the floor, into traps, from where they can be collected. To attract them even more, you can lay out under them slices of their favorite fruits and vegetables, necessarily cut. So slugs feel better.
Another feature of slugs: the small path of any of the cheapest mineral fertilizers or salt for them is an insurmountable obstacle. This can be used in the fall when they climb into the cellar through crevices or a stuffing box.
In nature, for the winter, slugs hide in crevices, in piles of weeds spread in the garden. Burning weeds, you can destroy them. For the winter, they do oviposition, laying 10-20 eggs each. This must be remembered, because even destroying them all, in May, children hatch from eggs laid in the fall. Therefore, in early April, the floor in the cellar should be sprinkled with chopped fertilizer, especially along the walls. Small slugs will not be able to crawl along such a mound and will die of starvation.
Oddly enough, people ate translucent eggs of slugs and grape snails (from 2 to 5 mm in size), salting like fish caviar. They did not differ from red and black caviar in taste and nutrition - only in color and price. Red caviar is harvested in tons during fish spawning, and oviposition of slugs had to be collected in 10-20 pieces in unknown places, which is why it cost ten times more.
It was a particularly exquisite and expensive delicacy: craftsmen grew slugs that laid eggs in designated areas and received considerable profits from this.
