Wasps are aculeated hymenoptera, insects belonging to the Vespidae family. They are insects called eusocial, that is, colonies of insects that raise their offspring together by dividing the work. The most common are of the genus polistes, they live in small colonies, and their nests consist of a single honeycomb of cells without an envelope. Of this species, the dominulus is the Italian one, which due to its predilection for building their nests on constructions, artefacts and buildings, often makes cohabitation with humans impossible. The wasps lay their eggs directly on the bottom of the cells by attacking them with a sticky discharge. While in the first few days all the founding females of the nest can lay eggs, ten days after its creation only the dominant female can lay eggs. The wasps of the polistes family are commonly called paper wasps as they build their nests by mixing wood particles with saliva and their color resembles that of cardboard. Wasps are social insects, they live in colonies inside crawl spaces and some species in underground nests. Wasps have a sting that they use as a weapon to attack or defend themselves.Unlike bees, wasps can sting more than once and stay alive, making them more dangerous. Bees sting only if they cannot help it, they know that after having stung their sting it remains attached to the victim, detaching itself together with the abdomen resulting in the death of the bee.This is due to the conformation of the sting which in the bee is like a The harpoon, once penetrated, no longer comes out, while in the wasp it is like a needle. When wasps are disturbed, even if not intentionally, they attack by stinging to defend the colony. Their sting often causes severe irritation and in some cases even anaphylactic shock. The wasp nests are not always visible. Some colonies consist of 1000-2000 individuals. Some species of wasps can be particularly aggressive; if disturbed, they attack humans, and with the stings they can inoculate robust quantities of poison; especially when they swarm in swarms. If it happens to have to move near a nest or, unlucky, to harass them, the suggestion is to avoid lightning and sudden movements, in an attempt to free yourself from the attack.
