The common bee or wasp is not generally considered dangerous if you are talking about the insect by itself; its only when a hive or nest is present that they pose a danger to anyone that might accidentally disturb them.
Wasps have a small head, with medium sized eyes and medium length antennae. The body is slender, with a narrow waist. They have two pairs of brown-tinted wings, with the forewings larger. The abdomen has some yellow bands on black. Adult wasps generally feed on nectar so they pollinate flowers as well. The ovipositors in most wasps are modified into stingers. They will sting if disturbed.
Wasp larvae are carnivorous. They feed on other insects and spiders. The adult female provide food for them by capturing prey or by laying the egg on or near the food source. Female wasps spend most of their time in finding food and making nest for their young.
Most wasp species are solitary, but some of them, such as the paper wasps, form colonies.
It is strongly recommended that if you have a wasp nest at your property that you don’t try and get rid of it yourself. These insects can be unpredictable and in some extreme cases attacks have lead to death
