Bees are flying insects closely related to wasps, hornet and ants, known for their role in pollination and, in the case of the best-known bee species, the European honey bee, for producing honey and beeswax. Strictly speaking, they are more of a envionmental friendly insect than a pest. However, their sting can be deadly for some species, therefore pest control for them are more for the safety of human beings especially children.
Hornet is the largest of the eusocial wasps, and are similar in appearance to their close relatives yellowjackets. Some species can reach up to 5.5 cm (2.2 in) in length. They are distinguished from other vespine wasps by the relatively large top margin of the head and by the rounded segment of the abdomen just behind the waist. Their stings are deadly as compared to bees.
