Bee, Wasp and Hornet Species
There may be hundreds of species of bees, wasps, and hornets found around the world. Only a few of these are seen as real pests here in Malaysia and some of them do not sting. Some species, like the Honey Bee, are actually a valuable part of our ecosystem. Understanding their habits, lifecycle and appearance can help to identify the best form of wasp control for your home or business.
See our list below of common species in Hong Kong.
