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 Singapore 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 Singapore.

Prevent yourself from stinging bites

One way to protect yourself from stings and bites among the bees, wasps and hornets is to avoid provoking the nest and swarms. Do not flick and wave them away as they may perceive as threat or danger. In addition, avoid attempting to remove the nest without receiving proper training and licensing, and worse of all, not equipped with the right tool and safety outfits. When outdoors, you can also choose put on longer sleeves and pants to cover exposed skin from risk of bites. If you spot a nest or presence of these flying and stinging pest, do not panic and contact a pest control company right away.

Managing stings and bites wound

It is important to treat pest bites adequately and carefully. Most bites are generally harmless and may self-recover and symptoms are usually small and raised bumps that are itchy. However, some bites are more harmful where it contains toxins, spread diseases such as dengue fever or bites resulting in skin rash, infection or allergies. Remember to clean the wound area thoroughly, use an ice pack for swell reduction and seek medical attention if symptoms persist. Avoid scratching the bites as your fingers may habour bacteria, thus resulting in skin infection or inflammation.
