Appearance & Features:
Wasps are easily identified by their black and yellow head and stripped abdomen. Worker wasps are generally between 10mm to 20mm in length.
Wasps build nests which can house thousands in the colony making them very social insects. The nests can be found in many locations including underground, in trees and bushes, eaves and attics, garden sheds etc. Every autumn the colonies die out leaving the queen - during this time they can become very aggressive. The primary food source for wasps is sweets and protiens and commonly invade outdoor activities.
Wasp Sting Treatment:
Wasps can be very aggressive and can apply repeated stings. Treatment is easy in mild cases by washing the sting with soapy water and then applying some ice to the stings. It's also recommended to take an antihistamine (even if you're not allergic to wasp stings).
Allergic reactions to wasp stings can range from mild to severe symptoms which can result in hospitalisation and death. Milder reactions may include redness around the sting, swelling, itching and some pain. On the other end of the scale however, things can become more serious with fainting, sweating, headache, stomach cramps and vomiting, tight chest and choking sensation and swelling of the throat and in extreme cases death as a result of anaphylactic shock.
Wasp Nest Prevention:
During the winter months wasps go into hibernation and usually only the queen will survive to lay her eggs. During the cold months other wasps seek shelter in warm dry locations such as attics and under floor boards.
To kill off a wasp colony a special powder is either injected into the nest, or left at the entrance, so that as the wasps come and go they pick it up on their feet. This powder kills the wasps, and as they all have to come back to or leave the nest, it ensures that it gets all of them. This is the quickest, safest and most effective wasp removal technique.
