Wasp Pest Control and Treatment for Wasps Stings

Wasp Stings

Wasps sting to defend themselves or their colony. Stinging involves the injection of protein venom that causes pain and other reactions.

Wasps can sting more than once because they are able to pull out their stinger without injury to themselves. If you are stung by a wasp, the stinger is not left in your skin.

Very rarely, a person may suffer a life-threatening, systemic allergic reaction to a wasp sting, which can cause anaphylactic shock fainting, difficulty breathing, swelling, and blockage in the throat within minutes of being stung.

These systemic symptoms are cause for immediate medical attention. People with known systemic allergic reactions to bee or wasp stings should consult with their physician.

The venoms of bees and wasps are different, so having a severe reaction to a wasp sting does not mean a person will have the same reaction to a bee sting.

Control of Nests

The first step in wasp control is to correctly identify the insect and locate its nesting site. An experienced pest control service may provide wasp treatment, or you can use the following information to attempt to control them yourself.


One of the best times of the day to control wasp nests is at night, when they are less active. At temperatures below 5° C, wasps have difficulty flying.

Never seal a wasp nest until you are sure there are no surviving wasps inside. If a nest is not discovered until autumn, control may be unnecessary as imminent freezing temperatures will kill the colony.

Exposed wasp nests:
Wasp nests that are visible but are not near your home or areas of human activity do not need to be treated. If they are not disturbed, the wasps won’t bother you.

Nests that are near human activity can pose a potential problem. If there is a concern about stings, you should eradicate the nest.

Mechanical control without insecticides is possible for small, exposed nests. At night, cover the nest with a large, heavy, plastic bag and seal it shut.

Cut the nest from the tree and freeze it or let the bag sit in the sun, which will kill the wasps inside in a day or two. Use caution: there is more risk involved in this procedure than in spraying the nest.

Ground wasp nests
European wasp control is needed the wasps become a problem and are found either nesting in the ground in roof voids, entry to the home etc you could first try pouring a soap and water solution into the entrance.

Many types of soap will work, including detergent and laundry soap.  A word of warning the European wasp is known for it’s sting and they sting more than once and don’t die afterwards.

If you have an allergy to stings this encounter with wasp could prove life threatening, and this job should be left to the professionals who have all the right equipment not to be stung!
If that doesn’t work, apply an insecticide into the nest opening. Be sure you use a product that is cleared for use in lawns or soil. Dusts are more effective than liquid insecticides because liquids do not always reach the nest. After you are sure all the wasps have been exterminated, cover the nest entrance with soil.

When treating ground-dwelling wasp nests, use the following insecticides: Permethrin e.g. Coopex as a dust.

Concealed wasp nests:
The most challenging nests to control are those that are concealed in voids behind walls or in roof voids. Often, the only evidence of the nest is wasps flying back and forth through a crack or hole in the home.

In this circumstance to be on the safe side you will need to call in a professional firm.

How to Manage Wasp Control Safely

WaspsThe European wasp produces stings that are very painful. If you notice their hives, stay at a safe distance and out of their flight path if possible. Their stinger is different from a bees, in that is does not have a barb which stays in the skin. Wasp nests are leathery and are usually found in gardens.

Wasp Sting Treatment

If you are stung by a wasp, the treatment is as set out below:

Try applying an ice pack every hour. This will reduce the swelling. Also wash the area with an antiseptic such as Dettol as per the label in a 1:20 dilution with water. Take a pain killer to stop the pain that will usually accompany the sting. Take an antihistamine if there is persistent itching, but don’t scratch.

The swelling should subside within a few hours, though the pain & redness may take awhile.

If you develop an allergic reaction to stings, the above first aid may not help you much.

In such a scenario, always consult a doctor. Medication will always depend upon how severe is the allergic reaction.

Severe allergic reactions can sometimes cause anaphylaxis AKA anaphylactic shock which can result in a low blood pressure, compromised respiratory functions due to a bronchospasm, or even a circulatory collapse which may lead to breathing problems.

Severe allergic reactions occur when the sting poison enters into the blood stream. Treatments often include the injection of an antihistamine.

Placement of a tube into your trachea to help breathing, intravenous fluids, and of course hospitalization and close monitoring.
