Why do wasps become defensive?
Introduction to Aggressive Wasps
Wasps are often perceived as a threat by humans, mainly because of their potentially aggressive behaviour. Several factors influence the aggressiveness of wasps, ranging from colony protection to eating habits.
To understand why wasps can become aggressive, it is important to examine their behaviour, habitat, and the circumstances that drive them to attack. In France, the most common species include wasps (Vespula vulgaris) and Germanic wasps (Vespula germanica).
Why are the Wasps aggressive?
Protection of the Queen and Colony
The Queen's protection is paramount for a colony of wasps. Attacks often occur when a wasp perceives a threat to its nest or queen. A sudden movement or an approach too close to the nest — often located under the roofs or in crevices — can be seen as aggression.
Famine Periods
During the warm months, especially in late summer, wasps become more aggressive in search of food. At this time, natural sources become scarce, causing wasps to venture to places of human consumption in search of leftovers of food or sweet drinks.
Species of Wasps and Their Behaviour
Among the different species of wasps, some are notoriously more aggressive. For example, the Germanic wasp is well known for its defensive nature. Compare this to bees, which often sting once before dying, while wasps can sting several times without dying.
Understanding and Anticipating the Behavior of Wasps
Anticipating wasps behaviour can minimize negative interactions. Key elements to consider include:
- Avoid sudden movements near wasps nests.
- Be vigilant during meals outside during the summer.
- Use natural repellents where wasps have been observed.
What to do in the case of Wasp's Aggression?
In the event of a wasp attack, the following are some crucial steps to follow:
- Stay away from the nest: Don't shake your arms and don't scream.
- Protect your face: It is often the main target during an attack.
- If you're stooped, stay calm: Remove the darter quickly and apply a cold compress.
For more extreme situations or for people allergic to injections, it is recommended that you immediately consult a doctor or call an emergency.
Protection and prevention measures
The best way to manage wasps is to prevent their installation on your property. Here are some practical methods:
- Seal any openings in walls and roofs.
- Eliminate potential sources of food.
- Set up traps away from areas of human activity.
Call for a Professional
In the event that wasps have established a large or dangerous colony, it is advisable to employ a professional insect control. These experts have the tools and expertise to deal effectively with the problem safely.
Q & A on the Aggression of the Wasps
How can we react to an aggressive wasp?
It is recommended to remain calm, avoid sudden movements, and slowly move away from the area where the wasp is located.
Why were wasps stinging several times?
Unlike bees, wasps do not lose their dart after stinging and are therefore able to sting several times.
Comparison of Wasps Species
| Species | Behaviour | Aggressiveness |
|---|---|---|
| Common Wasp | Defensive near the nest | Moderate |
| German Wasp | Very defensive, aggressive | High |
| Polish Wasp | Less aggressive | Low |
Summary and advice
Managing aggressive wasps requires not only adequate behaviour but also preventive measures to secure its environment. It is always recommended to use professionals for long-term and safe solutions.
