Wasps, often perceived as pests, can spoil outdoor meals and, above all, cause painful stings. To avoid having to resort to insecticides, many people are turning to making and installing wasp traps.
Understanding Wasp Behavior
Before designing an effective trap, it is important to understand wasp habits. They are attracted to sweet foods, proteins, and fermented odors.
Wasp Life Cycle and Diet
Wasps have a well-defined life cycle, going through the stages of egg, larva, pupa, and adult. They feed mainly on nectar and ripe fruits, but also on meat, insects, and carrion.
Wasp Attraction Factors
- Smells: Wasps are attracted to sweet smells, fermented smells, and proteins. The smell of fermenting fruit is particularly attractive to Vespa crabro wasps, a common species in Europe.
- Colors: They are attracted to bright colors, especially yellow and red.
- Period of activity: Wasps are most active during the summer months, from June to September.
Types of Wasp Traps
There are two types of wasp traps: commercial traps and DIY traps.
Commercial Wasp Traps
Commercial traps are generally made from durable plastic and are available in a variety of shapes and sizes. They offer the advantage of being ready to use, but can be expensive.
A popular commercial trap is the plastic wasp trap with a liquid bait. It is often sold with a sweet bait and is designed to attract wasps into a container where they are trapped. The "X" brand wasp trap is an example of a popular product on the market.
DIY Wasp Traps
DIY traps are an economical and ecological alternative to commercial traps. They are generally made from recycled materials, such as plastic bottles or barrels.
Types of DIY Wasp Traps
Bottle Traps
Bottle traps are simple to make and require little material. Simply cut off the top of a plastic bottle, invert the cut part, and place it in the bottom of the bottle. You can then add bait and hang the bottle.
Barrel Traps
Barrel traps are larger than bottle traps and can capture a larger number of wasps. They are usually made from plastic or metal barrels. You can add bait and an entry system to trap the wasps.
Bait Traps
Bait traps use bait to attract wasps into a cage. The cage can be made of wire or plastic.
Dripping Traps
Dripping traps use a liquid bait that drips into a container. The wasps are attracted to the bait and fall into the container where they are trapped.
Light Traps
Light traps attract wasps using UV light. The wasps are attracted to the light and find themselves trapped in a container. A commercial light trap can capture up to 5000 wasps per night.
Wasp Baits: The Key to Success
The effectiveness of a wasp trap largely depends on the bait used. The bait must be attractive enough to attract wasps, but also toxic enough to kill them.
Sugar-Based Baits
- Fruit syrup: a mixture of fruit syrup and water, with the addition of a little vinegar to accentuate the fermented odor.
- Fruit juice: a mixture of fruit juice and water, with the addition of vinegar or yeast to increase attractiveness.
- Sweet mixtures: a mixture of sugar, honey and water.
- Fermented sugary water: a mixture of water, sugar, and yeast.
Protein-Based Baits
- Meat: a piece of raw or cooked meat.
- Fish: a piece of raw or cooked fish.
- Eggs: boiled or raw eggs.
- Cheese: a piece of strong cheese, such as Roquefort.
Fermented Fruit-Based Baits
- Wine: red or white wine.
- Beer: dark or blond beer.
- Fermented fruit juices: fermented fruit juice, such as grape or apple juice.
The choice of bait depends on the preference of the wasps and the region. In general, sugar-based baits are more effective at attracting wasps that feed on nectar and fruit. Protein-based baits are more effective at attracting wasps that feed on meat and insects. Fermented baits are particularly effective at attracting wasps that feed on fermented fruits.
Techniques for Installing and Using Wasp Traps
The installation and use of traps are essential steps to ensure their effectiveness. It is important to choose the right location and follow the assembly steps correctly.
Choosing the Location for the Trap
It is important to place the wasp trap in an area where wasps frequently pass. Areas with high wasp traffic are generally located near food sources, such as garbage cans, barbecues, or ripe fruit. It is also important to choose a location sheltered from wind and rain.
Techniques for Installing Wasp Traps
Wasp traps can be installed in different ways: suspended, fixed, or strategically placed. The installation technique depends on the type of trap and the location chosen.
Tips for Optimal Use
- Regular checking: It is important to check the traps regularly to ensure they are working properly and that the bait is not exhausted.
- Emptying and cleaning: It is important to empty the traps and clean them regularly to prevent wasps from escaping or the trap from becoming a breeding ground for bacteria. It is advisable to do this every 2-3 days.
- Bait renewal: It is important to renew the bait regularly to maintain the attractiveness of the trap.
Safety
It is important to handle traps with care and keep them out of reach of children and pets. It is also important not to touch trapped wasps. It is advisable to wear gloves and protective clothing when handling traps and baits.
Alternatives to Wasp Traps
If you do not want to use wasp traps, there are alternatives to control these unwanted insects.
Preventive Methods
- Eliminating sources of attraction: It is important to eliminate sources of attraction for wasps, such as ripe fruits, poorly closed garbage cans, or unprotected sugary drinks. A simple net over the garbage cans can prevent wasps from accessing the waste.
- Maintenance of premises: It is important to keep the premises clean and well maintained to prevent wasps from settling. Regular mowing of the lawn and pruning of trees and shrubs can help prevent the presence of wasps.
- Protection of food: It is important to protect food by covering it or placing it in airtight containers. Especially during outdoor meals, it is advisable to cover food dishes to avoid attracting wasps.
Use of Natural Repellents
- Aromatic plants: Some aromatic plants, such as citronella, lavender, and rosemary, can repel wasps. It is possible to plant these plants around your terrace or garden.
- Essential oils: Essential oils of citronella, lavender, and peppermint can also be used to repel wasps. Simply dilute a few drops of essential oil in water and spray the mixture around the areas to be protected.
Making and installing effective wasp traps are simple and effective methods to fight against these unwanted insects. By following the advice in this article, you can get rid of wasps and enjoy your summer in peace.
