Wasps are considered a family or a household name under which a yellow jacket is classified. Invasive species of wasps have the potential to become real threats. In this sense, the yellow jacket wasp represents a high risk for the Chilean social and ecological balance. What are the basic aspects of this species and its incidence as a pest? If you are only concerned about their extermination, then visit everpest.com/blogs/blog/how-to-get-rid-of-wasps for details on how to deal with them safely.
Yellow Jacket And Wasp: Characteristics And Behavior
The yellow jacket wasp (scientific name Vespula germanica) is an insect native to northern Europe. It was introduced in Chile in 1968 through hidden specimens in the containers of ships that arrived at the port of Valparaíso.
It has a series of distinctive physical and ethnological attributes that allow its identification, among them:
- Complexion: Its size ranges between 1 and 2 centimeters. It has black antennae and a body with yellow spots, short legs, a bulging abdomen, and a low waist.
- Habitat: It prefers cold forests and mountain ranges, which explains its settlement in central Chile. Likewise, they usually live in underground nests with a diameter of 90 cm and 14 honeycombs or cells.
- Predator: Its diet is made up of carbohydrates and proteins, such as honey, nectar, fruits, other insects, and carrion.
- Aggressiveness: Attacks people if they handle meat, fish, or pick fruit outdoors. The sting is a clear difference between the bee and the yellow jacket: while the former loses its sting, the latter can sting several times.
- Reproduction: Queen wasps begin the cycle when they are fertilized in the fall. They survive the winter by hibernating underground or being protected in trees, cellars, and caves. Finally, they emerge in spring to form a new colony with a capacity of 20,000 workers and 175-200 queens.
In his time of awakening, the government authorities carry out the yellow jacket control. Thanks to this, for example, in 2020 a reduction of two million insects was achieved in the Los Ríos Region.
Yellow Jacket Wasp Hazards
The presence of a yellow jacket carries a constant danger to life at home, especially in health matters.
The venom contains a high concentration of antigens that activate the antibodies of the immune system. This can cause common allergic reactions such as pain, fever, redness, swelling, or even anaphylactic shock, which can lead to kidney, heart, and liver failure.
Economic And Ecological Risks
The Ministry of the Environment estimates that the yellow jacket has caused annual losses of US$21,532,771 and losses of US$496,995,010 are projected over the next twenty years.
The affected productive sectors demonstrate their interest in consolidating integrated pest management on the yellow jacket, to avoid risks in sectors such as:
- Viticulture: Yellowjackets crush berries as they feed, causing fruit loss and sour rot.
- Beekeeping: Prey on bees, deeply impacting the honey market. In addition, the disappearance of native wild bees implies a break in the fertilization cycles of flowers and fruit trees.
- Floriculture And Fruit Growing: Damages the ripening fruits of apple trees, pear trees, figs, and quince, among others.
- Livestock: A difference between bees and yellow jackets is that the latter devour meat from exposed wounds of any type of livestock or poultry, unlike bees that do not eat meat directly, but only microbes, in addition to nectar, pollen, and honey.
- Tourism And Recreation: The influx of visitors to national reserves decreases. This is because they harass people who bring barbecue meat. Thus, the absence of a yellow jacket control leads to lower ticket sales during its busiest months.

- Boiling Water – the nest must be filled with 10–20 liters of boiling water, and then its entrance should be closed with a stone or any other object. This method is no less effective than burning out while being almost completely safe for the environment;
- Contact Insecticides – the hole and the soil are flooded with specialized poisonous compounds that have a toxic effect. Almost any specialized means can serve as such, however, the most commonly used drugs for this are Karbofos, Aktara, Solfisan, Kukaracha, Troapsil, and Tsimbush;
- Poisoned Baits – near the nest, you should install feeders with pickled food. To do this, the contact insecticide should be supplemented with boric acid salts (according to the instructions), and then treat sweet fruits (melon, watermelon, etc.) with the resulting liquid. Also, on its basis, you can prepare a syrup, which should be placed in a small saucer. The method is quite effective but may require at least 2 weeks.
