The bites that really hurt (and some that kill)
When talking about bites, pain is one of the first factors considered, but it is not the only one. Some bites and stings cause only temporary discomfort, but others can trigger severe allergic reactions (anaphylaxis), dangerous infections, or the transmission of life-threatening diseases.
Bullet Ant: Pain like a bullet
His name is not free. The bullet ant's bite is famous for causing pain comparable to the impact of a bullet.This insect, found in tropical areas of South and Central America, is not lethal but is extremely painful.

Wasps, bees and their side effects
Bees are not aggressive by nature, but their stings can be lethal to people with allergies.In Spain, between four and five deaths are recorded each year from severe allergic reactions (anaphylaxis) following bee or wasp stings. Furthermore, Bees release alarm pheromones when they sting, which attract others to attack.It is estimated that more than 500 bites would be necessary for a healthy person to have a high risk of death.
The Asian hornet (Vespa velutina), an invasive species in Europe, is especially feared for its aggressiveness and the size of its colonies. Its bite is extremely painful and, in some cases, has led to hospitalizations due to severe reactions.
Bites and stings that transmit diseases
Beyond the pain, many bites pose a health risk due to the diseases they can transmit.Below, we review some of the most relevant ones.

Mosquitoes are responsible for more human deaths than any other animal. Its transmissions include diseases such as malaria, dengue, Zika, chikungunya and West Nile virus.Its bite usually causes a welt that itches for days, but the real danger lies in its ability to act as a vector for pathogens.
Ticks: small but dangerous
Ticks attach themselves to the skin to feed on blood, and can transmit diseases such as Lyme disease or typhus.Their bites go unnoticed at first, but once they swell, they become easily visible. They can cause fever, extreme fatigue, and, if left untreated, can affect various organs.
