Just like bees, wasps are among the most ecologically important organisms for humanity: They pollinate our flowers and food crops. But beyond bees, wasps also regulate populations of crop pests such as caterpillars and whiteflies, contributing to global food security.
Wasps have a strong sense of smell, which they use to find food sources. You can take advantage of this trait by using scents they dislike, such as peppermint, lemongrass, clove, and geranium essential oils, vinegar, sliced cucumber, bay leaves, scented herbs, and geranium flowers.
Wasps and yellow jackets are beneficial insects. They feed their young on insects that would otherwise damage crops and ornamental plants in your garden. They can also feed on house fly and blow fly larva. Wasps and yellow jackets become aggressive when their nests are approached or disturbed.
You can befriend these beneficial wasps by providing nectar sources, mints and asters, in your landscape and thereby invite them to hang around and find some pestiferous white grubs to serve as food for their offspring.
What are they doing and why, and should I be worried? A: This is a European Hornet, a non-native social wasp that's been in the U.S. for well over a century. They are not aggressive towards people, but can be defensive around their nest or another perceived threat, so observe from a distance.
What to Do If a Wasp Lands on You

How Long Do Wasps Live? Wasp lifespans vary depending on the type of wasp. Social, worker wasps (females) have an average lifespan of 12-22 days. However, drones (males) live slightly longer, and queens can live up to one year (as they hibernate).
Can wasps sting you if they are dead? Yes — the venom sac at the end of a wasp sting keeps pulsing for a short period after a wasp dies, so if you come in contact with the sting you may still be injected with venom.
Golden paper wasps have demanding social lives. To keep track of who's who in a complex pecking order, they have to recognize and remember many individual faces. Now, an experiment suggests the brains of these wasps process faces all at once—similar to how human facial recognition works.
Wasps and yellow jackets will chase you when they feel their nests are in danger. They step up their defense and will do anything necessary to remove the threat from the vicinity of the nest or to escape – including stinging you.
Though both wasps and hornets are generally known to be more hostile than bees, bald-faced hornets are specifically more aggressive than wasps. These particular creatures will sting even if there isn't much of a threat posed.
In appearance, wasps are generally slender, while hornets are rounder and “fatter.” Hornets are usually yellow and black striped like a stereotypical bee, while wasps may be striped or solid red, black, or even blue. Nest types vary for both species. Wasps and hornets may each build “paper” nests of bits of wood.
For a quick method of telling whether a particular flying stinger is a wasp or a hornet, the first clue should be its size. If the insect is large - say, bigger than a fingernail - there's a good chance you're dealing with a hornet. If it's slightly smaller, with a longer middle section, chances are it may be a wasp.
A sting of a hornet hurts more than a sting of a bee or a wasp. This statement is probably true to anyone who has ever been stung by these insects. All the more surprising is the fact that the sting of a hornet is up to 50 times less toxic than that of a bee. Nevertheless, the sting of the hornet hurts more anyway.
Yellow jackets are actually the common name of a particular type of wasp. Wasps from the Vespula and Dolichovespula genera are called yellow jackets in the US. Yellow jacket species are smaller than other wasps but more aggressive. They're more likely to sting than other wasps, but their stings hurt less.
The sting of the paper wasp ranks at 3.0 on the Schmidt Pain Index. Paper wasp stings inflict a burning sensation that's been described as the same feeling as spilling acid on your skin. A paper wasp sting may also cause a bitter taste in your mouth.
Pain Level 4 is the highest level in the Schmidt sting pain index. Schmidt's original index rated only one such example, the sting of the bullet ant, as a 4. Schmidt has described the sting as "pure, intense, brilliant pain...
Bees will leave a barbed stinger behind. Wasps, on the other hand, have a smooth stinger they can use more than once.” Dr. Kuhn added that you're more likely to have a severe reaction from a bee sting because bees have a more complex venom.

First, the Gila monster has very sharp teeth, each about a quarter of an inch long. When the animal bites, it chomps down hard — and doesn't let go.
