A wasp will not fly properly at night if the temperature is below 50 degrees Fahrenheit.
Workers perform their jobs constantly during the day and night, but they rest in the hours in the early morning hours before sunrise. They stir again in the morning, after the sun rises. Most active in summer, these workers die off as cold weather approaches.

The best time to treat is at night, when the hornets and wasps are less aggressive. Hornets nests have a single opening, usually toward the bottom, where the wasps enter and exit. … Standing directly below a nest increases one’s risk of being stung. Spraying into wasp nests should ALWAYS be done at night.
Long Live the Queen
In the vast majority of cases, mated queens are the only wasps and hornets to survive the winter. They do so by hibernating under bark, in a rock crevice or in a burrow.
Are They Attracted to Lights? Worker hornets are active at night. They are attracted to lights and they may startle homeowners by flying into windows where lights are visible.
When the weather begins to turn warmer, in late March or April, she will emerge and go about the task of rebuilding a colony. The queen will build a paper nest and lay eggs, which turn into worker hornets.
Hornets eat leaves and tree sap but are also accomplished predators, feeding on flies, bees, and other insects.
Unlike bees and wasps, hornets fly both day and night, preying on moths and insects. They are attracted to light and, if we leave the bedroom window open on warm autumn evenings, they tumble inside.
To get rid of Hornets, we recommend applying Stryker Wasp and Hornet killer directly to Hornet’s nests to knock down the nest and kill any live Hornets inside the nest. You can then apply Sylo Insecticide and D-fense Dust around your home and yard to discourage re-nesting.
If you look at queen wasp pictures, you’ll find that the queen is sometimes a little longer than worker wasps, perhaps a quarter inch. And in some varieties of wasps, queens have a pointed lower abdomen and narrow waist that the non-royal members of the colony do not have.
You might find dead bees near the front door of a house or the back porch. This is often caused by an automated porch light that comes on before dark, becoming brighter as the sun sets.
Some may travel as far as 1000 metres from the nest.
approximately 12 to 22 days
A hornet’s life varies depending on species. An average worker has a lifespan of approximately 12 to 22 days, while the queen can live up to a full year, meaning that fertilized queens are the only hornets actually to survive the winter.Feb 22, 2021
Wasps will ignore some objects regardless of how attractive they look and move to some. Can wasps see in color? Yes, the only color they cannot see is red. In fact, color influences their behavior.
Each colony of social wasps such as hornets, yellow jackets and paper wasps lasts only one year. Each nest is built from scratch each year. The previous year’s nest can not be reused and in the case of hornets, disintegrates quickly in late fall winds and rain.
Our existing research shows that honeybees and wasps can learn to recognise human faces. Other evidence – from a US research group – shows that paper wasps (Polistes fuscatus) can very reliably learn the faces of other paper wasps, and appear to have evolved specialised brain mechanisms for wasp face processing.
With low rainfall and warm conditions, more of them than usual could start nests and lay eggs. This resulted in a bumper crop of the little menaces. Climate change is helping out the hornets and wasps.
All wasps and hornets are beneficial, said Wizzie Brown, Texas A&M AgriLife Extension Service entomologist, Austin. Homeowners can appreciate that they protect gardens and landscapes from pests like caterpillars, spiders and aphids and pollinate blooming plants, but a sudden sting can erase that goodwill quickly.
Hornets overwinter near small crevices in home siding, tree bark, and rotten logs. But, the most likely place to find their nests is on the branches of trees and large outdoor, tree-like shrubs. In late spring, they build paper nests in tree branches and underneath eaves.
Wasp repelling plants
Plants such as citronella, thyme, and eucalyptus naturally deter insects like wasps and hornets. Growing these plants in your backyard will not only keep away these pests but also add beauty to your garden.
Hornets make a loud flight noise and can be heard from inside a building, if the hornet’s nest is within the wall cavity. If the hornet’s nest is near your home, keep nearby doors and windows closed.
