Permethrin does kill yellow jackets as well as hornets, ground bees, wasps, and other stinging insects. You can discourage yellow jackets from nesting in trees and shrubbery around your yard by spraying them with permethrin as well.
Trees provide food, shelter and a nest site for Woodpeckers.
Yellow Jackets: Yellow jackets are small (half-inch long) wasps marked with yellow. Colonies are initiated by overwintering queens that make paper nests underground, but occasionally in hollow trees, wall voids and attics or on a branch over a stream. A fully developed nest may contain from a few hundred to many thousand adults. Yellow jackets feed on a variety of pest insects, but will also forage for meat or soft drinks at picnic, camp and garbage sites. This habit often brings them into close association with people. Good sanitation in picnic areas can help reduce problems with these pests. Solitary scavenging yellow jackets are usually non-aggressive unless handled, but become very aggressive as a group if they believe their nest is threatened. Yellow jackets will vigorously pursue an intruder who threatens their nest and are generally considered the most dangerous of the social insects. I cant post the picture for you, but yeah these little guys chased me tonight when i was mowing my yard and one got me....little sucker.
Woodpeckers are looking for food. They are looking for insects in the bark/tree.
Yes, bees pollinate yellow dandelions. The plants in question (Taraxacum spp) provide early spring-flying beneficial insects, such as bees, with nectar and pollen. They reproduce by beneficial pollinators, self-pollination and wildlife- and wind-dispersed seeds.
Yes they are small insects that feed on dead plants and trees as well as dead parts of living trees. They are light yellow to black with clear to smoky gray wings.
Some birds, like yellow-bellied sapsuckers, can drill holes into trees and drink the sap, so yeah, they harm trees.
Aphids and mealybugs have been known to eat holes in fruit including oranges. Aphids if not controlled can cause a lot of damage to orange trees.
Yellow-billed hornbills sleep by roosting in trees at night. They typically find a secluded branch or crevice to perch on, where they can rest and stay safe from predators while sleeping. During the day, they are active and forage for food such as insects, fruits, and seeds.
Woodpeckers make holes in trees, while others just find holes in trees
Birds peck holes in sweet gum trees to feed on the sap that flows out. The sap provides a good source of nutrition and energy for the birds. Additionally, the sweet gum tree sap may attract insects, providing the birds with an additional food source.
Yellow-eyed juncos primarily eat a variety of insects and spiders they find on the ground, along with seeds and berries. They have been known to forage on the forest floor and in shrubs or trees for their prey.
