Eubacteria fall into four primary categories, which are gram-positive eubacteria, proteobacteria, cyanobacteria and spirochetes. Eubacteria are more common than archaebacteria, which are closely related members of the prokaryote division. Eubacteria live in many areas around the world, including some of the most inhospitable environments.
Natural bee repellents can be purchased from stores as pesticide and chemical-free sprays, or created at home using a combination of basic household ingredients such as plant oils and herbs. Bees, like some people and animals, have strong aversions to certain scents; citronella and citrus are among the worst offenders. Some oils, such as lavender, citronella, jojoba and tea tree, repel bees as well, and can be mixed and used as a spray to keep these insects away.
Many people choose to make bee repellents at home using basic ingredients, but herbal sprays can be purchased from commercial manufacturers as well. For people who lack the time and patience to create sprays at home, this is a good way to exterminate pests without using harsh, toxic chemicals. Commercial sprays generally include oils and citrus-based scents, and are made by several different brands. Regardless of whether commercial or homemade sprays are used, they require special application techniques to bring maximal effects. Repellents should be sprayed around cracks, lines and crevices of windows, roofs and doorways, which is where bees tend to build hives. Natural repellents can also be sprayed over gardens and lawn surfaces, as they do not pose health risks to plants, flowers, children and pets.
