Insect bites are often annoying, and bites from some types of mosquitos and ticks can cause serious health problems. To avoid being bitten, people often use insect repellents. Most insect repellents contain a substance called DEET (C12H17NO), which is made by combining meta-toluic acid (C8H8O2) and diethylamine (C4H11N). DEET is a useful ingredient in insect repellents because insects dislike its smell.In the chemical reaction described in the passage, which of the following are reactants? Select all that apply.DEET (C12H17NO)meta-toluic acid (C8H8O2)diethylamine (C4H11N)Submit

InsectsBy midsummer, biting insects like mosquitoes and fleas are out in full force in most parts of the United States. Unless you plan to stay inside, you will likely head to the store to load up on bug repellents. An excellent natural alternative to chemical bug repellents is the use of essential oils. Such oils, taken from natural substances, have been used for centuries for this purpose.Essential oils repel insects because they block their sense of smell, fooling them into thinking they should go elsewhere for their meal. For example, to get rid of ants around the house, put drops of peppermint oil across the ant paths. This confuses the insects' scent trails and makes it impossible for them to find food. Similarly, you can confuse biting insects by wearing essential oils on your skin that do not allow them to sniff you out.Oils that are strong smelling work best as bug repellents. Some of the most effective are peppermint, citronella, eucalyptus, and lavender. Applying a watered-down essential oil to the warmest exposed areas of your skin (backs of the knees, behind the ears, etc.) will discourage bugs from using your skin as a landing strip. However, make sure not to use sweet-smelling or perfume-like oils.14Select the correct answer.What is the main idea of the passage? A. Insects usually have a strong sense of smell. B.

All-Natural Pest PreventionLee Washington1As the weather becomes warmer and people travel outside more often, daring pests creep indoors to explore kitchens and pantries. It is important to know that insects and mice can contribute to the spread of germs and diseases. At the very least, these pests can damage food supplies or cause itchy bug bites. From the largest mice to the tiniest fleas, these creatures can turn a peaceful home into a crawling nightmare!2Many people, however, hesitate to use commercial sprays near children and pets or in places where they store food. The harsh chemicals in these sprays can cause serious injuries if they aren’t used properly. Luckily, there is now another choice for people who want to avoid these dangerous chemicals. The experts at Growing Garden Supply are happy to help you discover all-natural ways of keeping these creatures outdoors, where they belong.3This week, pots of peppermint and lavender plants are on sale. These herbs not only let off fragrant scents, but they also can be used to keep pests out of your home.

Sprinkle a few along the edge of your home to discourage pests from entering. Happily, mint leaves are completely safe for humans to eat. Try some in a cup of tea, or use them to add flavor to baked goods.4After seeing the great results from the mint and lavender plants, why not start an entire garden of plants that are unappealing to pests? Growing Garden Supply has an excellent selection of bitter cucumber seeds and garlic bulbs.
