Keeping a lush, well-manicured lawn requires hard work. Once the weeds are under control, the insects begin their destruction. It's a never-ending process. Chemicals that eliminate insects kill the beneficial bugs also. Chemicals are detrimental to the earth, people and pets. However, they work fast. Scientists labored many hours to develop the right chemical solution to kill insects. If you do not want to bring chemicals into your environment, try some of the many organic methods.
Kill insects in the lawn with a pesticide. Many pesticides are manufactured to protect agricultural crops, home turf and gardens. The U.S. Environmental Protection Agency (EPA) regulates the usage of such products. All manufacturers must register pesticides, and consumers must use them in accordance with the EPA's standards. Always read and follow the instructions on the label of these products. Chemical pesticides contain known carcinogens, making them hazardous to humans and pets. Chemicals also end up in lakes, streams and oceans.
Kill insects with organic pesticides. In response to the green movement, products containing nematodes are now available in gardens centers. Nematodes are microscopic, transparent multicellular organisms. Under a microscope, they look like worms. Some parasitic nematodes are beneficial, and used to manage harmful insects in the lawn and garden. Nematode products are available at any garden center.
Spray the lawn with an insecticidal soap. Add 2 tbsp. of liquid soap to 1 gallon of water. Mix gently. Pour solution in spray bottle. To increase effectiveness, add herbs and spices known to repel insects to the soap solution: garlic, onions, horseradish, ginger, rhubarb leaves, cayenne and other hot peppers. You may choose any variation of these items. It isn't necessary to use all of them. Put them in a pot, cover with water and bring to a boil. Remove from heat and let cool overnight. Strain and add herb and spice water to the soap solution.
