What are the most effective insecticides?
If you are plagued with bugs in your home or yard, using a natural insecticide will help you fight off the pests. Many people prefer using either a natural insecticide or an organic insecticide, as the harsher, chemical-laden synthetic insecticides can pose dangers to both people and pets.
Rotenone, nicotine and pyrethrum are examples of natural insecticides. They are derived from plants, and these products are, for the most part, very safe to use around people and pets. However, overexposure to heavy concentrations of rotenone and nicotine can have side effects on both humans and animals.

Many people have found that dishwashing soap is a good insect repellent. They simply put a few drops in a spray bottle, mix with water and spray on the plants. This is an especially good way to manage a massive aphid invasion. If you use this technique, make sure that you spray the underside of the leaves, to which the aphids attach themselves so they can drink the juice from the leaves.
Some people prefer to use an organic insecticide. These are similar to natural insecticides, using plant-derived compounds to repel bugs or fight off insect invasions. People have also successfully used a concoction of garlic, onions and black pepper. They put these items in a blender with water, and then spray the liquid on the plants. Organic pest control applications must be repeated several times a week to deal with the problem effectively.
DDT is a synthetic pesticide, heavily used in the past. Though it was very effective, it also caused serious problems in the food chain, since DDT remnants remained in the tissues of the insects that ingested it. The animals that fed on the insects actually died from the toxic effects of DDT ingestion. It is now completely banned in many countries, though it is still used in nations where malaria remains a problem. Even then, DDT insecticide can only be used inside the home to control mosquitoes. It cannot be used in agriculture anymore at all.
Aerosol insecticides are applied via spraying. They can be released from a small spray can or hose or, if a large area must be covered, scattered onto fields from crop dusting airplanes. Aerosol insecticide sprays make it easy to ensure that the potent chemicals are evenly distributed over the plants. For this reason, many commercial insecticides come in aerosol cans, including both natural and synthetic products.
