As its name implies, an insecticide kills insects by means of chemical exposure. It destroys all forms of an insect species, from the eggs and larvae to the adults. Therefore, an insecticide differs from a repellent, which only keeps the insects away from a designated area. Insecticides come in many forms and fit within an integrated pest management strategy with pesticides, herbicides and fungicides.
Insecticide Use and Abuse
Most insecticides come in spray form, such as aerosol cans and crop dusters. Insecticides have the potential to eradicate many beneficial insect species and alter an ecosystem, so it takes careful planning and application when using any type of insecticide. Insecticides contain toxic chemicals that harm people and animals; however, the labels include instructions and precautions for safe use. In addition, wash any fruits or vegetables that grow in areas of application.
Types of Insecticides
From fumigants to residuals, insecticides eliminate certain insects and offer curative maintenance for infestations. Apply all insecticides according to the instructions on the label, and always wear protective gear to avoid contamination. Depending on the type of insecticide, it can take anywhere between hours and seconds for it to take effect.
