What type of insecticide can kill many different types of insects?

Broad spectrum insecticides are designed to be effective against a wide range of insect pests. This includes many different species, making them versatile choices in pest management. Their chemical composition and mode of action allow them to target multiple types of insects rather than a specific group. This attribute is particularly advantageous in situations where multiple pest species are present, as it can simplify pest control strategies and reduce the need for multiple products.

In contrast, selective insecticides are formulated to target specific pest species, which limits their effectiveness against a broader range of insects. Residual insecticides, while capable of remaining effective for an extended period after application, do not inherently denote a broad spectrum of effectiveness; they may still focus on specific pests. Systemic insecticides work by being absorbed into the plant or animal tissues, affecting pests that feed on them, but they do not necessarily classify a broad fighting capacity against various insect types.
