What percentage of active ingredient is usually found in insecticidal dusts?

Insecticidal dusts typically contain a low percentage of active ingredients, generally around 10% or less. This lower concentration is effective for delivering the pesticide in a form that adheres to surfaces and insects while minimizing the risk of unintended exposure to non-target organisms. Dust formulations allow for slow release and provide a long-lasting effect, which is particularly useful in controlling pest populations. The bulk of the formulation usually consists of inert ingredients that serve as carriers or diluents, ensuring that the active ingredient remains effective and stable.

Higher concentrations, such as those above 10%, may be more effective in other forms of pesticides but can pose significant risks regarding environmental contamination and non-target exposure. Therefore, a lower percentage for dust formulations balances efficacy with safety considerations.
