In theory, there should be no difference in the health risks associated with the use of either chemical or biological pesticides when used according to label instructions. However, we have to accept that there will be occurrences where products may not have been applied appropriately. The negative health effects associated with chemical pesticides include, dermatological, gastrointestinal, neurological, carcinogenic, respiratory, reproductive, and endocrine effects. High occupational, accidental, or intentional exposure to pesticides can result in hospitalization and death.
While chemical pesticide residues from appropriately applied products do not exceed the legislatively determined safe levels, these may underestimate the real health risk if simultaneous exposure to pesticides from two or more sources occurs (e.g. from chemical application inside the home, and via residues on food products). Often, the effects of chemical pesticide exposure can go unnoticed, but the long-term effects can result in significant health impacts.
Conversely, due to its non-toxic nature, cumulative exposure to biological products such as Aprehend via different sources, would not increase the risk of health impacts.
