Canola oil appears to have no adverse effects on humans or the environment.
Canola oil is considered safe for human consumption.
Scientists believe that canola oil repels insects by altering the outer layer of the leaf surface or by acting as an insect irritant. The products are applied either with spray or irrigation systems. No harmful health effects to humans are expected from the use of canola oil to repel insects. Information available from published studies indicates that canola oil's nutritional and toxicological profiles are similar to those of other vegetable oils that are used as food. Adverse effects to the environment or to organisms other than insects are not anticipated because of the low toxicity of canola oil and its rapid decomposition in the environment.
