Contact effects occur where?

Explanation:
Contact effects happen at the point where the organism first meets the chemical—the site of exposure. This is the initial interaction between the pest and the pesticide, such as the skin, exoskeleton, or mouthparts coming into contact with the product. Some pesticides act immediately right at that contact point, while others may still need to be absorbed to have broader effects, but the defining moment is the interaction at the exposure site. Effects occurring only after the chemical is absorbed and travels through the bloodstream or throughout the body are not considered contact effects.
