True or False: Stable flies, deer flies, and chiggers inject venom when they bite.

Stable flies, deer flies, and chiggers do not inject venom in the same way that some other insects do, like mosquitoes. Instead, when stable flies and deer flies bite, they use their specialized mouthparts to cut into the skin, causing a painful reaction rather than delivering venom. Their primary action is to draw blood, which results in irritation and inflammation at the bite site.

Chiggers, on the other hand, do not actually bite in the traditional sense. Instead, they latch onto skin and inject digestive enzymes that break down the skin cells, which they then ingest. This process can cause intense itching and discomfort but is not classified as injecting venom.

While the statement might apply to certain species within the vast diversity of insects, the specific examples given in the question do not involve venom injection. Therefore, the assertion is accurately deemed false regarding these specific pests.
