What is the primary route of entry for borate termiticides?

The primary route of entry for borate termiticides is oral. Borate compounds work effectively when they are ingested by termites. This is because these substances act as stomach poisons, meaning that when termites consume materials treated with borate, the chemicals interfere with their digestive processes and ultimately lead to their death. Borate compounds are especially favored in termite control due to their low toxicity to humans and pets compared to more conventional insecticides, making them a safer alternative for managing termite populations.

While other routes of entry, such as topical or surface absorption, might play a role in how certain insecticides affect pests, for borates, ingestion is the most significant and effective method of action. This selective mechanism of treating termites through their feeding behavior underscores the effectiveness of borates in long-term pest management solutions.
