Deltamethrin is a synthetic pyrethroid insecticide widely used in agriculture, home pest control, foodstuff protection, and disease vector control. As a type II pyrethroid, it's hydrophobic and acts by causing a severe delay in sodium channel inactivation, leading to persistent nerve membrane depolarization. While effective, it's crucial to manage its presence in food and water. Studies suggest potential toxicity through oxidative stress, which can be alleviated with Vitamin supplementation.
