What do desiccants do to insects?

Desiccants are substances that promote drying and are particularly effective against insects because they work by damaging the protective waxy coating on their exoskeleton. This waxy layer is vital for maintaining moisture within the insect's body. When desiccants come into contact with insects, they absorb moisture and break down this protective barrier, leading to dehydration. As a result, the insects lose moisture rapidly, which can ultimately lead to their demise.

The effectiveness of desiccants in pest control stems from their ability to compromise this critical aspect of insect physiology, making them a popular choice in various extermination methods. This specific interaction highlights the importance of understanding how different pest control methods function to effectively manage and eliminate insect populations.
