Beetles are found in almost every habitat except the sea and the polar regions. They interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Many beetles enjoy human gardens, since gardens are typically moist and filled with easy sources of food. Some, like the flour and grain beetles attack food products in homes. They also damage food in production facilities and stores.
When a bite occurs, the blister beetle releases cantharidin, a poisonous chemical that causes human skin to blister. The blistering of the skin disappears on it own over time. It's rare, but blister beetle bites can be fatal to humans if a person experiences a severe allergic reaction.
CONTROL AND MANAGEMENT MEASURES:
Good sanitation practices and removing foods that support beetle development and reproduction can be accomplished with a vacuum or another form of mechanical removal.
Pheromone based traps can be used for identification. Insect Growth Regulators (IGR) can be used to control beetles.
