What type of agent is commonly used to treat a wasp nest?

The most effective method for treating a wasp nest is to use an insecticidal spray. This type of agent is specifically designed to quickly eliminate wasps and their nests. Insecticidal sprays often come with a long-reaching nozzle, allowing the user to apply the product safely from a distance, reducing the risk of being stung. These sprays typically contain active ingredients that target the nervous system of the wasps, leading to their quick demise.

While freezing agents can incapacitate wasps, they might not always ensure complete eradication of the entire nest or can be less effective in larger colonies. Granular bait and liquid bait are also primarily used for different types of pests, such as ants or cockroaches, and are not effective against wasps that fly in and out of their nests. This underscores the reason why using an insecticidal spray is the preferred choice for addressing wasp infestations effectively.
