What are the two categories of liquid termiticides?

The correct choice identifies the two categories of liquid termiticides as repellents and non-repellents. This categorization is essential in pest control strategies, particularly regarding effective termite management.

Repellent termiticides create a barrier that actively deters termites from entering a treated area. They are helpful for preventing infestations since termites tend to avoid these chemical barriers. However, a drawback to repellents is that they may not kill termites that come into contact with the chemical. Therefore, their effectiveness is largely dependent on the thoroughness of application.

On the other hand, non-repellent termiticides do not offer an immediate deterrent effect. Instead, they allow termites to pass through treated areas without realizing the presence of the chemical. Once termites contact these chemicals, they can spread it to other colony members, leading to population control or elimination. This characteristic makes non-repellents especially effective in controlling existing infestations, as they can impact the hidden or undetected termites.

Understanding these two categories is crucial for pest management professionals, as it influences the choice of products and application methods for termite control. The other options, while they may describe aspects of termiticides, do not accurately represent the primary and functional classifications of termiticides in the context
