What is one of the disadvantages of pyrethroid termiticides?

One of the disadvantages of pyrethroid termiticides is their limited stability in sunlight. This characteristic means that when exposed to direct sunlight, these chemicals can degrade more quickly, reducing their effectiveness over time. This stability issue necessitates careful application and potentially more frequent treatments when using pyrethroids in outdoor environments where sunlight exposure is significant.

In contrast to this option, while pyrethroid termiticides do have some efficacy limitations with certain types of termites, such as drywood termites, their liquid form can provide substantial advantages. Moreover, concerns about biodegradability are less relevant in this context than the immediate concern of chemical stability in sunlight, which directly affects the treatment's longevity and overall effectiveness.
