However, some users might find that while it effectively kills pests, its residual effect may vary depending on the specific environment and pest types, which means repeated applications might be necessary in heavily infested areas. While it performs well on various surfaces, care should be taken around porous materials, as performance may differ. Also, like with any pesticide, there could be concerns about safety and environmental impact, particularly for sensitive individuals, so it's important to follow the usage instructions carefully.

However, there are a few considerations to keep in mind. While it is effective, its chemical formulation means users need to handle it with care to avoid any adverse effects on health and the environment.
