Using a straight nozzle is the most effective choice for treating cockroaches and ants. This type of nozzle delivers a focused, direct stream of pesticide, allowing for targeted application in crevices, cracks, and other areas where these pests tend to hide. The precision offered by a straight nozzle helps to ensure that the pesticide effectively reaches the intended surfaces or entry points, maximizing its efficacy in controlling the pest population.

In contrast, options such as a fan nozzle or an adjustable nozzle may disperse the pesticide over a wider area, which can dilute the application and reduce its effectiveness in localized treatments. A spray nozzle may provide a more general coverage but lacks the focused delivery needed for specific pest control. Thus, the straight nozzle is particularly advantageous for ensuring that treatments are concentrated where they are most needed, enhancing the overall effectiveness of the pest management strategy.
