Trapping is a common method to find adult rust pine borer, where pheromone traps or light traps at night may be effective. Adults may also be attracted to fermenting tree sap or ripe fruits.

In its larval stage, rust pine borer is commonly found in coniferous wood, particularly in pine logs, stumps, or lumber where it creates tunnels during development. Searching for larvae involves inspecting these decomposing or cut wood sources. The adult rust pine borer, however, is usually observed on or near host trees, especially around fresh cuts or injured areas on pine trees where they lay eggs. To find adults, one would look from late in the day into the evening when they are most active, focusing on areas with pine trees that have been recently cut or damaged.

The most suitable time to find rust pine borer would be the active period of adults, which typically occurs during warmer months, often in the late spring to summer.

Warm, humid, and calm weather conditions are often ideal for locating adult rust pine borer beetles as this is when they are most active. However, too much rainfall can hinder their flight.
