For adults, sweet baits or pheromone traps are commonly effective. Larvae stages might not be lured by food but by mimicking the sound or vibrations of their host trees.

The eggs of yellow spotted longicorn beetle are typically laid in the crevices of tree bark, especially in hardwoods like the fig tree. Larvae reside within the wooden interior, forming tunnels as they feed on the wood. To find these, one would have to carefully examine tree trunks and branches for entrance holes or wood frass indicative of larval presence. Pupation occurs within the wood as well, necessitating close inspection of the same areas if searching for pupae. Mature yellow spotted longicorn beetle generally emerge onto the tree bark or surrounding foliage. Therefore, to spot adult yellow spotted longicorn beetle, search the surfaces of trees and neighboring plants, particularly during warm weather when they are more active.

Adult yellow spotted longicorn beetle are typically active during the warmer months and can be found during the day, although some may also be active at dusk or at night. Larvae might be present year-round but are more likely to be found when they are active inside host trees during warmer temperatures.

Warm, dry conditions are generally best for finding adult yellow spotted longicorn beetle, as they are less active in cold or rainy weather. Larvae development can also be influenced by seasonal weather patterns, which affect the physiology of their host trees.
