Evidence of borer activity includes exit holes and frass. Breakout of the beetles from wood is more common when light levels are low. If you want to find borers, check behind and beneath the furniture. Look for small exit holes and wood dust (frass) around the affected areas.
The tunnels, often known as “galleries,” can eventually cause the wood to break. You know you have a problem if you find dead beetles or if the wood is disintegrating at the edges.
Females can lay anything from zero to one hundred eggs, although these eggs may be difficult to find. While they prefer untreated, rough-sawn surfaces for nesting, they will also use other nooks and crannies, such as those left by previous occupants, for this purpose.
