If there are small gap in the wooden floor for them to hide from the light. They can infest in there.
I didn't change my wooden cupboard, I spray insecticide into the small gaps and killed them all.
I eats, shoots & leaves
My tip is to make a perimeter around your bed by ant chalk, of course you have to make sure your bed/mattress are free from bed bugs.
That way you can hunt the bugs at daytime, and won't be bothered by it when you sleep.
My house got some old wood furniture which I took over from my parent house when they sold their house. Even the mover also says it's good kind of wood (teak?) and I hopes no bed bugs (or termites) in my house after I return from any trips. I always try to keep my house bugs free, lizard and spider ok.
Only Sony device mostly, haha!
