Regardless of where an infestation has started evidence will eventually emerge in these places.
My hardwood floors have bug holes.
Start your search around the floor s edges and under windows where adult beetles tend to fly towards light.
If the floor is infected with bettles or termites when will i see them.
This how to refinish wood floors article will show you how to do just that.
I just had my new hardwood floor installed.
Now back to the floor.
I have seen what you described many times.
These small beetles grow to about 1 8 inch long as adults.
So laminate starts to sag and blister.
The floor was installed for a good deal.
First the adult beetle lays its eggs on the wood surface then the larva bores through.
The floor is red oak.
If there are termites you will see holes in the food or the wood will seem layered with brown frass.
New flooring is installed and finished and then months or even years later small holes develop.
If you have hardwood floors the infestation can t be seen even for some years.
Larvae hatch enter the wood and feed excreting sawdust like waste called frass that is often visible on the floor.
But i do see some holes in the wood similar to pictures on the web for powderpost beetles.
I live in texas.
These beetles grow to 1 2 to 1 inch long and only attack softwoods primarily pine.
Additionally old house borer exit holes are typically oval with ragged edges.
The insects emerge as adults through tiny round exit holes.
Most hardwood floors have been dried and aged but were part of a tree and then board at one time.
These are emergence holes made by adult beetles leaving the wood.
Small holes caused by woodworm are typically found below the floor s surface.
The holes are created when the adult beetle emerges from its underground womb and they can also cause a lot of damage from within the flooring too.
If you see larger holes up to the size of a dime this could indicate you have old house borers.
But afterwards floors be one weaker.
But as long as the damage is shallow in the coating and not in the wood itself you can renew the hardwood floor by adding a new coat of polyurethane right over the old finish.
Floor tiles become loose if termites damage joists floor supports the floor may start sagging.
I am now concerning that they may used lower grade of material.
Of course if you have found such a rotten joist or floor board you can try to sand it to living tissue and cover with special chemical against termites.
Hardwood floor refinishing can help you get rid of those unsightly scratches and marks.
