Now back to the floor.
My hardwood floors have bug holes.
Additionally old house borer exit holes are typically oval with ragged edges.
But i do see some holes in the wood similar to pictures on the web for powderpost beetles.
If there are termites you will see holes in the food or the wood will seem layered with brown frass.
Larvae hatch enter the wood and feed excreting sawdust like waste called frass that is often visible on the floor.
These are emergence holes made by adult beetles leaving the wood.
Floor tiles become loose if termites damage joists floor supports the floor may start sagging.
These beetles grow to 1 2 to 1 inch long and only attack softwoods primarily pine.
If you see larger holes up to the size of a dime this could indicate you have old house borers.
But pay a close attention whether the joist is load bearing or not.
The insects emerge as adults through tiny round exit holes.
Small holes caused by woodworm are typically found below the floor s surface.
Their damage to hardwood flooring happens when their larvae bore into the wood through surface cracks.
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.
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.
New flooring is installed and finished and then months or even years later small holes develop.
I have seen what you described many times.
This how to refinish wood floors article will show you how to do just that.
Hardwood floor refinishing can help you get rid of those unsightly scratches and marks.
Start your search around the floor s edges and under windows where adult beetles tend to fly towards light.
Termites may eat the backing of the laminate floors.
I just had my new hardwood floor installed.
The floor is red oak.
The floor was installed for a good deal.
I am now concerning that they may used lower grade of material.
So laminate starts to sag and blister.
Regardless of where an infestation has started evidence will eventually emerge in these places.
But afterwards floors be one weaker.
If you have hardwood floors the infestation can t be seen even for some years.
These small beetles grow to about 1 8 inch long as adults.
First the adult beetle lays its eggs on the wood surface then the larva bores through.
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.
