Which statement is true about fumigation to control wood destroying beetles?

It will help control existing infestations but cannot protect wood from future attacks.

Fumigation is about eliminating pests that are currently inside the wood. The gas penetrates deeply and can kill the beetles and their larvae that are present at the time of treatment, reducing the existing infestation. But there’s no lasting protective barrier once the fumigant dissipates, so wood can be attacked again in the future if conditions allow. In short, it removes the current problem but does not guarantee wood will never be attacked again. It’s not just for fungi, and it doesn’t make wood stronger or provide long-term protection.

It guarantees wood will never be attacked again.

It only targets fungi.

It strengthens wood against future attack.
