Our company produces bags for food makers. We pack our products on wooden pallets and we store fumigated (heat treatment) pallets in a warehouse before we use them for shipping.
I am looking for a practice or an instruction about preservation of fumigated wooden pallets, e.g. stocking condition and duration (practical time of storing before possible re-infestation).
I think it's okay to post this in the pest control section. Please move if I was wrong.
P/S. I read somewhere they said that the critical time of post-fumigation was 21 days and after that, pallets had to be retreated.
Thank you in advance.
