pine cone from yard for parrotlet safe?

picked some pinecones from the tree in our yard. wondering if they're safe if i scrub and then bake them. i made sure it doesn't have moss or mold.

but im most worried about avian flu and if baking will be enough to kill it. they've been in my house for a few weeks now. but also our yard faces a highway.

i can't find much info specifically on this. i think boiling and baking should be fine. versus buying them, i know where they're coming from, that they're clean, etc. it's also less waste.
