How long do fabric moth eggs remain viable?

I have a moth eaten old wool blanket that i recently used to protect my floor while using an angle grinder. Then i pulled it out as something to sit on during the eclipse. And i noticed it was a lot MORE moth eaten than it had been a couple of months ago, and there were visible remains of pupae in places.

So i washed it, and dried it, which i hope removed/killed the eggs. But I’m wondering if i need to find a new place to store it. I don’t want to use moth balls where i was keeping it, as there’s not a lot of ventilation and i don’t want to be breathing that stuff. And I’m dubious i can clean the nook it was in well enough to remove all the eggs.

So my thought was to store it elsewhere for “long enough” for the eggs to die. How long is long enough?

Just washing in water may not eliminate the eggs. Dry cleaning or using insecticides (natural or artificial) may be required. Eggs will generally hatch in a week or two but of course even a single moth can lay more eggs. Storing the blanket or clothing in a sealed container with an anoxic environment (nitrogen or carbon dioxide) should eliminate the eggs or hatched larvae. If you don’t want to use mothballs or synthetic insecticides, camphor or lavender oil are reported to work, as is introducing the parasitic tricogrammatid wasp (Trichogramma evanescens), whose larvae will consume the wasps.

If you have a big enough freezer, sub-zero temperatures should kill them on the blanket.

Some diatomaceous earth liberally distributed with a powder sprayer should clean up your nook. Re-apply the DM daily, vacuum up after a week.

I have one closet, plus the garage, where we hang No Pest strips. That gets rid of the moths and the larvae.

Alright, excellent, that should get the moth population under control. Now, what can I get that will eat the wasps? I’m thinking some kind of bird?

Cedar could work.
But I’m a believer in moth balls.

I’ve used them for years, judiciously.
Ain’t killed no one yet.

If you just can’t abide them. Big plastic container with tight lid. Put blanket and moth crystals in and leave til you’re planning on use. Then wash and dry again.

Good luck.

Given that they are about 0.02 inches in length, you could probably suck them up into a filter and spread them on toast with a bit of marmalade without notice for some extra protein.

I can put the blanket in a place with moth balls. I just can’t put mothballs where i used to store the blanket. That’s why i want to know how long the eggs will be viable there, so i know how long i have to wait before putting the blanket back.

I’ll consider diatomaceous earth, but i didn’t think it will work, either. I’m hoping to just wait it out.
