Moth maggot invasion of pantry.

[The Pastor]

TURN THE LIGHTS OUT? the moths won't hang around anymore!

Maybe a combination. Clear out the cupboards and fire bomb the lot. Then start all over

done that a lot of times.

Go to the warehouse and buy some of those tallish rectangular storer things, you know, the ones you pour your cereal from. Cheap. That's the only way really.

Maybe try some plastic, sealable containers. You probably already have some food items in these containers, but sealing all food items would be a good start.

Guess what?
We had Eggs Zachary the same thing happen in our pantry a couple of years back, and the little buggers somehow managed to get into sealed containers, munch through plastic and/or foil bags, and ruined all sorts of foodstuffs. And no, they weren't weevils whose eggs were already present in those things. For a while, the pantry was renamed "The Moth-Breeding Chamber", but we didn't get any of those kewl two-person flying machines like they had in "Lexx", just your regular, run-of-the-mill native moths.

How did we fix it?
Nuked everything, chucked out all the infested food, etc. and washed everything down with stuff.
And tried to convince people to SHUT THE FRIGGIN' DOOR PROPERLY!

I have a suspicion it's all to do with pheremones, and familial memories (if there is such a thing). Once the lepidopterae designated The Moth Breeding Chamber a suitable BonkingBox, they seemed destined to return there, probably because of all sorts of invisible signs we weren't aware of. Eliminate a generation, and ruthlessly kill any MothProstitutes/Gangbangers you find loitering around, and they should clear off and go back to other pursuits, like watching "Mothbusters", or texting each other about parties to crash.

Maybe they just moved on from our place and went to RM's house....
