What's That Bug? does not endorse extermination

This morning I found many of these dead under a hanging petunia basket, many dead in the family pool, and one crawling and almost ready to drop in the pool. They’re all about 3/4 inch long. I don’t know if they dropped from the basket because I had sprayed ant insecticide onto the slab(boy, we have been overrun with ants!)so they may have wandered into the dead zone from somewhere else.
They crawl like maggots but these don’t look like the housefly white larva.

Black Soldier Fly Pupa

Hi Gene,
We have categorized this as a Maggot on our website.  It is a Black Soldier Fly Pupa.  The Larvae of the Black Soldier Fly are very common in healthy compost piles, and they often wander away from the compost when it is time to pupate.

    why and how are these pupa things getting in a toilet ? do the swim up in the water in the toilet? could they live in your plunger in the bathroom if the fly laid eggs there?
    thanks, just a little freaked out.

    I recently purchased an RV, and about a week/2 later I have these crazy Lil critters. I have put the RV on a permanent septic system(no longer using the holding tanks solely). Could they be coming from there? And what is a good deterrent?

      Did you ever figure out where they’re coming from? Because they are just now appearing up in my camper as well.

    I found TONS of these squirming around in the mulch and dirt bottom of my parakeet aviary. SO GROSS!!! I can’t treat because the insecticide will affect my parakeets! Ugh.
