Thrips or/and something else ?

Hey guys,
the floor of my grow tent is full of very small balls of green shit (i suppose) and some leaves have the thrips symptoms. According to the damages on the leaves, they are not many, but the floor is getting dirty very fast. In 1 night, full of shit, and everywhere. I found nothing under the leaves.
Second, I found eaten leaves, and little green debris of leaves amongst the little balls, so that's not thrips and i saw 2 little green caterpillars. So green, you can't see them by the color.
So is it just caterpillar shit on the floor? Do they shit so much?

I had thrips in the past, i know that they are dirty, but i don't remember their shit color...

Have you got an idea?

Great thanks

Thrips leave behind black specks/globs of poop aka frass. The green balls you describe are most likely from the caterpillars. Spinosad will control both thrips and caterpillars.

Thrip frass

Great thank, caterpillar must be king shitter, because lots of frass. I have treated the plants 2 days ago and today almost no frass.

So it comes from a butterfly...but which one? Difficult to answer...

Okaaay ! I had noticed some small moths and for me they were not enemies...
Anyway i decided to buy some sticky yellow traps to hang in the grow room and tents.
I have also cockroaches with red hues, they like the tents, i wonder what do they eat, but they don't damage the weed. They like drawning in the water from the dehumidifier and i don't know how to get rid of them. I kill five a day in average. No real infestation, they are just there...
Thanks for your feedback

Edit : it seems that moths have white larvae, a green caterpillar like i saw, very uniform green, could be a defoliant noctuelle. I killed just now a little moth or butterfly (2 cm long). Very similar to a moth for me, or night butterfly. Small. The caterpillar were 2 cm long also.

I saw (and killed) a thrip. So they are not dead, shit!

Here is one caterpillar i found dying on a branch. I found 2 dead on the floor but they were greener, maybe not the same. Total in found 5 of those...But if you see the number of frass by square centimeter, they were sure more than 5.

Caterpillars are eating machines. Tomato hornworm caterpillars can erase a tomato plant overnight. Keep searching for those greenies.

They are very difficult to spot because of their color. And hard to poison i find. Thrips are dead, but those are still eating...I killed the butterfly, nothing is flying down there...

Those dainty little white moths are the ones laying eggs on plants. Get them while they are in motion!!

Spinosad should take care of the caterpillars. If not use Bacillus thuringiensis.
