They’re insect larvae
Almost always mosquito wrigglers or red bloodworms — not parasites, but proof your tank is open and dirty.
KaamGenieWorms in Your Water Tank?!
What those wrigglers really are — and how to clear them fast.
The truth
How they get in
A gap let them breed
A loose lid, unscreened overflow or open vent lets an adult insect in to lay eggs on still water.
Why it matters
A dengue breeding site
Mosquito larvae mean your tank is breeding dengue — a real Delhi risk. Don’t drink the water until it’s cleaned.
The real fix
Skimming won’t work
Eggs and sludge stay behind, so they return in days. You must drain, scrub, vacuum and disinfect.
Keep them out
Seal every opening
A tight lid and fine mesh on the overflow, vent and inlet stop insects getting back in for good.
