Larvicide - Wikipedia, the free encyclopedia

Check your local hydro shop for VectoBac. Make sure it's stored in a cooler place.. preferably dark.

It's a live bacteria... keep it in a cool dark place..

Generally the bottle doesn't come with proper applications for a Hydro or soil setup as it's used more for agriculture in controlling mosquito and black fly populations.

5-8 mL per Litre of H2o Apply once a week until infestation is gone. This shouldn't take more than 2 or 3 applications...

It's a naturally occurring larvicide... It's damn thick consistance and may make a grower question whether they should be putting something so thick into their Res. But it's a sure fire way to rid yourself of any soil based bug.

Hope this helps.
