Mosquitoes in hydroponic herb garden
I just purchased a simple Aerogarden (a commercially-packaged hydroponic garden) and am trying to grow a few herbs. Unfortunately, since about a week after initial planting, we have been kept up nights by mosquitoes, and I suspect that they are breeding in the Aerogarden despite the bubbling action in the reservoir.
I have two questions:
1) Does it seem plausible that mosquitoes are indeed breeding in the Aeorgarden?
2) Various posts here and elsewhere have suggested Bti (Bacillus thuringiensis israelensis), but I could not tell from those posts whether it was considered safe for treating water used to grow food plants. Is Bti considered safe for treating water used to grow herbs? If not, are there other solutions out there?
Thank you in advance for any help you can provide.
