I recently deployed some parasitic wasps (Aphidius colemani) in my hydroponic greenhouse to eliminate my aphid problem. The brown aphids are ones that have been infected by the parasitic wasps, the wasps lay eggs inside of the aphid and once ready they emerge from the aphid leaving a mummified husk behind. Each wasps can lay hundreds of eggs in a relatively short period of time, I released 1000 wasps and they have now multiplied into many thousands after killing thousands of aphids!
Thought this would be interesting to share, it’s pretty cool and a great way to eliminate aphids without using pesticides!

These killed my 20 cucumber plants within a span of 1 week. My 3 months of work got wasted. They are a nightmare for me. They multiply exponentially each day.
50:50 water/alcohol + little dawn dish soap (blue one works best) for dispersion will suffocate them as it dries off.
