It looks like our spinach has been infested by something. We just planted two weeks ago and half of the leaves look wilted. When i looked closer it looked like there was something within the leaf which now had a translucent film and i saw two white worms wiggling in there. What can i do before the rest of the crop is destroyed?

Welcome!

Looks like spinach leafminers. You can pick off the infested leaves and destroy them which breaks the life cycle (you won't likely want to use those leaves but leaving them on the plants allows the larvae to become adults and reproduce). A non-systemic insecticide probably won't help at this stage because the larvae are protected inside the leaves and it would also potentially kill their natural predators.

To avoid this problem in the future us a floating row cover (such as Remay) and completely cover the plants so the insect cannot lay eggs on your plants. Good luck.
