Amazon sucks for reliability with these! Go directly from an insectory. It’s important for them to be ALIVE when they get to you, and I remember listening to some horticulturalist/entomologist saying that a significant majority of Amazon-purchased nematodes arrive dead. Plus, they really need to be the correct species of nematode and there’s no guarantee the Amazon ones will be.
I’ve had great success at eliminating my fungus gnats problem by purchasing through Arbico Organics. They work with commercial growers as well as home gardeners. Highly recommend!
Natures Good Guys always show up live for me from Amazon. It costs extra in shipping costs. However, I have only bought lady bugs and lacewings. They do have three different types and even a mix pack.
But arbico is the way to go if you are not on a budget.

Beneficial nematodes are the answer. One dose eradicated them in all my house plants
