For major pest infestations the following can be used:
Organic Pest Control Methods:
1) Spray Insecticidal Soap directly on the the bugs (I do this late in the day and rinse off the next morning so the sun doesn’t burn the plants). Do repeated treatments every few weeks until they are gone. For a homemade soapy water spray, I mix up some castile soap with water and neem oil (I do 1 tsp of Dr. Bronner Soap + 1 tsp Neem Oil to a quart of water in a spray bottle, per the instructions on the neem oil bottle, but there are many recipes online for homemade insecticidal soap that would probably work just as well).
Alternately, you could buy a pre-mixed Insecticidal Soap.
These are the brands I have used:

2) For Caterpillars/Worms I use the organic products Spinosad and/or “Bt” (Bacillus Thuringiensis). I only use them for severe infestations that can’t be controlled by routine hand picking. I spray it in the evening when bees are not active and only spray it on the affected plants. These are the ones I have used, but there are other brands that would also work (Note that these are concentrates, meant to be mixed with water following the instructions on the label): Spinosad: https://amzn.to/3IOmzRw

Shade Cloth (I use between 30% and 40% shade cloth): https://amzn.to/3C2z35a
Here are links for many of the products I use in my vegetable garden. Note that a lot of these items, like the fertilizers and the trays/saucers, have gotten much more expensive lately (like everything else). I shop around to find the best prices on the items and if I can’t find something at a reasonable price then I will just do without or find a substitute):

In addition to the above fertilizers I occasionally use these seaweed and fish fertilizers to give my plants a boost of nutrients. I also use some of the seaweed fertilizer (half-strength) on my seedlings right after I transplant them (Note: I don’t use fertilizers with fish in them for seedlings):
Maxicrop Seaweed Fertilizer (Powder): https://amzn.to/3uWO9ak
Maxicrop Seaweed Fertilizer (Liquid): https://amzn.to/37uA0JJ
Neptune’s Harvest Tomato & Veg Fertilizer 2-4-2 (Note: this formula is best for first few weeks of plant growth, as it encourages lots of green leafy growth. For fruiting/flowering plants, I switch to the Rose & Flowering formula after the first few weeks. Also, this contains fish and the smell attracts animals, which will dig up the plants trying to find the source of the fish smell, so I use it early in day and water it in just before dark to minimize the smell). https://amzn.to/3r8OJ40 Neptune’s Harvest Rose & Flowering Formula 2-6-4 (Note: this formula is best for later stages of plant growth to encourage more flowers and fruit to grow. This formula also contains fish so everything I said above about attracting animals applies to this formula too). https://amzn.to/3KqBino
