Bonide Captain Jack's Organic Fungicide Insecticide Miticide - Liquid Concentrate - 16 fl oz

I use this on my viburnum shrubs, which are susceptible to caterpillars in the spring. It works well to keep them away. The concentrate is very economical to use. I spray the soil and the branches before they leaf out. Note: I spray in the late afternoon/evening. I find customer service people very helpful and knowledgeable when I call with questions too!

Neem oil won't solve every problem your plants might face, but it covers many of them. Tough problems. It's one of the catch-all solutions. Be aware that it will also harm beneficial insects, so use it when you need it, where you need it. When it's not needed, the concentrate takes up very little space on your critter-chaser shelf.
