Out doors?
Your going to get some but, for the most part. This will go away, as the bug does...
I strongly disagree with treating outdoor plants to prevent or stop what your seeing!
Nature will provide natural bug predators to counter most of what you will see.
Outdoors, I have never gotten major bug problems I get from time to time indoors.
Let it be. The problem will cure it's self. Leave any spider or such, you see in the plant, in the plant.
The crawly that did that, is most likely, out of reproducing season already..
