I have a few house plants, one of which is called a Sansevieria trifasciata or Vipers Bow String. How do I time it each year to spray my plants with insecticides to prevent infections, rather than waiting for the plant to get an infection in the first place?
Many times, the things that you will use to kill pests will also help to prevent them. This collection of articles will give you more information on pesticides that you already likely have around the home: https://www.gardeningknowhow.com/special/organic
My snake plant has 3 shoots. On the biggest, fullest one in the center has a clump of new growth and with it at the base of the new growth it has little nubby looking roots. What does it mean and what do I need to do if anything?
This is just the nature of the plant. Every leaf, include severed leaf tips are designed to become its very own plant.
If you would like a new plant, then take a leaf and make sure to get some of the root portion at the bottom. Pot this up, and care for it as usual and it will become its own plant, eventually.
If you do not want more of these, (They can stack up on you if you let them) then leave them as they are. They will not harm the plant, nor really do anything unless they are planted, or covered in soil.

@BushDoctor Can I cut it under the root nubs and plant it that way? Or will it have to be a leaf?
Was given snake plant about 6 yrs ago. It was thriving. Had new growth come up from soil. Now leaves are drooping and shivelling. I only water once a month with 1 cup of water. Plant was in direct light in window and have had very hot summer. I have moved plant out of the direct light. Can I save this plant?
Yes, these plants will not usually tolerate bright light like this. Cut any dyeing growth back, and possibly even water maybe twice a month. They are drought tolerant, they do like to be a little moist on occasion. Definitely not wet, but slightly moist.

I have a Starfish Sansevierie with 2 "pups." How big should they be before I divide them and how do I do that? The larger bud is 2.5" high.
These things root very easily from a simple leaf tip cutting, and will not be bothered by splitting them up. You can do this at just about any time. This article will help: https://www.gardeningknowhow.com/houseplants/snake-plant/snake-plant-propagation.htm
coming up, and it's been six months. All the other plants I used cloning powder on are producing new leaves. Don't have photo. I'm using an I-pad.
A photo would really help me to see what is going on, and what it looks like near the plant. Without it, or a description of your care, I couldn't give you a good answer on this.
As long as you are providing the correct care, then it should be thriving. This article will give you more information on caring for these, so that you may finally get some more leaves: https://www.gardeningknowhow.com/houseplants/snake-plant/snake-plant-care.htm
It would help to have a photo, but this can happen do to over, or underwatering, unfortunately. These should be allowed to dry out pretty thoroughly between waterings, as they are somewhat sensitive to overwatering.
For now, this article will give you more information on their care: https://www.gardeningknowhow.com/houseplants/snake-plant/snake-plant-care.htm
Why are the leaves on Sansevieria drooping?
This is common with overwatering. The soil should be allowed to dry out very thoroughly between waterings, as these are extremely drought tolerant.
They can do this in response to a lack of light, also, but this is less common.
