Mondo,
You know what i suggest when Mom's and Dad's get in the way of your hobby? Educate them.
First, get on the internet and identify what you have, if the 'little mites' are red, they are spider mites, if not, look until you find out what they are... use a magnifying glass. Nepenthes Gracillis (The person not the plant) seems to be pretty up on his bugs, and he might be able to help you out.
OK, armed with info on this bug, and how it will effect your plants, present this info in a paper to your parents. Yes, I said a paper... it doesn't have to be long, like a page or so, put notation in your teachers would be proud of.
Your paper should:
1. Outline the species of pest
2. Identify Control Methods
3. State clearly WHY these pests need to be controlled
After the effort you put into that, I am pretty sure your parents will help you eliminate the pests, if for no other reason than the effort you put into the paper, it shows the plants are a part of your education...
And NO... I AM NOT A NERD!
