You are wasting our time.

You are not very honest person after comparing your notes before and your letter right now.

Here is the reason:
"I admit that I forgot to clean the trash bin which, as you said, brought bugs, but if you inform me that you wanted to enter my room, I could ask help from my friends or hire people to do the cleaning work."

You contaminated the unites by attracting bugs. For a leasing property termites are major problem and the housing authority and health department can shut down the property and issue heavy penalty to the landlord. It is constitute an emergency situation just like he smelled gas leak in the unit. Landlord has to take immediate action to protect your neighbor and his licenses.

You neglect mention a very important reason why the landlord entered the unit. It wasted a lot of our time.

If the landlord is reasonable on the cleaning and termite, pay it. You are going to loss.
