Plants often use this technique to get rid of some excess water. It is called
guttation and takes place (is visible) mainly in the dark under hunid
conditions. Many plants show this phenomena (ficus and monstera are two good
examples for houseplants.
It is however also possible that this is a sign of a bacterial infection. In
that case the drops are usually slighhtly brown or yellowish and a bit sticky.
If that is true try to get a new plant, it's very difficult to cure.
Don't blame it all on bugs.....
