I got this new lovely hibiscus which blooms quite well but the flowers fall off the next day and so does the calyx. It doesn't inflate and form seeds.

I tried hand pollinating the stigma pads with pollen dust collected on a cotton bud but didn't work so far. Is there a technique that I need to follow, am I doing something wrong? Whats the best time to do this, after the pollen has dried or while it is still in the pollen sacs?

Also, I have noticed a few tiny microscopic red ants around the buds during early morning and late evening hours, could that affect seed formation?
