United Kingdom 
We have two plant pots that keep getting the flowers and tops "snipped" or eaten. First we had geraniums in there & we noticed ant nests under them. Removed all the soil, the nests, cleaned out pots & replanted Inpatiens in there. I also placed slug pellets around the top.
Three weeks later the same has happened again.
Can you please tell me what is causing this & how we prevent it.
Thanks

You will have to get up very early & watch! Or set up a camera.

Muntjac deer? Rabbits, possibly?
