Muntjack deer have a habit of wandering around our group of six retirement
bungalows and munching flowers in pots, particularly Pansies. Anybody know
of any easy "buzz-off" ideas?

Muntjac and other deer are not too happy inside even normal suburban
height fenced areas where there is no easy escape, even though they can
jump quite high when they want to. Muntjac in particular tend to push
their way through gaps in the hedge, or open gates as already suggested.
We seem to be OK since I added a wire stock fence (squares of strong
wire, smaller at the bottom) inside the three rail fencing. But you have
to fence and wire all round the perimeter, however long, (as they will
wander in and across a paddock to get to your garden if necessary) and
cover all the gaps. I pushed and fixed sections of chicken wire into the
smaller gaps under the hedge.

You might also try pir lights which also stay on in twilight / early
morning.

Dogs would only provide protection if they were out in the garden at
night / in the twilight, every night.
