I am in Vic, Australia, temperatures over 40C in summer and often snow in
the winter. Rainfall normally over 40 inches but also drought conditions in
summer. There are 2 types of slugs. The larger - up to 3 inches we call a
leopard slug and it is a meat eater, as in eats other slugs and snails,
therefore highly prized. The smaller only grows to 1/2 inch is a light
brown color with a white underbelly. It is a voracious vegetative eater.
Even the skin off the pumpkins will be eaten if I don't move them. I have
been vigilant in removing them, not relocating but stomping or feeding to
the chooks, for many years. After a summer rain, I can spend several hours
walking the boundary of my garden, just treading on them as they swarm in
from the paddock. In the end, I just get sick of it. One old building near
my place has the same problem, but neighbours only a few hundred metres away
have no slugs at all.
cheers
