Frankly speaking , those look more like worms then cater pillars
. Usually caterpillar have some hair or spikes on their body or is
completely bald but big in size . Those look more like the worms
you see in a rotten durian or fruit . If i were to be staying at
that place , i will spray baygon all ard my house and put sulphur
also . Baygon plus insecticide , to make sure none goes past my
territory and also to reduce their numbers.
