I am 2 months late in sending in my sympathatic consolation.
Look at the bright side George, they may leave their dropping to fertilize your soil !
Who knows, new species might spring up in the Spring , oop sorry...laughing on the matter.
My husband had a little farm in the South of Malaysia. He had some tropical fruit trees and
flowering plants. He is experimenting with the biofuel plant - Jatropha oil seeds.
Every new season, the squirrels will arrive and sink their teeth into the durians, causing them
to drop prematuredly. Initially we were very upset, we read that in order to get rid of these
pest, we need to skin one of them, burn it and throw the ashes around the trees then
it will stop them coming.. sounds very Voodooish doesn't it ? scarely..
We did not do anything but just watch...there must be something about nature.. hmmmm
We discovered that the durians that was chosen by the squirrels are the top grade.
And these little fellows, after their fills, they left two good months of undisturb fruits for us to feast on.
There are also stories of other little animals in the farms too....wild boars..they brought their family and
roll on the flower beds..
You should find out why these steers gets into your garden. If it is the fault of the farmers, they should
help you out...
