Answer 2

You could try using a few different ways of scaring them off, that would be more effective. You need to give them the idea that your farm is not safe for monkeys.
See if you can tape record their alarm calls when they are afraid, and play the calls back to them when they approach.
Monkeys are afraid of large birds of prey overhead. If you can get up in the trees a home made bird of prey sitting on a branch will scare them, it needs to have large eyes as well. Staring eyes disturb them! Move your decoy every day to a different tree so they think it is alive. Look on the internet at pictures of eagles about to tke off from a branch; they are staring straight ahead and their wings are about to unfild. Its unmistakeably hunting behaviour.
There's a childrens toy, like a toy glider but shaped like a bird. Its on a spring and the wings flap up and down in the breeze. See if you can make something like that.
Another trick is to paint large round staring eyes on a cat shape and leave that around. You could try hanging eye shapes in the trees, c.d's might work if you can get them.
Monkeys don't like anything sticky on their paws. In England we have 'anti vandal paint'. Its a paint that doesn't dry and covers you with black sticky goo when you touch it. See where the monkeys come in to your farm. They probably use the same route each time. You need to invent a wet sticky paste that you can smear on fence posts, and on cloths wrapped around tree branches - don't put this on the branch as it will damage the tree, but try used engine oil or chilli paste. Engine oil will hurt the monkeys if they try to lick it off so you might not want to use that.
Scarecrows are a great idea as long as you keep moving them. They are a stick with a stuffed cloth head, which has a face sewn on. You put tattered clothes on them that flutter in the wind. The more they move the better. The monkeys probably won't approach if they think you're standing there.
As for noise, you really need a booby trap. A load of old pots and pans that crash down when a trip wire is pulled would be effective - it really needs to be big and loud.

I easily have had various consumers try them and none had lots fulfillment with them. If this has been occurring for various weeks and the canine barks interior the direction of the correction this gadget will no longer artwork with this canine. The longer it is going on the extra the canine will replace into desensitized to the noise and the fewer efficient it will be. Many little canine are yappers. you will might desire to artwork on some habit modification education with the canine to get the wanted consequences. it is going to no longer be an elementary rapid restoration. yet one which will take time and attempt. With consistent artwork and education the canine can learn how to no longer be a yappy.

I think monkeys have a similar hearing range to us.
Any sound upsetting to monkeys would probably upset us too.

The clever little b*ggers are difficult to stop, anything that works today, will get beaten tomorrow.
A couple of dog's would work best, one by itself would probably get decoyed.
