Question
QUESTION: What repellent can be used safely on newly planted Arboricola Plants(varigated and plain green) and Agapanthus(Blue Storm)to keep an unidentified animal/rodent from eating all the leaves and just leaving the stem.Also nibbling at a snowbush plant. It is also leaving which appears to be fecal droppings(black like soil) sprayed all over the plants especially the Arboricola. I tried washing it off with water from hose but some came off and rest still stuck to plant. Also finding fecal droppings about 1-2" long on top of mulch near plant. Also observed "clusters"(size of a meatball)of soil looking droppings around some of the plants. Steve, garden is in Florida,U.S.. Desperate for answer as we are constantly up at night trying to catch this rodent/animal. Been advised that it could be deer and also to use Plantskydde. Do you have and idea what rodent/animal is eating plants? Also, do you advice Plantskydde, as it is natural and w/guarantee. Need some sleep!!!!

ANSWER: Unfortunately, you have provided conflicting information and it lacks sufficient detail for me to identify the culprit. Identification comes first.
Deer damage is very easy to note as they tear branches and leaves as they browse. They are also heavy enough to leave tracks.
I suggest you visithttp://www.icwdm.org/Inspection/Default.aspx   read the information carefully as it provides ideas on how to identify damage and to describe it so that we can id the culprit.

You may be able to id it yourself. If so then if it is a vertebrate then we have information there on how to control it. Be sure to follow all state and federal laws.

QUESTION: Sir, may I ask what was the conflicting information that I provided?   The flower bed of plants is located in the front of a bay window of our home in the front of the house.There are no trees or bushes near the flower bed other than 2 palm tress that are about 15-20 high that shade the flower bed after about 2:00 in the afternoon. No tracks are being made,as the cypress mulch is not disturbed at all each night. It is arranged all around the plants in the "bed." Although, it is evident that the animal is tracking over the Aagapanathus plants as many of the flowering stems are broken each morning and the   base of the plant is being torn from the soil. These plants have been put in the front of the flower bed as a border plant. Arboricola's are behind the Agapanthus in rows up to the bay window.   We found this morning a very solid round hard ball of black debris on top of the mulch, near our Laropatellem plant by our front door, which showed evidence of half eaten leaves. Unfortunately, it seems without a camera rolling all night long, we probably will not be able to identify this critter or critters. Sadly,  it has destroyed almost #300 in plants in the last week! I hope this somewhat clarifies the information originally provided.

Answer
Information is conflicting from my point of view, which means that you could very well be dealing with two different culprits, perhaps insect and a vertebrate.
However. as I noted before, I need many more details. Round ball tells me nothing about size. If you visited the site, you would have text and images that describe various feces and informaiton on how to describe feces to others.
