repellent question

(Houston,TX)

I am curious to know if using these home made repellents could burn or damage the plant or leaves.
I used 3 eggs, quart or so of 2% milk, cayenne pepper, water, dish soap, onion, and jalapeno pepper seeds. Mixed in gallon milk jug and letting sit for a couple days before spraying on the tree leaves and trunk.
I just don't want to damage or kill my pear, grapefruit, orange, lime, lemon and avocado trees.
