Pesticides, chemical? organic? HELP

hey yall, i got two plants, both just recently confirmed on being females, ones around 5 1/2 feet and the other is around 4, the smaller one is getting eaten to shit by somthing,

i have liquid fence so im posotive its not rabbits or deer, so im sure its some type of insect, i recently found spittle bugs on it, but i got rid a those and havnt seen them since

so my question is, is it safe to use a chemical pesticde that can b used for a wide variety of insects in this part of the plant cycle? because i already have some types in my garage.

secondly, if the chemical pesticedes arent a good idea once the plant gets into flowering, what organic pesticides can i use to keep bugs from eatin my buds

please help

garlic oil or hot peppers work.

get some neem oil its an orgianic pesticde an fungiscide....but adding any pesticide in flowering stage is not a good idea...use some killer bugs like lady bugs an praying mantis's
