pest control

Is there any DIY bug and pest control i can use for my plants? i mean some home made stuff with things u usually have at home

Actually ya, I wouldn't mind finding out my self.

Some kinda bio-degradable dishsoap

Lots of pest control products registered as "Eco friendly" contain citrus oils (Lemon, orange, etc.) usually derived from the rinds of those fruits. I don't know of any recipes off the top of my head but I'd bet a quick google search might yield some results.

Also you can look into Neem oil and any store bought products labeled as safe for edible plants, vegetables,and fruits.
