from info I found, watermelons don't kill ants but do you have ants on watermelon plants or do you need a way to kill ants?
Watermelon attracts ants.
I need a safe way to kill ants on a wolf sanctuary
so safe for animals and the dirt they walk and live on
Those little buggers are relentless, aren't they?!? This is the most effective method and all-natural spray DIY that we use with ants. It's best indoors, but will also work outside with more frequent applications. It's even been featured on Hometalk! Hope this helps! Hugs, Holly
