Prophylactic spray=good shit.
I've had pest problems from infested used pots and foreign plants, but so far never mites... all my plants get misted with dilute neem oil at least once a day.
Cute dog. If the little dude is on frontline his chances of bringing in pests is less anyway.. and making CO2... lol! My dog eats plants though so I hope he knows they are off limits!

Very cool DIY.
