How does the aphid alarm work? Does it give off a chemical? I’m looking for something non toxic to control aphids.
APHID ALARM is basically the manmade version of what aphids naturally release when they are “afraid”. When aphids get scared and “alarm”, they send out a scent to the aphids of their colony to stay away. By mimicking this scent and then placing it out on the plant you’d like to protect, aphids will know to “stay away” instinctively.
We also recommend you treat any plants you’d like to protect with some PEST RID. It’s a very effective repellent made with all natural ingredients and completely organic. Treatments will last 3-4 weeks and will keep all undesirable pests like aphids, whiteflies and others off treated plants.
