So if you grow peppers and you notice they are disappearing, or have 3 sets of little bites, you may have a 3 headed dragon in your garden. Do not attempt to capture with bare hands.
The best way to lure them out would be with bowls of hot salsa at night. Once you confirm their presence in your garden there are 2 ways to handle them. The first is to stop growing peppers. The other way to grow hotter peppers in another part of the garden, away from the peppers you wish to use yourself.
