True, true...those are tricky little devils... I havent seen one nor wish to see, to be honest, but i have done reshearces on this topic and red so many books...the lore says that indeed those are beautiful..but can do damage you can only imagine... be careful...
I don't think you need to worry too much about the fae, you're unlikely to attract anything overly powerful, probably just the minor ones that live among nature. All the same, it's still a good idea to have some kind of protection spell around. I have a ward against negative energy around my house that works just fine (no I don't have a spell for it).
They are attracted to thyme plants. I found this out the hard way. I love thyme and had a pot on my balcony. Things began disappearing and I would find tiny shells on my floor! I don't live near a beach so goodness knows where they came from. I looked it up and sure enough, little air fae like thyme.
So I began setting out honey and little sweets. Even just a small bit of chocolate (like a hershey's kiss) and things like glass stones that glimmer in the light. It worked because I don't have any trouble with them, and they're protective little things! During Beltaine, I invited them to the dinner (just outloud announced it) and my mother in law was throwing insults at me unknowing of our invisible guests. Let's just say she had the most unlucky day ever! She was tripping and dropping things constantly. She burnt herself on the stove and set fire to a towel! Nothing serious, but hilareous! I was laughing so hard!
As long as you are nice to them, they're fun to have around, especially if you have mean mother in laws! =p
depending on what type of fae your trying to attract depends on what you use. You can leve treats of honey and milk and other sweets and offerings.
Sylphs like most fea, like all types of wild flowers, Djinn like firey things, but can be extreamly dangerus, Nymphs like clean and moveing water, Gnomes like dirt, herbs, and crystals. When dealing with fae use cation and some form of protection.
