Bet you don't have these in your greenhouse!

There are a few novel pests associated with growing orchids in the wild in the tropics. I have coconuts by the ton here so I use the husks for mounting orchids. I keep a little pile of husks for this purpose (great for firing up the BBQ grill also). Some of the critters here like these husks too so you have to be careful when picking up a husk.

A couple of pics attached.

Readbacked Coffee Snake. Very pretty and harmless snake, but it looks a lot like a variety of coral snake found here. I don't generally exam closely enough to confirm the difference because the coral snake, although quite non-aggressive, is potentially fatal.

Black Scorpion. They look like their sting would kill you, but it is only about like a bee sting.

Ants (no pic). Another problem I have here is little black ants (not leaf cutter ants) who like to eat orchid buds and blooms...very annoying to wait for something to bloom only to have it become breakfast for ants. Any suggestions on how to keep these little guys off the blooms? Maybe some kind of non-toxic gooey substance applied around the bloom spike?
