I'd love to shoot them, but nights here in the summer are in the low 50s or middle 40s, too cold. I have a nice .22 caliber air rifle. I use rat traps, on an 8 ft 2X2 to hang in the macadamia trees. I can put the trap up in the tree for the rat. The best bait is macadamia nut. The nut is drilled to stick on the trap's trigger. I had to encircle the trap-on-a-stick with wire mesh as I caught a couple of bluejays. No more birds, rats go in top or bottom of the cylinder of hardware cloth (usually the top where the trigger on the trap is). The end of last year and this year I only get small young rats, except now and then a big male. They are coming from neighbors. I have over 50 mature macadamias, always nuts around on the trees. They never bother other fruits except avocados, maybe citrus now and then.

dang, answered my own question by googling macadamia tree flowers.... this is a mystery tree still :)

I had Macadamia in my great room and hallways in a previous home. I think it's a terrific color but would never put it in a little girl's room. Not at all a color that would go with pink or purple. What about a pale green?

Haha - no. I have no room for another tree in my yard, unfortunately - or maybe fortunately? And I would guess it was about 7-8 years, if not more, before it fruited. FWIW, I was just discussing with hubby that I seem to recall I paid only $5 for the seedling at Green Thumb Festival.
