I think the hardness of mac shells are overrated. They are definitely hard, but rodents can rip into them.

jackslo,
what kind of trap did you use? We once had many tree rats on our Pomegranate and I only got one rat with the generic wooden snap bar trap. After that, not a single trap triggering. I ended up hiding under the tree with a lazer pointer light attached to the Daisy pelet air gun -- I hit about 15 of them and my eyes were blinded by the full moon from wide opened iris at night.

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.

Hi, Jackslo, please contact me by mail: marcos@ovejafm.com, thanks

only losers enjoy killing animals. disgusting.

I think a loser is something a person must identify as to actually be one xD

Yes, squirrels will eat macadamia nuts. They are a favorite of the squirrels, and they can find them in nature or in bird feeders.
