i dont understand how a tall deer .. can eat under a net ... ergo.. i am thinking small ... and i dont see the deer putting the net back after eating ... though if they were that cooperative.. perhaps i would be a bit more lenient towards them.. lol .. but i think you missed my point.. or more likely.. i didnt make myself clear ... you need to sherlock this out.. we cant tell you so you can go research it ... it is not like some wraith mysteriously hovers down to the ground and attacks ... deer.. being large.. leave cloven hoof prints in soft garden .. and a large version of what look like monster rabbit droppings .. and tend to rip and tear off the leaves ... rabbits.. well.. you saw the link ... leave no prints ... and tend to cleanly slice the leaf petiole at the ground.. and then nibble away ... they do not tend to destroy a whole plant.. and more often than not.. cut a leaf or two.. then hop away without eating them .. and that really PO's me.. as i can accept a little damage to feed mother nature.. but that is just wasteful.. whats that all about ... i presume this happened in summer.. and you probably dont have a pic to help us.. but i dont know how we get past pure speculation without some further observations from you ... BTW ... went out for a walk in my 20 degree winter up here in MI ... in a foot of snow.. i saw rabbit tracks.. and deer tracks ... and if they are here in miserable winter.. they will most likely be here.. come spring ... check out the link again ... good luck ken Here is a link that might be useful: after your walk about.. substitute 'deer' in the google search ....

I found this link that might help: Posted by gardenguru1950 SunsetZ16 (My Page) on Sat, Aug 8, 09 at 13:06 The most common "eater" of rose leaves in California is the Bristly Rose Slug, the larvae of the Rose Sawfly. The sawfly is a pudgy little wasp. It lays its eggs on the UNDERSIDES of the leaves and the caterpillars feed on the UNDERSIDES of the leaves. The rose slug is tiny, no more than 1/4-inch long and very slender, and it's the exact same pale green as the undersides of the leaves. Talk about hard to see and find! It's the critter that "skelotinizes" rose leaves. It's pretty easy to get rid of, actually. Almost any good spray will do the job: insecticidal soap, Neem, pyrethrum. The trick is to spray thoroughly UNDER the leaves. Not stand back and spray all over. You have to get UNDER the leaves. By the way, a commonly suggested spray for rose sawfly is BT. It doesn't work. It doesn't work because it's meant for the caterpillars of moths and butterflies. The rose slug is the larvae of a wasp. And I'm not sure of any beneficial insect that preys upon it. As for your rose buds, Applenut has a good idea. Go outside late at night with a flashlight. The critter most likely is an earwig, sowbug or pillbug. It also might be a slug or snail.

Personally I have never seen leaf miners do that severe damage. Normally the leaf remain intact but with white lines squiggly all over the surface. But with a major infestation I suppose it is possible. Leaf miner larvae look like tiny white grains of rice. Which is why I asked what the white collection of spots near the bottom of the photo were. In the photo it sure looks like a mess of tiny larvae. Dave

I doubt the coffee grounds are having any effect on pests. The product you used is mostly neem oil with a little pyretherin. Neem breaks down quickly and should be reapplied according to package directions. I would look at the underside of the leaves for little caterpillars. If you see caterpillars, you can squish them or use Bt. Any product you use should be sprayed on the underside of the leaves, not just on top.
