    Default Chew...chew...chew...from my orchid tree mount

    Ok, here's a good question for ya.
    I kept on hearing a chewing sound coming from my orchid tree mount. Kinda like a tiny cricket "chirp". I knew something was there 'cause I kept finding sawdust on the floor. I had a small piece of the same tree that I had stored for later use and when repotting my orchids & found the same dust. I split the piece open and found a little grub about 3/4" long eating just under the surface of the wood (wild grapewood). From what I can tell, it's a wood worm (larvae of a beetle). Does anyone have any experience killing these? I'd hate to have to unmount all my orchids and dispose of the tree because of one pest. I've been told that a 50/50% (quart) solution of 70% Isporopyl alcohol & water with about 2 tsp of 409 cleaner would do the trick. Any suggestions??? Thanks in advance!

    These borers usually have breathing holes, you can block them with horticultural wax or some water proof glue, that will also kill them.

    I try and spray my grapevine mounts with a soap solution at least once a month, if not every week, to keep the critters away. I fill a spray bottle with water and add about a tablespoon of dish soap and a teaspoon of cinnamon extract. I was thinking of starting to make it half and half water and rubbing alcohol. If you add Listerine to it, then it is also a fungicide!

    Great suggestions and all natural...I think those sometimes are the best.

    Although I will say, Listerine leaves a tacky film on the leaves that eventually washes off. Kind of annoying, but hey it's cheap! And even cheaper if you buy the huge bottle of generic brand!

    here the glue is called PVA for simple paper art& craft. Aimed a children really or for parents entertaining the children, creche nursery playgroup. White thick glue that drys clear. Doesnt last forever and could probably peel it of bit by bit. Will need mount media to be dry and glue will dry as thick clear varnish.

    Ofcourse if mounts are matured then roots would have clung deep in all crevices/ pockets making things arkwad for root maintenance.

    Alternative clear silicon for home diy leaks/ bathroom, aquarium contruction etc Smooth on and out across mount allowing to cure as the strong acetate/ acid emissions from ingredient dries/ curers.

    Both could be used to affix media deco if your feeling motivated and adventorous enough - dried reindeer mosses lichens etc. Suffocate pest and improve aesthetic cultural values all in one move!

    Many methods though most will have some element of risk i suppose. You could soak 'dunk' whole of the mount plant and all in bucket aslong as possible using variable poss solutions to aid death of beetle grub. Old tea bags, garlic and chillie recipes anything obstructive for objective. Chemicals (research first) systemics pointless and spraying pointless. Organics use sulphur, fatty acids and pyrethrins derived from our delightful chrysanthemum veteran, so worth a shot as 'contact' is only useful here.. Enclose whole mount in closed tank or closedbig bottle and suffocate the fkr with sulphur smoke bomb.

    Red hot hot hot chilli pureed in water and pour as applicable, a drench, could use a dropper for accuracy and avoiding too much contact witth parts of orchid. Dont scratch your eye at anytime if you choose to prepare and execute this method.

    abit of research in spidermite treatment control will have info you could extract for your purpose due to risk of severity with this pest. As with the careful drench application plantvitality+ product as it contains undeclared chemical despite being marketed as organic, its not organic. Grow technologies aborted this product as it drew in attention of fraud, deciept and motive to decieve consumer. The chemical was used in US but now withdrawn banned. If surface burrows are clearly open and sighted as they exit/enter, this is your key method in declaring war.

    Thanks everyone for the suggestions. I have so many ways to kill now...lol!! I ended up using a 50/50 solution if IPA & water, 1 tsp of dish soap and some extracted cinnamon oil for some good measure. The chewing has stopped (for now) and there is no more saw dust. The fungus gnats have moved out also.
