I have a "night visitor" in my GH.
This freeloader has been munching on the bulbs of my Rossiogolssum, Iwangaara, Coelogyne, Dendrobiums and also the leaves as well.
I have recently repoted most plants and found nothing untoward in their potting mixes, but changed them anyway, after closely checking the new mix as I was preparing it.
I thought that this would have erradicated the problem, but not so.
For the past week all plants in the GH have been sprayed 2 to 3 times with Pest Oil which is a white oil derivative. In the morning, NEW munch marks !!!
Now after a week you think this critter would have met their maker, but obviously not.
This is ocurring on upper, middle and lower shelves, which are of a course wire mesh construction which makes it difficult for snail and slugs to traverse, I know,............ I experimented with some.
So does this then indicate a flying muncher ???? or would mice do this ?
How can this thing survive a poison that I know knocks the socks off of most creepy crawly plant munchers ?
The only avenue left I assume is to fumigate the GH. For the GH owners out there, is this an option, or would it harm the plants???
I am open to any suggestions.
And yes, I even tried my own remedy of drowning the potting mixes but nothing floated to the top.
I am at a total loss and at my wits end how to combat this marauder's nocturnal eating habits.
I can no longer show certain plants in the3 next few months because of the damage they have caused, they are no longer in pristine condition required for judging. AAAAAAHHHHHHH !
