    Default Snails and Millipedes - need Help

    I recently checked some potted dendrobiums and vandas and found these critters. obviously, they've been very busy feasting on my babies' roots. i tried the slug bait and it seems to work, however, the millipedes are increasing due to past weeks' rain. is there a specific insecticide that will kill millipedes?or something organic?

    For snails...set a couple pennies on top of the medium. When they go over them it will kill them. Or sit a small dish with been in it and they will slither over and drown in the beer. For the millipedes i'm not sure...hopefully someone that has these critters will be able to help. I'd just be a hoppin' mess if those came out of my pots. Ick!

    Hi. I struggle with the slugs and snails too. The millipedes are beneficial and I just choose to ignore them but if they start getting out of hand I try 85% Sevin. Kills ants too. If that's too harsh for you maybe a mix of finely grounded eggshells, and Epsom salt maybe a possibility. Spraying them with rubbing alcohol, maybe? I've read of orange oil diluted in water. Have you tried neem oil? Diatomaceous earth is some thing new I found out about a few days ago. It sounds promising. Check it out.

    If you are successful at eliminating the snails, I would love to know how you did it. I have tried several methods to kill them. I can knock their numbers down when I go after them, but I can never completely eliminate them.

    Millipedes, by and large, are detritivores (feed on decaying matter). If you are having a "population outbreak" then either the rains in your area have driven them to "higher ground" or your potting media has likely broken down.

    The ones that cant get the beer idea to work are the ones who use fresh beer. Beer has to be stale and pugnant to catch the attention of snails. Also, you will need to use a deep dish and bury it so that the rim of the dish is at ground level. The only other method is copper. Now, this only acts as a repellent you will still need to get rid of the ones already in your garden.

    Millipedes are as beneficial (although as unsightly) as worms to your garden. They eat decaying matter and defecate nutrients in return.

    I don't often have a problem with snails or millipedes, but the Dendrobium beetles have come out in force this past week, and that's no fun at all!

    Although they are not common here I am sure they would love the weather I cant say if any method Ive heard of works but here are a few things you could try other than catching and smushing them (which may also be fun) . I heard they don't like Canola Oil smeared on the under side of the foliage. This is also one of the first and few times I would reccomend Neem Oil. Heck if it works on the ever damaging Japanese Beetle I don't see why not.

    Excellent, thanks for the info. At the moment my control method is squashing the scumbags between my fingers and scrutinizing the new shoots of every orchid every day for their tiny little eggs. Although this method is very effective in controlling them, I only have to go away for 2-3 days and all my hard work falls to pieces. I'm definitely giving the oil treatment a go.
