Slugs!
« on: June 05, 2013, 09:47 AM »
Any idea what damage they're doing?  Easiest way to get rid of them?

It depends on where they are hiding during the day.
Are they in the bottom holes of your pots or under planks that might be holding up your pots? What size are they? Slugs here in CA are large, elsewhere they're tiny, less than a quarter inch. If you're fairly sure they're not in the pots, you can bait with a dust or granule, you can also trap them by laying down damp rolled newspapers at night, they'll go in before morning when you can just pick the whole thing up, tie in plastic and discard. If their population isn't huge, hand picking at night can help. Dump them in a milk jug of soapy water so they can't crawl out. Check for their eggs which look like clear osmocote.
I've had some luck by laying down copper screen around individual pots, they recoil from the chemical reaction to their slime. Some swear by diatomaceous earth.

Slugs like to eat soft tissue like new leaves and roots.  They make molluskicides (pretty sure that's spelled wrong) specifically for them.  These chemicals dehydrate them very quickly and effectively.  "Slug Pubs" aka a shallow dish full of old beer often help but don't kill them all IMO.  Dousing your benches with salt can slow them down too.  I'd go the chemical route and it may take an internet search for something good or perhaps a trip to Lowes.  In Japan, we had bait I applied once a month to the tables.  We never saw them on the bonsai but the the day after, about 200 dead slugs would be on the benches.  Sneaky bastards.

Slugs are probably feeding on your dango cakes, also perennial accent plants such as Hostas. Iron based food traps such as Sluggo will work and be safe for pets and the environment. A bowl of your cheapest beer will also attract and drown them. Pick and smash, clean, look for eggs. They will hide on anything laying on the ground, so  i usually don't leave old pots under shelves. I catch and release Banana Slugs.

Slug bait purchased from a local garden center today during my lunch break.  Will report on its effectiveness.

Also, don't Google image search "slug bait" unless safe search is turned on.  You've been warned.

Nothing a generous dusting of DE couldn't solve.

Quick look this morning before work and it appears to have had some success.  I'm not sure of the rain will lessen the effect or not.

I read in an old International Bonsai Magazine that you have to discover their hiding places which could be under the containers. They suggest Boards could be placed on the ground around the bonsai and some of the slugs will hide out there in the daylight. Boards are lifted and slugs removed. It works but I still have minor damage. I also find eggs occasionally and remove them with tweezers.

I removed a gingko last year from a grow container to repot and found a slug that had made a space in the bottom of soil about the size of a wine cork. However, the bulb pot didn't have a screen.

Some unidentified insect chews my pyrachantha leaves on a regular basis. Last year it lasted all season in spite of using a systemic and an occasional spray of permethrin. I don't know what it is, maybe beetles?

Best,

Augustine
