Slugs and a request for your comments

For some years cutworms (larvae of a moth) infested my bulb house, where 
they pupated in the deep plunge sand. I think I've finally got rid of 
them using Bt (Bacillus thuringensis) spray on the most affected plants, 
particularly the very early-flowering Fritillaria raddeana. This 
insecticide is used against the larvae of Lepidoptera, particularly on 
plants in the cabbage family; I don't know whether it harms anything 
else. I use the iron phosphate type of slug bait in the bulb house as 
well, but not in the garden.

I happen to like snakes, and there were plenty of non-venomous ones 
where I used to live in the Oregon countryside. I sometimes found them 
when I pulled up groundcloth, where they were enjoying the moisture and 
warmth. They were preyed on mainly by large birds such as crows; I once 
watched a fascinating mid-air struggle between a crow and a small garter 
snake. My big, heavy-coated dogs didn't try to kill the snakes, but they 
liked to fall on them and roll, which annoyed the snakes. The 
distinctive ophidian scent must have been as pleasing to the dogs as a 
nice fresh pile of manure. The only problem I had with the snakes was 
that they hunted my goldfish. I once caught one slithering out of a 
shallow pond with a big goldfish in its mouth. I grabbed the snake, it 
let go, and the fish, returned to its own habitat, survived.

For one thing, they're ever more expensive and I've found nearly all the gardeners I know are wary of using a lot of them as they recognize the danger they create for our children, pets and other wildlife, not to mention themselves. Even Clorox bleach for disinfecting is something I no longer use, although if directions are followed to the letter, it's more or less safe. I might use one application of herbicide a year but if I have "bugs", I isolate the infected plants and use soap or similar natural spray.

Unfortunately not many people take the time to verify the drivel often published as "latest break through" in media. All we can do is try to continue educating ourselves.

They certainly like being able to crawl around my nursery as there are so many places where they can sun themselves and eat enough slugs to be too fat to crawl through the front door. But they sure don't like being surprised when the water hits - good for them I don't water any more than I have to. My mother used to complain about not seeing snakes anymore. She ignored me when I explained that Dad out there mowing the hillside took away their habitat.
