Thank you, Lynn, for being so gracious about me butting in.
You have brought up an excellent point regarding the application rate. I have to wonder if people over-apply it because of the delay between ingestion and actual death (??).
Although Sluggo appears to be more expensive pound per pound than the metaldahyde-based baits, I find it to be more economical to use as it really holds up well under irrigation (So Cal is the land of sprinkler systems)
Years ago when the only option was the toxic stuff, I would have to re-apply snail bait every 2-3 weeks as the original stuff would melt away rapidly. With Sluggo, I have to re-apply every 2 1/2 to 3 months instead so it really works out to be much cheaper in the long run, too.
