I believe I have a serious slug problem because all my seedlings are eaten almost as soon as they are half inch tall.

So I bought Sluggo Plus and scatter one teaspoon per square yard in the evening as instructed. The next morning, there was NO sluggo plus left on the soil!

That evening I scatter two teaspoon by accident, but again all sluggo plus were gone in the morning.

Now, I hesitate to do it one more time because per instruction, I shouldn't scatter more than 3 times per 30 day period, and I am only on day 2. Do I really have that many slugs? Or some other animals, like bird, eat them? And if no more sluggo go, how do I protect my seedlings?
