Anybody got a remedy for slugs that can be used on a wet concrete floor? I can't find where on
earth the slugs are getting in, but I found a huge one on one of my Phrag. pots. I had a panic
attack and had to pull the slimy thing off by hand.

I wish I knew... The iron phosphate baits (sluggo) don't seem to do anything for my slugs. Metaldehyde worked pretty well, but it is pretty hard on pets and you probably can't buy it. I've tried copper strips on my bench legs, they just slime their way across. Evil little things. Need more toads.

I find them living in the pots, out of sight till night. A night time visit with a flashlight can help. If I see a slime trail I repot if I can.
Also according to the USDA a caffeine drench is said to work, even on bush snails. Caffeine capsules (Amazon or others) 800 mg/gallon. Ray may have an opinion.

There is always the ball peen hammer but that’s kinda messy and emotionally stressful.

I use copper rings around newly emerging plants in the garden. I also cover the area inside the ring with grit. The rings seem to deter slugs and snails from crossing and reduce the damage on tender, newly emerging growth but they will not stop them crossing completely or completely protect an area.

I also water my garden and greenhouse with nematode worms a couple of times each year. Again it won't stop all slugs but it does knock their numbers back.

I found that smearing a swath of “Tree Tanglefoot” around bench legs is a pretty effective barrier. It is a Vaseline-like product that was originally sold as a way to keep pigeons off city buildings, but now is sold as an insect barrier.

I suppose caffeine might be effective, but I don’t know just how effective.

Ray, here is a link to a USDA article on cafine. I don’t know how effective caffeine is either but the concept is interesting and the caffeine capsules are not expensive. My first line of defense is repot. It’s the bush snails that one can barely see that annoy me the most.

I used to have a lot of slugs but since I put the plants into high-walled trays and started watering by hand instead of spraying water everywhere I have a lot less problem with them.

There is an old technique that is similar, that's also supposed to be effective:

Items required: Beer, Chair, Hammer

1) Sit in Chair
2) Drink beer
3) Hit any slugs you see with the hammer.
This reminds me of my mom in her garden except she would drink soju and use chopsticks to pick up slugs and put them in a cup of salt water

Ray where might I find Deadline? I like the hitting with a hammer best, but I can't drink alcohol and there's not room for a chair...damn! I have tried diatomaceous earth and
the slugs just went right on through it. Is measural a sort of metaldehyde?
