So far I'm not seeing a lot of difference. The snails are still active as it doesn't affect them or if it does it's a rare event. Apparently it's very effective against pond snails which are not a problem. I still see Arion slugs coming out of their lairs and they're feeding so they're not affected either. It says the nematodes attack the slugs in the ground which these big Arions are not. I still have to use pellets for the snails so there's not a lot of point using the Nematodes if the pellets will take care of the slugs too. So far a disappointment.
Still finding feeding slugs on areas I've covered with Nemaslug. It may be a better product on heavy clay in spring where it will be constantly wet/moist. It's not effective on my sandy soil. I'll end this thread as I'm now moving on to an electric fence .
I applied the Nemaslug 4 weeks ago in all greenhouses and over the garden. The treatment is supposed to be effective for 6 weeks +. You're not supposed to see dead and dying slugs as thy just get unwell and slink off to the dark to pop their clogs.
MrsG and myself have been removing large medium and small slugs from the inside roof of the middle greenhouse all week. Some small ones are even to be found abseiling down to the plants from the roof.
Slugs and snails are dying in the Darlingtonia house thanks to the slug pellets I have in there. I'm using both ferric phosphate and Metaldehyde because I have them both. The ferric phosphate is advertised as organic and safe for pets etc however an American article I read after purchasing would say that that is not the case and if I'm reading correctly, the killer ingredient in the pellets is not the ferric phosphate but EDTA which is not even separately listed as an ingredient.
Slug pellets or Slug bait? With the pellets (Metaldehyde) the slugs /snails send out thick trails all over the place whereas with the slug bait (ferric phosphate) they just sort of crawl away and expire. I must admit I prefer the Slug Bait because of this but believe it needs keeping away from pets and wildlife.
