I think of it as a a multiple deterrent battle.
For me, last year was a very light year for slugs/snais.
Slugs -
Can easily be dealt with by nematodes. Make your own in a lidded bucket, saves buying them.
Done that with my ground sown vegetable crops and potato crops for many years now and never seen any damage.
Snails along with slugs -
Use sunken beer/yeast traps using either a value brand (supermarket value 4x beer cans £1). I mix a teaspoon of yeast (easy bake that I use for breadmaking) with a teaspoon of sugar and a few pints of water). I do the double container method of traps as its a non messy trap that way. I use yogurt pots inside each other that have a reusable plastic lid.
Turn over grapefruit, orange, satsuma or similar skins and the next morning you will catch a few fellows underneath.
Early morning or evening with a torch. Walk around the plot with a bucket and pick them off the paths and ground if they have invaded (do not kill as you can use for nematodes). Always go out after a spell of rain as that brings them out.
Copper tape around the top edges of your pots and a criss cross on the bottom. I use the cheap rolls of copper tape from Amazon and it works as you never get the slugs sitting under the ridges of the pots or underneath the pots.
Copper tape around the outside edges of the raised beds.
Eggshells work wonders around around your seedlings.
Many say coffee Never found coffee to be much of a deterrent Myself and wary of using too much to upset the soil properties.
Check daily all the crevasses in your greenhouse frames. They do like to climb up and out the way during the day.
Also regularly check large stones, rocks or fallen tree bark that may be ornamental, but they love to cower underneath.
You will get some in your compost bins, probably all good as they work with the worms to break down the matter. I have a shingle area around the bottom of the compost bins to stop them crawling out and about. But I pick the ones around the top of the lid and that you can see in the compost and pop them into my nematode bucket.
Use pellets where they are away from reach of my cats, but have used sparingly last few years. Mainly on the lettuce or brassica beds.
I know some say otherwise, but never had any slug damage to my Spinach/Chard that grows in a raised bed and also to any type of Kale that I grow all around the plot.
Once past the seeding stage, never seen any damage to my Brussels Sprouts.
If there was any crops that I think they do not enjoy in my area, those above would be them.
