Having slugs or even snails in your garden can be really detrimental to your plants. Moreover, even keeping them away is a greater hassle. Many opt for commercial slug pellets to get rid of them, but they’re not as effective, especially with the presence of rain. Slugs love moisture, so you might want to change your watering schedule. Since they are known to be active at night, switch up your watering schedule to daytime instead, so your plants have enough time to dry before night comes. You may also want to try adding coffee grounds to your soil too. According to a study, caffeine is said to be effective in killing or repelling slugs when applying to foliage or their growing medium.
