|Lower leaves are nibbled, topmost leaves OK.|
Are you noticing a few nibbled holes in your lily leaves here and there? Are there slime trails on rocks, bark mulch, or has something munched a newly emerged lily sprout and you didn't see the culprit?
Do you live in the Pacific Northwest or somewhere else with copious amounts of spring/early summer rainfall?

If you have not already done so, now is the time to take measures against damage from mollusks.
Slugs especially like to feed at night, when the air, soil and grass is cool, but are not adverse to feeding during rainy days or while hiding from the sun under a canopy of low-growing plants.
These soft bodies pests come in all sizes, but the most damage seems to be the stealthy newly hatched, less than one-half inch long in length. You might not notice anything is amiss until the damage has already begun.
Control is not as difficult as it might seem.In fall, cut back Daylily plants or other dense perennials and use a garden rack or hand tool to disturb any mulch, especially large nuggets of bark, to discover any white egg clusters. Destroy them by scooping up and dropping into a bucket of soapy water or by squashing the eggs with your trowel. Crushing all the eggs can physically be more difficult, so scooping up the clusters, soil, mulch and all is probably a better plan. Clean up yard debris promptly and relocate any compost piles to an out of the way location, not just for aesthetic reasons, but also to avoid slugs laying eggs near your garden.
A flock of obliging Chickens will happily cultivate around your plants in fall, plus seek out and consume each and every slug or snail egg. When we lived in the city, our hens would always find an escape route into the back yard. There were never any slug or snail problems in the back, but since the ladies never made it around to the front of the house, there were a multitude of snails throughout the rock garden.
Some or all of the following may work for you.
- Using any brand of natural or chemical slug bait will help control their seemingly exponential growth in the garden, especially if you are quick to act in spring and remain vigilant.
- Use a barrier of copper to ring important plants. Unfortunately, pure copper is more difficult to find and is now expensive - my roll from years ago is still useable, especially if I take care to pick up the rings and store them over winter in a garden shed. Copper clad products do help, at least until the copper wears away, so storage again becomes the key to longevity.

- Beer-fest parties in the garden. Stale beer and aged, bubbly yeast-brown sugar recipes will attract the varmints to a dish and supposedly drown them when they fall in. You will need to bury the container so only the rim is exposed, giving them easy access, but with the fluid level low enough so there is no escape. Keep any beer-quaffing animals away from the dish by using an wooden box or other cover. You will then be faced with disposal that can be rather gross, so don't use anything you will ever want to use again; a cheap cottage cheese container will work just as effectively as Mom's china.
- Setting out half grapefruit, orange, melon or banana peels, cut side down, will attract slugs overnight and in the morning, you can simply scrape them onto a trowel and into a bucket of soapy water for later disposal.
Useful to a degree.
- Rough gravel, shelled nuts, Diatomaceous Earth, and other sharp-edged mulch, will in my opinion, only slow them down. Slugs excrete slime to protect their underbellies, plus they will find open access if there is any break in the barrier. Note the slug (above) on the crushed rock path?
- Sharp stick at Midnight. Take a flashlight outside after dark and go hunting. The technique is simple; "poke, scrape off and drop" the slugs into your bucket of soapy water. Of course, this is not for the squeamish and besides, you'll only be targeting the larger ones, because the smaller ones will most likely escape detection. This method appeals mostly to teenage garden helpers, where the temptation to neatly fling carcasses at each other, may defeat the purpose of a "clean" landscape the next morning. Perhaps offer a bounty?
- Several ducks allowed to enter the garden with supervision during the summer will happily consume bug, worms, slugs, snails and other tasty tidbits before moving on to a salad buffet, so keep an eye on them before they start on your plants. The resulting fertilizer can be a benefit, but not for veggies that are meant to be consumed in the near future and eaten raw, such as lettuce. Ducks are most effective in a fenced barrier between the garden and "wild areas" of grass, fallen leaves and other areas that naturally harbor mollusks. Duck poop is apparently an irresistible attractant, so slugs and snails will travel a distance for the source of this seemingly delectable food, and thus become a meal themselves. Ducks are also quieter than chickens in the garden, and may be a better option if neighbors are less than enthusiastic about hearing cackling hens. Of course, a few fresh eggs may win over even the most stubborn neighbor...
