I have little holes in all my hostas this year. Can you tell me what type of bug does this and what the remedy might be?
The Gardener’s Answer
When it comes to hostas, the most common pest problem is the slug. These two seem to go hand in hand and the damage of small, round holes is exactly what you have described. Slugs are nocturnal feeders, so you will not find them on your perennials during the day. Control options include diatomaceous earth and Sluggo, which are both organic products you should be able to find at your local garden center. As with any product, be certain to follow recommended application rates.
Home remedies include a shallow bowl of beer. Leave the bowl of beer out at night while the slugs are feeding and in the morning you will find the culprits and be able to dispose of them. Melons are also great and any kind will work. Place the hollowed-out part facedown in the garden. Again, do this at night and the next morning you will have a melon full of slugs. If you start a control program early next spring, you should be able to deter these slimy pests.
