Moths Everywhere

I’m sure I should know this, but can’t recall ever having this problem. I have moths EVERYWHERE all over my perennial beds. What causes this? Are they harmful? What can I do?

    What kind of moths? Tiny moths, large moths, what color? If they're coming out of the ground, that means grubs, and I noticed a lot of holes (where they emerge) in large area here where there is no grass.

    I get those tiny little brown moths every year, and those can be armyworms, so watch out for caterpillars if you have swarms of those.

    It's also the time of year for tomato hornworm, and those are larger moths that lay eggs of the leaves of plants in the solanaceae family.

    Some moths are night pollinators of specific flowers, such as hummingbird and hawk moths which pollinate Brugmansia. There are also night moths that pollinate other night-blooming flowers.

    Not all moths are bad, some are actually helpful.

    Okay I need to do some more research then. They are small and light brown. I am not growing tomatoes or brugs.

    Are they also in your lawn? If so, it's probably sod webworms.

    I’m having a hard time finding an ID . It is about a centimeter across and lands on the underside of everything but did get this picture. It is definitely eating foliage that I want to keep. I guess the real question is how can I deal with them without harming the monarch cats. Dirtygardener, I have not noticed them in the lawn.

    Moths don't eat foliage, their larvae do. Have you seen any caterpillars? Try going out at night. Some caterpillars only come out at night, and disappear during the day.

    That does look like an army worm moth. Good luck on that. We were infested this past spring with their cats. They completely decimated my planter box, then started in on my garden plants. It seemed they would eat anything. Nothing was killing them for weeks and weeks and we wound up having to treat for weeks, unfortunately with harder stuff. We started with ladybugs and wasps, moved up to the "natural" stuff and then stronger "natural" stuff.

    I'd go out daily with Clorox and spray them too just because it gave me joy to watch them die on the spot.

    This is what my planter box flowers looked like after less than 2 weeks. We did also eventually remove most of the plants, although they seemed more keen on the annuals and not so much on the perennials.

    You can see one of the cats on the underside of the leaf about mid photo.

    I had an army worm infestation one year, and I went out every day very early & picked them off and drowned them in bleach water. They're horrid! I had just a few the next year, I guess the offspring of the ones that survived, but none since (knock on wood).

    CPartist, That’s what my foliage looks like. I will head out this evening with bleach water and sevin dust

    Okay I’ve done some investigating. They are definitely sod webworms. They are not in the lawn but the garden center said they would make their way to the lawn from the beds. They recommend imadacloprid. I’d really like to avoid neonicotinoids. As they are mostly just moths that I am seeing at this point, I know the larvae will be here soon. I’d love any recommendations for what I can do now without harming the bees and monarchs.

    Things to try before the bad stuff. May not work, but you won't be any worse off than you are now. U of F recommends the nematodes as a first response, FWIW.

    I currently have small brown moths in a thick ground cover of epidendrum radicans, and yearly get them in the ferns and creeping fig on the dampest shady wall. I haven't ever worried about them, as my "lawn" is all volunteers, mostly weeds and wildflower among oak leaves - similar to my neighbors'. Should I be concerned?

    I doubt you have anything much to worry about, irma. Polycultures are always more resilient than monocultures.

    Hot soapy water works well too for drowning, and is not as toxic (or smelly) as bleach.

    Insecticidal soap is my first response. The PlanetNatural.com link above also recommends using a soil drench with soap.

    Start with the least toxic remedies, then escalate if necessary.
