What insect eats Marigolds?

I didn't think anything ate Marigolds so I was a bit surprised to see that some bug is eating all of the leaves off. They devoured about 6 plants in a row.

What could it be? There is an overabundance of roly polys this year. I have some June bugs too but they don't seem to be as many. Whatever it is I need to kill them before they kill my Marigolds. The Marigold is a little French yellow dwarf.

Thanks,
Frank

RE: What insect eats Marigolds?

Slugs and earwigs will strip marigolds down to the stem. Both are night feeders so a check with a flashlight after nightfall will tell you which one is the culprit. Baby earwigs are hatching out right now and they can strip a whole patch of marigolds in a couple of nights. They are tiny grey bugs with an elongated body--they don't get the classic red color until grown. For slugs I suggest safers slug bait or surrounding the plants with something rough like broken egg shells. Slugs won't crawl over sharp objects and get their bellies cut up. It doesn't kill them just discourages them.
For Earwigs This bait works wonderfully well. I had a small bed full all different sizes of marigolds. I planted them and didn't get back to check them for 2 days. Almost every one was stripped. I found this recipe--can't remember where-- But I put it out in a baby food jar and the next morning it was full to the top with baby earwigs.

Bait for Earwigs.
Equal parts of soy sauce, cooking oil and (molasses or corn syrup). The molasses or syrup is bait to attract them--the oil doesn't allow them to crawl back out and the salt in the soy sauce finishes them off and makes the mixture dark so they think it is just a hole. Put it in a small container�A good use for all those detergent scoops. Cover 1/4 to 1/2 an inch of the bottom of the container with the mixture and bury it up to the brim in the soil where you have a problem with them. Prop a lid or something like a piece of wood over it so it doesn't get diluted by rain and so it is a nice dark place for them to hide for the night--ha. When you prop the lid, leave a small space for them to crawl into the container. You might have to wait a couple of days for it to work, but mine were full of them the next day. I was surprised by just how many I did get.

I didn't 'see' any slugs in my tuna cans of beer, but when I went to clean them out there were 10-12 in the bottom of each can---smallest slugs I've ever seen! Only 1/4 to 1/2" long, but they took the beer swim.

Slugs don't mind drowning in the cheapest beer you can find, and I used margarine tubs buried to their rims to hold it too, when I ran out of tuna cans.

Only issue I'm having is cleaning and refilling the tubs after the dog comes in for the night! He enjoys the beer when it's 'fresh' but doesn't go near it once it has those slimy critters in it.

Marigolds are now recovering, actually growing back foliage from their de-nuded stems.

I wonder how this 'husband's tale' about marigolds being resistant to pests came about. Slugs/snails and spider mites are probably the worst of the pests attracted to marigolds but others are, too, as mentioned above. Frank, you may have spotted your culprit....roly polies.

I had some large round tree rings that hold mulch located near the marigolds. It is where the slugs were hiding so I pulled them up and got out my salt shaker for a little payback.
