Can Someone Identify Whats Eating My Dahlias?

cookie_ks(9)August 12, 2006

I am hoping that someone will be able to help me. Some type of insect is eating my dahlias. Either the edges of the leaves have turned black or the leaves are eaten off completely. Also the new growth at the tops of the plants are being eaten too. I have not seen any kind of insect although I have looked several times both on the stem and under the leaves. I have been spraying with Malathion?sp but whatever it is must love it and just keeps on eating. Out of 15 plants only one has blooms on it and it seems to be the only one this pest doesn't like to eat! Any help would be greatly appreciated. I would attach a photo but I don't see where I can do that.

Earwigs. At the first sign of problem, this pest is number one on the list.

Try this; put a short lenght of hose...about 12 to 18 inches in the vicinity of the plants. Early in the a.m. go out with a bucket of soapy water, lift the hose and tap it over the soap. See what falls out.

Earwigs is the one big reason why I never try to take dahlia inside, they are a beggar since they hide in amongs the petals.

The earwigs like it moist and munch at night, but hide during daylight hours. Trying to see them during the day is pretty well impossible.

Another method if you dont have a handy hose to destroy....roll up a newspaper section....place it in the vicinity and dampen it. In the morning, go out and collect your newspaper.

Sometimes too, just like catching slugs and snails, lay a board....about 6" wide...12" long near the plants. In the early morning, peek under it. They're fast movers so be prepared.
