My raspberries and red and very sweet and now I have found thread-like worms on the fruit (about 2-4 in a bowl) when washing. What are they and how do I treat the fruits? They are black or grayish and threadlike and about 1/ to 2/3 of an inch long.

It sounds like you might have the western raspberry fruitworm, but it is hard to know for sure without a sample. This is a beetle. The adults will feed on the leaves in spring and lay eggs on the fruit. The larvae feed within the developing fruit for 5-6 weeks, and are especially noticed at harvest. The larvae, however, are whitish and only about 1/3-inch long. The larvae then drop to the ground to overwinter as pupae in the soil. Treatment is targeted at the period of egg hatch, just at pre-bloom and again post bloom, if necessary. Spinosad is an excellent, safe product to use, but carbaryl and malathion will also work.
These larvae can be washed out, as you have done, and they are also killed in the canning or freezing process.
If possible, please bring a sample of the damaged fruit as well as the larvae to your local Extension office, and they can send the sample to the Utah Plant Pest Diagnostic Lab. Or, you can visit the Web site for forms and mailing instructions: www.utahpests.usu.edu/uppdl. This way, we will be recommending the right treatment for the right pest.

- I have a house in Kanab with a lot of Desert Poppies and Blue Flax Grass that is pretty tall surrounded by Junipers in the front yard. I think I may have Noseeums. If so how do I get rid of them? I got bit up pretty bad last weekend working in the yard.
- I have been fighting a battle with snails and slugs for the past 10 years. I can't find diatomaceous earth that is free of serious pesticides and I can use around my vegetables. (It seems to be more like typical non-garden pesticide in the form I find it.) I also wonder about copper barriers and what sort of copper I could use for that.

- I live in Bloomington Just south of Saint George, Utah. About a week ago I noticed hundreds of little greenish/yellowish flying bugs. Like I said they have been here about a week and they are not going away. I have lived in the area for about six years now and have never seen them before. Do you have any idea what they are and how I can control them? Regards Randy
- We have ants inside and outside of our house. Twice a year, we have flying ants in the basement of our house. In our garden and strawberry patch, we have big aggresive ants that make it difficult to enjoy our strawberries. What is the best way to get rid of the ants in these places? Is is ok to poison them around the strawberries? What about in the house?
- I have seen small white worms crawling on the fround around my home. Can you tell me what they are? They move very very slow and are in a group as they move.
- What insects attack strawberries and what is the recommended control?
- I live at the edge of a neighborhood bordering the mountains in North Ogden. The last week we have seen hundreds and hundreds of little beetle-like bugs that have six legs, two antennas and a green/black body with a bright orange border. It appears the adult version of the beetle is about 1/4 inch long and fairly round. I'm wondering what this bug is and what damage it can/will do. I have close-up photos that I'd be more than happy to provide. Can you please help me identify this pest?
