Sandy, Utah area (foothill benches. I am seeing sparse (not dense threads or tent-like)spider webs spanning approx 1-2 inches in the crotches of various limbs on scrub oak (no bugs or spiders are visible, however, did recently see only one yellowish/brown spindly pointed legs/body spider on limb which was about 1/2 - 3/4 inch if legs were spread from end to end). I've never seen spider like it before and can't identify on internet or books. Any thoughts, advice, or place to reference on what and how to treat? Scrub overhangs patio and everyone is paranoid to sit under trees. This is only affecting a few trees near pation, not seen on all scrub oak on property.

Can you describe the webs in greater detail? It would be ideal to
have one of the spiders identify, but if that is not possible don't
worry about it.
Generally speaking I do not like the thought of spiders coming
down on my head either, but I do not think that these spiders will
cause you any harm. There are only 3 spiders of concern in Utah
(the Hobo, black widow, and yellow sac spider),and that doesn't
sound like any of them. You probably already know what a black
widow and a hobo look like... In terms of the yellow sac spider,
what you have described doesn't sound like their usual behavior.
Here is a picture of a yellow sac spider:
When bitten by one of these your body usually reacts the same
as if you were bitten by a mosquito. In severe cases some localized
skin necrosis might ensue. People in Utah are probably most commonly
bitten by these spiders in their home.
If you are actively looking for spiders and can't find any, then
they are likely not a problem. I would consider their webs
a benefit as they may be catching mosquitoes, gnats, etc. If you
want to do something about the webs I would recommend spraying
them out of the tree with a hose. If you do this enough it may
deter the spiders from building webs, and may drive them off
to other trees to inhabit.
Please let me know if you want more information and I will get
back to you ASAP.

- Pole bean plants are getting eaten by something, little bites all over. Now leaves are turning yellow and drying up. What do you think the problem is. They get plenty of water.
- We found (we think) a black widow spider in our home last night. It is completely black with a red hour-glass shape on its belly. We are concerned that there may be more of them in our home. I normally am opposed to using chemicals to get rid of spiders or insects, but in this case I think there is a bit of a health risk. I am particularly concerned about the safety of my children whose ages range from 9 months to 5 years. What can I do to get rid of any other black widow spiders that may be in our house, besides trying to keep corners clean, etc.?
- We have flying insects black and red. long tail laying eggs in juniper trees. What are they?
- I recently moved into a house. I noticed what I thought were little black ants didn't bother me I've delt with little black ants before. then I noticed that these little ants didn't have legs that stick out. then I noticed that they weren't ants. once in awhile I would see them when I swept the floor and occationaly I would see one or a few climbing up my wall. but now the really sad thing is they are all over in my Flour, My bags of rice and now i will have to throw it all out.

- I have tons of ants outside my house. When I am weeding I run into them. I have put down some diazion and they are still there always in the same spots. Is there anything I can use outside to get rid of them permentaly. If I don't keep the diazion granules in my cracks in my garage they are always there to. I just want them gone.
- We have flying, black bugs with orange/red spots by the eyes. They are all over our year old peach trees. Do you have any idea what they could be and how we can get rid of them?
- Is there any evidence of free run chickens significantly controlling flies from horse manure? I have neighbors who rely solely on a single hen and rooster to control flies for their two horses in a paddock, not a pasture. No other form of control is used. While chickens may, in fact control insects, I suspect the only real way to control insects (particularly flies) is to routinely (daily or weekly) police the manure and dispose of it. Is there any literature on the subject?
- Is there a beetle around Salt Lake City that looks like the big, black, fast-running roaches I remember from New Orleans?
