how to get rid of yellowjackets without insecticides

Hi! You published in this week's Oregonian Homes and Gardens section that there is no good way to get rid of yellowjackets without pesticides- we found a way! I hope you can tell people about this idea, because it has worked very well for us and is a LOT cheaper than hiring someone to come spray toxins. You go out at night when the nest isn't active, and hang a spiral of fly paper directly above the nest entrance. When the yellowjackets come out in the morning, one or two will fly into the fly paper and get stuck. They emit alarm pheromones, which attract more yellow jackets to attack whatever might be threatening the nest. These new yellowjackets get stuck, send out more pheromones, and within a few days, most of the workers are stuck! This worked well for us with ground-nesting yellowjackets in our yard. -Christine Armer, Hillsboro

identify this shrub

I will enclose a pic of leaf very similar to those on an unknown multi trunk shrub growing here in Eagle Creek 97022. I didn't plant it, but it IS growing where I did plant a witch hazel long dead now. It is growing really fast (prob over 5' just since spring), in a wet area in sun, and don't think I want to keep it. Could be invasive??? Help!!! Thank you! Sharon

Follow up to Saturday article I’m the Oregonian - RE: yellow jackets

Regarding pesticide free treatment for yellow jackets, have you considered pouring boiling water down the nest hole (assuming that this is a ground nest)

round up

Is it a normal practice to use roundup on grain crops to time the harvest for consistancy and moisture content?

I realize this question should not have been asked in this forum. Sorry.

Using Trees to Capture Carbon

What are the best trees to grow in the foothills of the Willamette Valley to capture carbon? What are the best fruit trees for the same area?
Based on the recent research paper* that states that the cheapest
way to sequester carbon worldwide, will you and can you publish a paper/fact sheet,and other materials
that will show Oregonians top trees to plant based on area, and how many trees
we need to plant to achieve Oregon's share of the global need for reforestation? And, can you publish a paper with a plan for maximum sequestration in OR by newly planted trees? Further, if you do not have the resources to do these things, then will you ask other experts and the Governor for those resources?
Please give this your most concerted attention.

Looking for an effective pesticide that won't harm plants

I used a household/garden insect spray on our garden flowers that were getting chewed up by insects. The spray contains Pyrithrins (0.02%) and Piperonyl Butoxide0.20%). Unfortunately, it also damaged the petals of the flowers, mostly pansies. I need an effective insecticide that won't damage flowers, please. Can you recommend one? I have used something (can't remember what) that touted being a safe insecticide and caused the insects to essentially blow up. Can you tell me what that might have been? It worked great. Thanks Mike Reding
