Kill the Queen

Monday, March 1st, 2010

As a gardener and general lover of nature, I have a hard time killing things sometimes. I have no problem ripping out invasive weeds or disease-infested plant material that is likely to do damage to the larger environment.

But, for some reason I still find myself hesitating when I encounter a pest insect. My experience could be likened to a cartoon character with a devil on one shoulder and an angel on the other, but I don’t really know which side is the good and which is the bad.

Pests Face Deadly Business in My Garden

Pests Face Deadly Business in My Garden

Let’s be clear: I really don’t like to use pesticides. It continues to bother me immensely that we have rat traps on our property, but it bothers me a lot more when we have rats invade our house, so I find dealing with them outside maintains my tolerance level. And, last year when one of my large decorative patio pots was invaded by a nest of squatting yellow jackets, I tried all sorts of techniques to get them to move on. I drown them out several times, and we even applied pesticides in a failed attempt to kill the nest. In the end we lived with them all summer despite their angry traffic raging in areas we traversed many times a day. And, yes, we did get stung a few times, and I don’t want them back.

Over the last couple weeks I’ve been doing a lot of spring cleaning in my garden and on two occasions I’ve encountered queen yellow jackets in the over-wintered duff layers in my garden. But, I haven’t killed them. And, I’m regretting my inaction now. The queens are waking up, fat and pregnant and looking for the perfect location to start a hive of their own. If we kill them now, we essentially knock out a potential summer hive. But I didn’t. I’ve got excuses like: how could I have smashed her as she sat on top of a pile of leaves in a yard waste container? But, in the end, I just let her fly away — hopefully very far away.

So, what if I see another queen? Let’s consider this post my declaration of war on yellow jacket squatters on my property. Not only is my defense for my own sting-phobic self, but it is also now to protect the population of honey bees soon arriving in my garden. The hives were delivered yesterday, and within the next two weeks the honey bees will be dropped into them. Unfortunately, yellow jackets will attack honey bees, so that’s one more reason to defend against them.

Okay, for those of you who are saying, “but yellow jackets can be good”. I agree. They can attack aphids and other soft-bodied pests. But you know what? So can lady beetles, and they don’t sting. Happily, I saw my first lady beetle of the season in my garden yesterday — just in time to tackle the aphids arriving early to a Seattle garden near you.

So, death to the queen. Pregnant or not, you better watch you you yellow-banded bitches!  I’m coming for you with a hori-hori bayonet and a honey bee mamma’s protective vengeful attitude. If you’re smart, which I know you are, you’ll move along and find another garden to inhabit this year.

Paul Tukey to Host a Special Screening of A Chemical Reaction in Seattle Area

Monday, February 8th, 2010

We hear a lot about lawns these days. I’ve reported on initiatives in Washington to remove phosphorus from lawn fertilizers. I’ve shared information suggesting that lawns may actually adding to global warming. And, of course, I’ve also offered ways to remove your lawn with minimal effort. Today, I’m excited to report that Paul Tukey, author of The Organic Lawn Care Manual and founder of Safelawns.org will be coming to the Seattle area later this month for a COOL-sponsored airing of his documentary film, A Chemical Reaction.

The trailer follows. After watching it, read on for event location and ticket purchase details.


A Chemical Reaction provides an insightful and scientific look at the various concerns mounting around lawn chemicals. It follows the studies and Supreme Court case that eventually lead to the banning of various lawn pesticides and herbicides in one town, then several municipalities and eventually the entire Provence of Quebec. (Updated Feb. 8, 2010: And, this just in: weed ‘n feed fertilizers have just been banned throughout all of Canada! Read more here.)

Paul Tukey, keynote speaker for this special event,  is uniquely qualified to speak on the subject of lawns and lawn chemical reactions. Not only has he cared for lawns for many years, but he himself succumbed to lawn chemical toxins and became seriously ill. This lead him to become an outspoken advocate for alternative lawn care programs.

Please join us later this month at Lake Washington Technical College where you will have an opportunity to meet Paul, enjoy a screening of his film,and meet with local industry to learn and discuss more with local industry professionals on this subject. All proceeds from this event will benefit safelawns.org.

When: Saturday, February, 20, 2010 from 2pm-6pm

Where: Lake Washington Technical College Auditorium in Kirkland, WA (directions here)

Tickets: $10 in advance via brownpapertickets.com here; $15 at the door

Help Michele Obama Keep Her Garden Chemical Free and Chemical-Lobby-Free Too

Sunday, April 12th, 2009

This morning I received an email informing me that the pesticide lobby is working the Obamas to add pesticides to the White House organic vegetable garden.  They may “shudder” at the thought of growing vegetables without pesticides, but I bet there are a few of us out there who shudder at the though of adding pesticides. Sure, the chemical companies pay a big role in feeding the world, but is it really necessary? I don’t think so. I know a small residential garden can be bountiful without pesticides, so why should the Obama’s residential garden have to be any different?

If you would like to read the letter from Mid America CropLife Association to the White House, go here. If you would like to sign the petition to keep the pesticides out of Michele Obama’s veggies, go here.

Knowing an Insect’s Life Cycle to Develop an IPM Strategy

Friday, March 20th, 2009

Odette from Baltimore, MD writes in:

“I have a boxelder bug infestation. I removed the box elder tree in the back last fall, hoping they would go away, however, I as welcomed to my garden today with swarms of them again. for the past 2 seasons I have been fighting these bugs with sprays, which work, but they keep coming back because I may not have gotten them all. Now that I have removed the tree, will they go away? (I moved to this house 2 years ago – the previous owner complained about them but did not know that they came from the tree. can you help me here? what else can I do? Any help is appreciated. “

Odette this is an interesting discussion item. Without a quite a bit more detail, I don’t know how helpful I can be, but here are some items to get you started.

First, I don’t know what insects you’re dealing with. It is important to fully identify the pest in order to understand how its life cycle happens and what plants it uses for these cycles. Once you identify your pest fully, you will be better armed to create an integrated pest management program (IPM) for managing the issue. And, it’s critical to be sure the insect you consider a pest isn’t actually a beneficial!

It may be that you noticed the insect in the Box Elder, but it could be that it only spends part of its lifecycle there. It may spend, say, a nymph stage on another plant in your garden or in the soil, for instance. Or, it may only live in the Box Elder. Or, it may have only spent its adult phase in the Box Elder because the Elder was under stress (pests like to go for the most stressed plant in the garden first in many cases). Or, it may need the Elder for part of its life. So, I suggest you fully identify the pest (if you haven’t already) and work with an arborists or local horticulturist to understand its lifecycle requirements. That might help you know if it will come back.

Since you do mention that you’ve been spraying, I’m going to assume you already know exactly what pest you have and that it is a pest. Knowing which pest you have is critical to knowing what course of pest management to take. If you don’t  know the pest, your sprays may have been contributing to the problem. Sometimes pesticides are applied by the unknowing only to end up killing the beneficials that prey upon our pests. Once the beneficials are removed, the pests have that much more success overtaking our gardens.

One thing you don’t mention is any damage the pests did to the plant. Did they actually do anything to the tree or garden? Or did they just seem annoying in big buzzing swarms? Could it be that these were actually beneficial insects that might have been “swarming the tree” to attack another pest that you didn’t see? It’s a question to consider…

So, what to do?

Try to identify the insect, understand its lifecycle and preferred habitats during the life cycles. If you’re unable to do this yourself, try working with your local Master Gardener Extension office to start.

Thanks for writing in and keep having fun in the garden!
