Ok, here’s another one of those home
remedies. Hang a bar of lava soap above the crotch of the trees with
borers in a pair of hose. I know, bizarre! I pooh-poohed this idea
for years but when a favorite peach tree got borers I thought, what the heck,
it will only cost me the price of a bar of soap. I don’t know why
it worked but it did. What can it hurt??
And yes the lemon scented soap gets down
in the crevices. I use a dial sprayer and the pressure helps to wash some
of them off. Someone told me that the lemon scented soap sticks to and
suffocates the aphids and thrips kind of like dormant oil.

Subject: Re: [iris-photos] Is this

Thanks for the information. I just
attended a briefing on beneficial insects. It mentioned some wasps kill
aphids. He suggested letting them say if the wasp nests aren't close
to the house. I found a wasp nest that appeared to
be inactive. Tapping, stronger tapping and then cutting the nest loose
from a bush near the window allowed me to reposition it to the back of
the yard. I was ready to flee if any wasp appeared. I don't know if
the wasps hibernate over the winter of if it was just empty.
Don't want to kill the honey bees since I
have fruit trees. I think I will try spraying irises with lemon dish
soap (Dana's advice). Now the problem is that I just bought a Bayer
product that has imidacloprid before I read the wikipedia article. I have
borers (or is it japanese beetles) that are killing my trees. They are
very bad. Apple, Peachcot, Pear have all succumbed. I am seeing it
in the other trees as well. Even the Pecan shows some signs of
investation. I had someone sprayed for years but it didn't save my
Peachcot. That was a wonderful tree and fruit. I may have to use
Bayer for the trees and soap for the irises.
P.S the below picture is from 2006.
I don't see a strong infestation this year.

should also be aware that imidacloprid is toxic to honeybees feeding on
the pollen and nectar of those plants.

and green lacewings are your best bets for biological controls that can be
purchased, but naturally occurring populations of beneficial insects are always
best, but somewhat unreliable.

Always read and follow label directions, but I have used it with great
success.

Arilbreds around them? Question is what to use to get rid of the
critters. Soapy water doesn't get into the crevices. You can buy
ladybugs. But the first thing they will do is exercise their wings and
fly away. Anybody know anyway to keep the ladybug critters in the yard?
You can buy preying mantis eggs. But they are cannibalistic and the first
ones out will fatten themselves on the siblings. I don't know how
to break apart the eggs from each other without damaging the eggs. Anyone
try green lacewings?

Anyway, I am trying to encourage the beneficial bugs.
