Have any of you found a product that yellow jackets will carry down into
their underground lair which will poison the entire hive - much like ant
bait? These are between a concrete foundation and block porch so anything
flammable is out of the question. Anything that I spray at them just ticks
them off and after the initial kill off they are livid. I tossed a
shovelful of morter mix onto the hole and then sprayed it with water a good
while after dark. By mid morning they had tunneled around it.
Tenacious little buzzers! I more than a little concerned for the grandkids
who, in spite of warnings and observation, could wander into them.
As always, TIA!
I've wiped out yellow jacket nests with about a half-gallon of Demand
CS, a long lasting, micro-encapsulated pyrethrin. I used a sprayer set
to stream mode, and filled the entry hole with the liquid from about ten
feet away. I did this at dusk, just before total darkness.
Demand CS is a professional product, and banned in some states. You'll
probably have to buy it over the web. It's relatively safe, as
insecticides go, but it's shipped in highly concentrated form, which
means it needs to be mixed carefully, with appropriate safeguards.
Here's the data page for Demand CS:
Be warned - this is *not* an instant kill product. It will take a day or
two, but you should wipe out the nest.
Real simple method, no poison. Take a clear plastic container, or glass
bowl, at night, press it into the dirt and above their hole. Make sure there
are no openings, but leave a good air space in the bowl. If you use a
plastic container, put a rock on top to weight it down. As long as the wasps
can see daylight when they exit the hole, they make no attempt to dig around
the bowl and within a week, they die
I've killed many a nest by simply inverting a glass bowl over the
entrance. They can see light through the bowl and thus dont bother to
dig around it. Within a few days there are piles of dead wasps on the
ground around the rim.
I'd try that before I'd use chemicals
I've used Methoxychlor 50WP, just toss a big pinch down the hole in the
evening and they will get it on their feet and track it into the nest
and kill the whole hive in about 24 hours. Sevin dust will also work, I
just had the methoxychlor handy; use 10% Sevin if you can find it
instead of the usual 5%.

No more bees.
Ive done the same for black ants that infested a tree out back. It only
took a few days there. Gone. All dead.
