Thinking of removing a yellow jacket nest yourself? Take some real care before taking on this task. Yellow jackets can be harmful to your health.
Grace M; Waterloo, Ontario asks: I have a yellow jacket nest above a soffit in the corner by a door that we use to get from the house to the pool. I have sprayed foam insecticide in the areas four times, but the next morning they are right back again. How can I get rid of these pests without removing the aluminum soffit?
Dear Grace: The most effective way to kill off a yellow jacket nest is by using pesticide dusts. You pump the dust into the entry hole of the nest with a powder duster such as those sold under the Centro Company bulb dusters name. For extra safety you can buy a Gotcha Sprayer Pro extension pole that
holds the powder duster and keeps you fifteen feet from the wasp nest. You can purchase pesticide dusts at most lawn and garden stores, but the Gotcha Sprayer Pro extension is only available on-line.
The pesticide dust coats the wasps as they leave and enter their hive and kills them in short order. But, be very careful, as yellow jackets are very aggressive. They are not very social and often sting even when you haven't threatened them. Do the work in the dark using a flashlight and wear protective clothing. Or, call a pest control professional to do the work.
The longest surviving member of the colony is the queen, but she will die in the nest in the fall. All the adult reproductive wasps will leave the nest to mate. The remaining worker wasps will slowly die out as the weather turns cooler. The nest is never re-used by the wasps. So, once all wasp activity ceases the only task you are faced with is removing the nest from the soffit so it does not attract other insects that feed on dead insects.

We moved into a home built in 58. We saw a handful of dead yellow jacket
bodies. Then one or two would pop up here or there... mostly so lethargic,
only one or two could fly. We haven't had them pop up through the
winter... but now being the first of april, we found another one that can
not fly walking around. They end up in most of the rooms of our house up
stairs and down. We haven't seen them in our attic, and don't have a crawl
space. What should we do?

Read my other articles about yellow jackets. The articles talk about
fertilized female yellow jackets and what you are experiencing.

I just had an exterminator come to treat the yellow jacket nest that is
living in the roof under the soffet. It's not a visible nest, but up
inside the soffet and tons of activity through rain or shine. The
exterminator treated with dust chemicals and like 2 hours later I went
upstairs to check my sons room where the roof area is and there's
tremendous buzzing coming from the area. I called the exterminator back
and they advised it is the nest dieing and I still see them going in and
out (a lot dead on the ground outside though) so option B they say is to
come drill a hole in wall and treat from inside. Will this work? How do I
get the nest out with all those dead hornets? I don't want it to cause
structural issues to my home...it's in my sons room! Right over his

After a treatment, the nest should be totally dead within a day or two. If
the noise persists the exterminator should return for a free retreatment.
You paid him to eliminate the nest and he should do that. Once the nest is
dead you will have to open the drywall and remove the dead nest. Don't do
this until cold weather arrives.

First of all, very nice to give your time to this site.
I had Yellow Jackets make a nest above my gutter(a shingle had blown off so
exposed the roof/the 2x4's/whatever that part of the roof is). The
exterminator used a chrysanthemums based spray this past Tuesday(now it's
Sunday). The nest really didn't seem to look very large at all, but was
hard for me to see. The exterminator did say it was rather smallish. I went
up to try to remove the nest since supposedly may attract other bugs, but
couldn't feel anything to remove and hard to see into the opening of the
"roof". Do you think the nest has already disintegrated? If not,does one
really need to remove it?

How cold does it have to get at night to start killing off yellow jackets.
I have a nest in my wall of my home. They were eating the drywall left soft
spots. I have pets and children in the home. I'm scared to death there
gonna come thur. We drilled a hole in wall and sprayed it with wasp killer.
That just seemed to make them more pissed. Our nights are down to the 50's

It's going to take several hard frosts to kill off the nest. Once dead, you
will need to open the wall and remove the nest.

I've got yellow jackets coming in a external hole in kit wall- old hs lots
of cracks & rock ext basement. Don't know how fast they work- been a wk.Got
a stethoscope, hear a few buzzes in wall but not much. Treated holes with
spray & powder then they swarmed in basement ( so bombed it) & about 30
came up wall into kitchen. I've tried to seal but it's impossible unless I
put plastic around outside of 3 windows- to trap in. Now they don't use
their hole anymore- can I get more to exit wall 7 bomb or do I have to
drill in wall?

You are doing everything wrong. Treat the entry hole with pesticide dust.
Do not use liquid sprays or aerosols. I recommend Tempo 1% dust which is
available on this website. Do not seal the hole. The wasps have to be able
to come and go. Otherwise, they will find another route that could result
in them eating through your drywall and coming into your living space.

I recently discovered yellow jackets flying in and out a corner of siding
on the front of my home. My brother in law and I dusted the holes with
Sevin powder. They were also getting into my basement i believe through the
flooring and windows, i go down there everyday and kill a bunch or find a
few bodies. After a few days of not seeing much activity I used silicone
and sealed the area outside. I am still finding them inside my home now and
a few have been found in my 3 year old daughters room as well as our
closet. should i reopen the hole outside? its been a few days, wouldn't i
want to leave it closed and let them die off by not being able to get food
from the outside world? will they build another nest inside my house??
please help before someone is stung, i can not afford an exterminator to
come in and do it.
