Raymond CloydGUEST
Yeah, this is the time of year where a number of different insects and mites are active or creating problems.

Raymond CloydGUEST
And if you go out and look at your sycamores, your oak trees, even your eggplants, and notice this bronzing, browning look on the leaf underside, and you'll see these Black nymphs, or the adults who are lacy-looking, hence their common name, and they are sucking insects, but they feed differently from aphids and wireflies.

Raymond CloydGUEST
They're more likely to feed like two-spotted spider mite feeding the chlorophyll, but they can cause damage.

Raymond CloydGUEST
It's mostly noticeable, especially in large trees, so we don't really recommend to do anything.

Raymond CloydGUEST
because some beneficial insects such as green lacewings will actually feed on them.

Jeff WickmanHOST
Raymond, where do we stand on bagworm activity right now? We're really beyond the spraying point?

Raymond CloydGUEST
Yeah, Jeff, at this point, the usual products we recommend are like spinosad or BTK, which is the Bacillus thuringiensis curistachy bacteria.

Raymond CloydGUEST
Those are really going to be not effective because the caterpillars in the bags are getting larger and they're less susceptible to those materials.

Raymond CloydGUEST
The caterpillars will start forming a cap on the bag and thinking about reproduction.

Raymond CloydGUEST
So if you still see bagworms on there, you can apply a pyrethroid like a bifenthrin or cyfluthrin.

Raymond CloydGUEST
But be aware that those materials are very harmful to beneficial insects and mites, as well as pollinators like honeybees.

Jeff WickmanHOST
Raymond, where do we stand on bagworm activity right now? We're really beyond the spraying point?

Raymond CloydGUEST
Yeah, Jeff, I, at this point, the usual products we recommend are around like, uh, spinosad or Btk, which is the Bacillus thuringiensis kurstaki bacteria.

Raymond CloydGUEST
Those are really gonna be not effective because the caterpillars in the bags are getting larger, and they're less susceptible to those materials.

Raymond CloydGUEST
So right now, uh, we're getting close where the caterpillars will start, uh, forming a cap on the bag and thinking about reproduction.

Raymond CloydGUEST
So if you still see bagworms on there, you can apply a pyrethroid, like a bifenthrin or cyfluthrin, but be aware that those materials are very harmful to beneficial insects and mites as well as pollinators like honeybees, so you don't wanna spray your plants.

Raymond CloydGUEST
Now, conifers we don't worry about, but if, if you get bagworms like on a crabapple tree or something, you don't wanna spray when the bees are active, so do it in the early morning or late in the evening, and thorough coverage is critical.

Raymond CloydGUEST
Those products are contact, so if they're not coming out of the bag, you're not gonna get contact on them.

Raymond CloydGUEST
When they're about a quarter inch to an eighth of an inch, which some areas they are, Then they're more susceptible to the spray applications we commonly recommend, like BTK, which is known as Bacillus thuringiensis curastachy.

Raymond CloydGUEST
And then the other one is Spinosad, commonly in Captain Jack's dead bug brew.

Zach HeftyHOST
What are some things that you talk about for controlling them, but also being safe to some of the beneficial bugs that you don't want to control, like butterflies or bees that might be pollinating your flowers?

Raymond CloydGUEST
Well, yeah, basically the strategies for turf grass management of pests The first one is keep your turfgrass as healthy as possible with proper fertility, watering, have a well-established root mass so even if you do get some insects to feed on the roots, there's a large root mass that could compensate for that.

Raymond CloydGUEST
The ones that feed on the surface like the caterpillars and chinch bugs and then the bluegrass bill bugs or the other bill bugs we have that will feed below, they're a little more challenging to do with cultural practices.

Raymond CloydGUEST
But of course, number one is provide your turfgrass, give it a deep and frequent watering so the grass is down, the roots are down below.

Raymond CloydGUEST
And of course, a turfgrass is sort of a biological desert for most pollinators.

Zach HeftyHOST
So there's a bunch of different strategies for controlling these different pests, but as you're going throughout the summer, early in the spring, middle of the summer, and then getting into fall, what are the different complexes of which insects that you'll be seeing or kind of their life cycle of when you might be seeing them out in your lawn?

And so

Raymond CloydGUEST
So anyway, but what I want to talk about is bagworms, and we're going to cover it in very detail, give you a background, life cycle, behavior damage, how to deal with them, and questions and discussion.

Raymond CloydGUEST
That's a no-brainer, okay? So bagworms, and I don't like the worm because caterpillars are not worms, they should be called bag caterpillars, but that's what happens when you get English language.

Raymond CloydGUEST
This is on the far right is Mimosa, far left is Mimosa webworm, Genestic caterpillar on the center, Fall webworm, and then Yellow-necked caterpillar, Red-budded leaf folder, and the Eastern tent caterpillar.

So are bad wounds more widely spread now or is there a natural boundary like really harsh cold winters keep the population more to the southern half?

Jeff WickmanHOST
In terms of ticks, I know there's a variety of ticks and we are seeing some ticks.

Raymond CloydGUEST
April through November is typically the period of tick activity, especially with some of the unmanaged areas, people getting out, walking around, taking walks.

Raymond CloydGUEST
We do have the black-legged and deer tick, which is the vector of the Lyme disease.

Raymond CloydGUEST
And of course, Lone Star tick is the vector of the alpha-gal, or what we call the alpha-gal syndrome.

Raymond CloydGUEST
And that's where you have these allergies to meat, and it's becoming more prevalent.

Raymond CloydGUEST
Ticks are going to potentially be an issue because with the unmanaged vegetation, things coming out, and this April through November is, I would say, typically the tick season, people need to be aware of ticks.

Raymond CloydGUEST
A couple of pointers is if you're going to be going outside more as the weather warms up, And you stay on the trails.

Raymond CloydGUEST
Don't wander off into unmanaged areas because that's where ticks are most likely to be there.

Jeff WickmanHOST
Raymond, we're not seeing a lot of activity just yet, but there are some things that maybe we should be on the lookout for.

Raymond CloydGUEST
Yeah, Jeff, what we're seeing now in this early spring is reproductive or swarming reproductive ants and termites.

Raymond CloydGUEST
They see these winged termites or ants, and they start thinking, oh, my gosh, you might have an infestation.

Raymond CloydGUEST
Well, that's just a natural evolutionary process, and most of them will die anyway.

Raymond CloydGUEST
But what's going to happen is they're going to fly, the queen will mate with the males, find a place to establish a nest, and then that starts the colonies for the next generation, okay, or this coming generation.

Jeff WickmanHOST
In terms of other insects that we might see, what else might be an early arrival?

Raymond CloydGUEST
I know there's concern in the livestock industry because certain blister beetles, they give off a chemical called cantharidin.

Raymond CloydGUEST
And if they get into hay or forage that the horses or cattle are feeding upon, it can make them sick.

Raymond CloydGUEST
The publications that I developed this year are related to the three-striped, the three-lined blister beetle and the ash-gray blister beetle.

Raymond CloydGUEST
The ash-gray feeds on eggplant and the three-striped, the three-lined feeds on chard.

Jeff WickmanHOST
Raymond, we're at that time of year when the nuisance pests are starting to make their way from outside to inside.

Raymond CloydGUEST
Yeah, Jeff, as the temperature gets cooler, we're getting into the 30s and 40s, we have a series of insects and mite pests, more of a nuisance pest, not mostly a pest of humans or plants that are going to decide to come in the house in overwinter.

Raymond CloydGUEST
That includes the Asian ladybird beetle, which I know many are familiar with.

Raymond CloydGUEST
It comes inside, congregates on the south side of the windows and stays there until spring.

Raymond CloydGUEST
They're active, but there are others like the box elder bug, the elm leaf beetle, cluster flies, clover mites, they'll be moving in.

Raymond CloydGUEST
What can you do? Well, the first thing you should probably do is caulk any cracks and crevices on the south side of the foundation.

Raymond CloydGUEST
The fall webworm, very similar to mimosa webworm, they create these webs in the trees.

Raymond CloydGUEST
And if you drive the back roads of Kansas, you'll see them on walnuts and pecans and hickory and those type of trees.

Raymond CloydGUEST
And eventually the trees are going to lose leaves, deciduous ones, and allocate resources down to the growth into storage roots.

Jeff WickmanHOST
And just because we're into fall doesn't mean that we might not see some mosquitoes still.
