Asian ladybugs will readily infest any home that's left unprotected and it sounds like you haven't been doing any treating just yet, correct? If so, I suggest you first read our ASIANLADYBUG CONTROL ARTICLE which explains all you need to know on how to treat and get rid of this pest. There you'll learn spraying the outside of the building is needed and what you should do immediately as they are leaving your home. Getting them now can really help so don't delay. Get some CYPERMETHRIN and spray the entire perimeter of the home making sure you get all sides from top to bottom. Next, use the PT PHANTOM if you're finding any inside. It's odorless and dries without making a wet mess.

At some point over the summer as fall approaches it would be wise to treat the attic as this is almost always  a hot spot. Based on your message, it sounds like this is the case in your home too. The screen access points are probably where you can administer the treatment and should be all you need to get a good application of the DELTAMETHRIN DUST applied using the DUSTIN MIZER or maybe even one of our electric rental models. But there is no need to rush and dust this area now as the ladybugs are surely leaving for the spring and summer and your effort won't have nearly as much of an impact like the outside spraying will at this time. However, the dusting will be needed by next fall for sure.

·         110 yr old farm house

·         2 story, white siding

·         Infestation on south side by windows

We would like to trap as many as possible so as not having to vacumn 2-3 times a day.

1.      Window traps seem like a great idea since they mostly seem to be there.

2.      But you said the lighted jar is most efficient

3.      And I read the pheromones are not always effective

4.      Cost is not so much a factor

Any input you have would be helpful. I am planning on sealing outside as much as possible.

E.M.

Use both. Since these traps differ in design and where they are typically installed,  it's usually smart to take advantage of what each does well. This will provide the best results in the long run. Remember, ladybugs won't always try to escape so WINDOW TRAPS won't work when they're content to stay inside. Additionally, the pheromone doesn't always work but that's Ok; just having the trap on the window will usually be more than enough to get them even when they aren't attracted to the scent.

Since ladybugs commonly seem to prefer one room over all others, installing LIGHTED TRAPS out in open areas of these rooms will be your best approach when trying to reduce this activity. I would say to get at least 2 so you can be sure to have decent coverage but if you're seeing the problem in all your rooms, more may be needed. Lastly, be sure to move these traps around as needed to insure any room with significant activity has a trap.

Lastly, sealing up entry points to the inside will really help. The PUR FOAM does a great job of sealing cracks and voids and is ideal for this task. Apply it with the PUR GUN and make sure all visible spaces are filled. Based on the structures age, I'm sure there are a lot of entry points so it may end up taking quite a bit of product to do the job right. But if done properly, you should be able to both keep out invasive insects like ladybugs as well reduce heat and cold losses to the outside. This means in the end, the effort, time and cost invested in doing a good foam application will be a worthwhile investment.
