I've got small little bugs on one side of my house that look like kudzu beetles. They're not ladybugs or roaches but they're kind of round and there lots of them. like hundreds. What can I spray to keep them off the house?
Common little brown bugs that may invade a home for the winter include stinkbugs, roaches and ladybugs. You said you're sure these aren't ladybugs so my guess is they might be brown stinkbugs. If possible, please send us some for positive ID. There are reports of a relatively new beetle in Georgia called the Bean Plataspid. (scientific name is Megacopta cribraria). Native to India and China, this beetle is small and thrives on kudzu but can also live on just about any plant commonly found in the yard or garden. As you know, we have a kudzu problem in Georgia so these could be the beetles you have been seeing. We're currently trying to identify any regions with activity of this species so please call us at 1.800.877.7290 if you think the following pest looks like the one you've been seeing. For now these are the only images we have and would appreciate more if you are able to provide some.
Since these pests reportedly overwinter or hibernate when it gets cold, they could be seeking safe harborage for the upcoming winter on your home. However, they have been known to accumulate on homes anytime between spring and fall. When found during the spring, it is thought they are leaving the home for the upcoming warm months. When seen during the summer on the home, it is thought they are using the home as a nest site. And when found on the home in the fall, it is thought they are gathering to use the home for safe harborage for the duration of winter. The following video shows what they commonly do once they start invading the home:
To keep them off the house, treat the siding of the home with CYPERMETHRIN. It work's fast and should knock out the activity immediately. And if this pest is like most others, it will find the residual Cypermethrin to be highly repellent which should keep them away and off the home for several weeks. Retreat as needed which could be a couple of times a month if they reappear. This could be needed anytime from March through November. As you know, we can have mild falls well into December and my guess is they could remain active till the end of the year but we just don't have enough information to know for sure. We also offer an organic option known as BUG PATROL. Labeled for use in the yard for plants and turf, it comes packaged in a handy "ready to spray" container so you only need to hook it to your garden hose and get to work with no mixing required. Bug Patrol isn't as strong as the Cypermethrin so expect to treat more frequently if you choose this product. Lastly, if you're finding them in your vegetable garden, go with the organic MULTI PURPOSE INSECT KILLER. It's safe enough to use daily if needed but in general, 1-2 treatments will take care of most any problem.
If you start seeing inside the home, treat with CYKICK AEROSOL. This low odor aerosol is excellent for use in the house and covers a wide range of pests. It comes equipped with a crack and crevice straw tip making it ideally suited for treating all the small spaces this little brown beetle likes to use. Direct treatments to baseboard molding, door frames and around windows where they may be entering. Again, retreat as needed which may be 1-2 a month until the invasion subsides. The organic alternative for inside would be FLYING INSECT KILLER which is another aerosol that's well suited for indoor applications. Like the Cykick, it will handle this beetle when sprayed but it differs in that it leaves no real residual so you'll need to use it a lot more frequently compared to Cykick.
