Asian Lady Beetle And Pets – All You Need To Know

If you have Asian Lady Beetles around the house, it is natural for your dog or cat to chase them. But are these bugs safe for pets? This article will give you all the info you need.

Dogs and cats are curious creatures; they are easily attracted to bright, colorful organisms, and they love to interact with them (including eating them sometimes!)

If the organism is as tiny and colorful as an Asian lady beetle, there is a high chance that your pet will try to swallow them. 

These beetles may seem harmless, but they can be dangerous for pets like dogs and cats because of the substance they emit when they are frightened. 

This article will discuss why these insects are harmful to your little pets and how you can control them from coming near your fur balls.

Do Asian Lady Beetles Harm Dogs (or Cats)?

Encounters between Asian lady beetles and dogs are rare, but when they happen, the insect is capable of hurting your dog. 

It all starts when your dog tries to swallow these beetles. They release a foul-smelling yellow liquid that is corrosive and causes chemical burns in your pet’s mouth.

If your dog or cat swallows the beetle quickly, the corrosive effects on the mouth are minimal. If it happens in front of you, make them drink water. 

This will reduce the chances of the beetle getting stuck in the food pipe and causing damage there. 

However, if there are severe burns, they must be adequately treated. Failing to do so can result in severe infections. 

Also, since these beetles are able to inflict pain through their bites, your pet can experience significant discomfort if one happens to bite them. 

If you have a dog or a cat in your house, and there are ladybugs in the garden, you must make constant efforts to keep these insects away from them.

Asian Lady Beetle Dog Symptoms

As stated above, Asian beetles can cause burns in your pet’s gastrointestinal tract; here are a few symptoms that you will notice

  • Excessive drooling
  • Mood changes, 
  • Sudden vomiting
  • Sudden changes in behavior
  • Inability to poop
  • Loss in appetite 
  • Drowsiness

If you notice any of these symptoms, immediately check your pet’s mouth for chemical burns, and take them to the nearest vet. 

Remember that these chemical burns can be nasty and can cause serious discomfort and pain to dogs or cats. 

Another thing to note is that exposure to dead beetles can trigger allergic reactions in human bodies as well. 

In the next section, we will discuss how to keep these pests away from your home.

Precautions You Can Take

It’s hard to control your dog or cat because if they see a colorful bug, they will go after it, no matter how much you train them.

Therefore, the best way to prevent such encounters is to keep the insects away from your home. Here are a few tips and tricks that can help you with that:

Run a thorough check for cracks and holes

Since these beetles enter our homes during winter to escape the cold, they use cracks and tiny holes as entry points. 

Asian Lady Beetles can enter homes through gaps as small as one-eighth of an inch wide.

Therefore spend some spend to check for such cracks and holes. If you find some, immediately seal them using silicon or acrylic material. 

Replace broken window frames and doors

Broken windows and door gaps are good entry points for these beetles. Go around your home, both inside and outside. 

Inspect the door frames, window frames, spaces between walls, wall voids, places in the attic or basement that might have an entry point, and more.

Fill it up with caulk or other strong adhesive material to keep these pests out

Hi there, we just returned form a family vacation to Orlando, FL. While at Disney World, this little lady (or fellow) landed on my daughter. The odd thing is I have not seen a ladybird beetle with this very odd coloration.while I am adept at photoshop, I assure you this is how this critter looked!!!! 1/3 orange, 1/3 golden and 1/3 cream. There were no photos on your site that I could find showing this coloration, so thought I’d see what you had to say. Perhaps it’s completely common, but I’ve not seen one like it before. Thanks!

Hi Tara,
Thank you for confessing to your knowledge of Photoshop. This bicoloration is unusual. This is a Multicolored Asian Ladybird, Harmonia axyridis. It is the species responsible for huge aggregations entering peoples’ homes in the eastern U.S. We have located a wonderful table of color variations on a British website that also calls it the Harlequin Ladybird or Halloween Ladybird. BugGuide also has many photos of this species, but none like yours. BugGuide indicates that “The only consistent marking is a strip of color along the edge of the pronotum (between the head and the wings) but the color of that strip can vary from white to red. In the east, the pronotum is usually white with four black spots, which range from small spots to large patches that may blend together to look like a black M (or W). ”

Update: November 23, 2010
We just received this comment that nicely explains the bicolor variation:  “The right elytron (forewing) probably died early, keeping its “young” orange color, while the left continued to store red pigment (caroten).

Your letter to the bugman:  Discovered a Two-Toned Asian ladybird beetle by my porch  light the other night. Believe that’s the proper ID, one mentioned on a similar photo that its possible that its its wing-case died, leaving one to be lack of red pigmentation?
Curiously, the other post was taken years ago at Disney World, so could this be possible that its genetic mutation instead?

Two-Toned Multicolored Asian Lady Beetle

Dear Alexis,
Sorry for the delay.  We were interrupted while creating a posting for your submission and it was saved as a draft and forgotten.  The Multicolored Asian Lady Beetle is quite variable.  The suspicion about the dead elytra or wing cover is interesting, but we don’t know if it is accurate.
