What is bad about ladybugs?
Ladybugs have captured the hearts of many because of how they are depicted in animation pictures. They are a valuable insect to have in your garden because they are natural predators of plant-eating pests. However, just like any other animals, these little critters also have their ways on how they can protect themselves.
Are Ladybugs Poisonous?
They are not poisonous to humans. However, they have a toxic effect on some other animals, such as birds or lizards. They release a foul odor smell to warn other animals that they are poisonous.
There are more than 6,000 species of ladybugs in the world, and each of them has this capability of releasing a foul smell to protect themselves from any harm that may come their way. In this article, you will learn how ladybugs defend themselves and how their noxious smell affects humans and other animals.
How Ladybugs Protect Themselves from Harm
It is such a wonder how nature created a warning system through the ladybug’s colors. Some of the colors that warn their enemy are red, yellow, and black. And these colors are what ladybugs usually have. The colors show predators that they are about to eat something that is not pleasant to their taste pallet.
The Colors of ladybugs: Their colors can warn predators of their dangers such as being poisonous and bad tasting. The ladybug that consumed the most food during its early days tends to be the brightest color out of all of them. The more voracious the ladybug is, the better their survival rate becomes.
What will repel ladybugs? Having said this, ladybugs who ate skimpy will have an ashen body color. The better their diet gets, the more poisonous the ladybugs can be. Those ladybugs with bright colors will have less chance of falling prey to predators.
The Odor they Release: The odor that they release is similar to the smell of dead leaves. Another great advantage of their colors is its capability of camouflage. They can easily blend to bright colored flowers, thus avoid getting seen by their natural enemies.
Do ladybugs pretend to be dead? One capability that ladybugs also have is ‘playing dead.’ When they sense that a predator is on to them and they can’t handle them, all they would do is lay on their backs. They would also pull their legs up, and typically release a small amount of blood from their legs.
The Chemical they Release: The ‘blood’ that they excrete is yellow, and it smells quite awful! The term that is used for this technique is called reflex bleeding. The putrid smell of ladybugs and the apparent look of death will deter insects and animals that would want to harm them.
The chemical odor that the ladybug releases is called pyrazine. This chemical is released on the ladybug’s special glands located at their feet. Now, the same chemical is released once the prey eats the ladybug.
Dangerous to Predator: It will take a whole lot of ladybugs to kill a particular predator. However, once a specific predator tastes how bad they are, they wouldn’t dare to eat another one.
Once the threat has passed, the ladybug will continue its regular activities.
The Ladybug’s Dangers to Living Things

Ladybugs would resort to cannibalism in order to survive.
Most of the time, this happens when the adult ladybugs molt their hard shell. If the ladybugs are really hungry, it will result in eating the unhatched eggs and pupae during their search for protein.
Ladybug’s Bite (Poisonous or Not?)

Now, the biting mouthpart of a ladybug rarely has the force required to bite through human skin since they hardly bite. Having said this, the bite from the ladybug will often result in a red bump on your skin that may hurt for a few days.
Still, just like any other insects, some people may have an allergic reaction to their bites. There are also some situations where it might lead to an adverse reaction such as anaphylaxis shock. If a ladybug bites you and you see unusual swelling, it’s best to contact your physician.

- However, if you have pets at home, and they may be prone to eating the bugs, it might not be the best idea.
- Now, if the infestation is already hard to handle yourselves, contacting the nearest pest control is a great idea.
