09 May 2024 · 2 min read



Guess what’s red and black and leaves a red stain when squashed? That’s right, it’s the return of the Jadera bugs! As spring arrives in Florida, so do these annual visitors, emerging for their mating season.  

While their large numbers congregating on plants and lawns can be alarming, rest assured, these small bugs are harmless and only temporary visitors. Let’s delve into everything you need to know about pesky insects.

What Are Jadera Bugs? 

Jadera bugs, scientifically known as Jadera haematoloma and commonly called the golden tree bugs, measure approximately ½ inch long as adults. They mostly have a black body with reddish markings on the eyes, shoulders, and abdomen. During their nymph stage, they exhibit a more pronounced reddish coloration.  

 Do They Bite or Infest Homes? 

Despite their alarming numbers, Jadera bugs are harmless to humans and pets. They do not bite, sting, or infest homes. Their sole purpose during their brief presence is to mate and lay eggs, with a particular fondness for the seeds of golden rain trees.

What Do They Target? 

Interestingly, Jadera bugs provide a beneficial service by targeting invasive trees. As seed-eaters, they focus on the seeds of species like golden rain and chinaberry trees, preventing the proliferation of unwanted seedlings beneath them.  

When are They Active? 

The peak months for Jadera bug activity are April and May, following their period spent underground as nymphs during the winter. After completing their mating cycle, the adults will die off until the next generation emerges.  

How to Control Them 

In most cases, no control methods are needed as the presence of Jadera bugs is temporary. If they make their way indoors, simply remove them. Raking up fallen seed pods can help reduce their number before the seeds detach. Additionally, eliminating hiding spots such as piles of leaves or debris near the home is recommended. 

While they may be a nuisance for a brief period, these bugs are simply another passing insect event we encounter each spring in Florida. Their populations will quickly decline within several weeks as we transition into summer.
