When Bugs Cause Bugs: What Diseases Do Pests Bring?

AGJ Pest Management

Aside from being nuisance, bugs bring numerous diseases. Many of these diseases can be lethal. Pest control is essential, along with knowledge of the diseases. Inform yourself today and learn about some of these common issues with the following guide.

Implications of a Warm Climate

Firstly, it’s important to note that as a result of climate change, the weather is heating, and this has major implications for pests. A warm climate means pest populations in Brisbane are growing and spreading. Climate change is increasing the distribution range of many pests, like termites and cockroaches. Not only this, but some pests seem to be getting bigger and stronger and have developed resistance to many traditional forms of pest control.

Are Bugs and Insects the Same Thing?

You might be surprised to learn that all bugs are insects but not all insects are bugs. The difference is in their anatomy. For example, bugs have a straw-like mouth called a stylet.

Insects are distinguished by three-part bodies, usually two pairs of wings, and three pairs of legs. These differences are not always easy to tell by the human eye. Then again, most people don’t like to get close to these tiny creatures. It’s best to leave it to the experts.
