Green Lacewings

Green Lacewings are tiny little creatures. However, they are also handy. People sometimes refer to these insects as stink flies due to the foul smell they release when touching.

Insects are much more intelligent than some people give them credit for. Besides, they might be able to feel pain after all.

So, instead of exterminating insects yourself, hiring an exterminator to assess the situation and use the right techniques is better. It should keep flies from entering your premises.
