Do Infrared Electric Fireplaces Attract Stink Bugs?

What attracts stink bugs and other household pests and bugs to your chimney and fireplace is the heat emitted to the atmosphere. The stink bugs came to your home in two ways: 

  1. Stink bugs are attracted to your fireplace via the chimney because of the radiated heat.
  2. The sparkling light fireplace generated is also an attraction to most bugs, including the stink bugs.

Gas and Wood Burning Fireplaces Vs. Electric Fireplaces

Firstly, what is the difference between gas fireplaces, wood burning, and electric fireplaces? The significant difference between the three is the source of energy. The source of energy is gas, wood, and electricity, respectively. An electric fireplace is much more convenient than a gas and wood fireplace because they are more accessible to start via the switch and remote control. You also have control over the level of heat compared to gas and wood fireplaces. 

The electric fireplace will require the continuous use of electricity, hence more bills, the wood burning, and gas fireplace produce carbon monoxide that is poisonous, and it is not suitable for your human. It is the reason while heating appliances that generate carbon monoxide must be vented and routed to the outside (atmosphere). 

But does Infrared Electric Fireplace need venting? No, the Infrared Electric Fireplace does not produce emissions. Hence there is no need for direct venting or through the chimney as required by the standard installation by gas and wood fireplace. I will decide and go for an Infrared Electric Fireplace instead of a gas/wood fireplace. 

But will infrared electric fireplace attract stink bugs? There are research and evidence that infrared heat attracts bugs like bedbugs, beetles, and mosquitos. The study by name Tracy Leskey also showed that stink bugs are attracted to blue lights.  Some bugs and fire-loving insects also have some level of attraction to infrared.

My take is that infrared and electric fireplaces will help you keep stink bugs out of your home than chimneys and fireplaces. 

Infrared Vs. Electric Fireplace 

An infrared fireplace is a better choice for us than the electric fireplaces powered by fan-forced. The infrared will provide heat faster, cover larger areas, and save you money in terms of heating cost compared to an electric fireplace.
