Yes.

I had a GFCI 20A circuit breaker in my panel feeding my pool pump motor.  I 
went to open my pool last spring and the breaker kept tripping.  So, I 
concluded that the breaker went bad.

I opened up the breaker panel to change the breaker and found that the GFCI 
breaker was infested with ants (regular ones, not fire ants), but 
interestingly, the GFCI breaker was the ONLY breaker in the entire panel that 
had ants.

Subject: [PSES] Fire ants

All,

I was wondering if anyone has any real experiences with fire ant infestation in 
electrical equipment that they would be willing to share.

http://articles.extension.org/pages/30057/ants-and-electrical-equipment

It seems to me that for high current contractors and electrical disconnects 
(not using self-wiping contacts) with contaminants between connection points 
can result in resistive connections, I^2R heating, potential arcing and if 
enough voltage is present, series arc faults which over time can erode 
connections and result in a fire.  Does anyone have experience with this as a 
real problem?

Thanks  Doug
