But he certainly never expected to find himself battling to the death against the Mother of All Wasp Nests.
"I have never seen a nest this large in my entire life," Simkins told WFLA. "This is the prehistoric nest from the dinosaur ages."
An everyday nest, Simkins says, might contain anywhere between 1,000 to 5,000 insects. The Jurassic nest, by comparison, may have contained "more than a million."
Simkins set out to eliminate the six-by-eight-foot beast, only to find himself being attacked by countless worker wasps.
"I have to be honest with you, I was terrified at one point," he told the local NBC affiliate, "and there were several times that I had to pull out and get a breather. My heart rate was racing, I had hundreds of them on my veil."
Eventually, the nest was conquered, and Simkins somehow managed to walk away with only a single sting on his chin.
"We definitely did save lives," he said. "[I]f somebody comes across this, you're not going to get away. You can see in the video, I run a hundred yards away and I sill have thousands of yellow jackets chasing me, all over me, trying to kill me."
