. Exterminator was sired by McGee, who also produced
Donerail, the winner of the 1913 Kentucky Derby. At the Saratoga Paddock sale of 1916, he was bought as a yearling for $1,500 by
J. Cal Milam who trained his own horses. The big colt grew fast, reaching at two but he was awkward and coarse looking. For this reason, Milam had him
gelded.
Racing career
1917: two-year-old season
On June 30, 1917, at
Latonia Race Track in
Covington, Kentucky, Exterminator made his debut in a six-furlong maiden race that he won by three lengths. Sent to race in
Windsor, Ontario, Canada, he suffered a muscle sprain and Milam gave him time off to grow into his size, which by now was 17 hands. Still, he had earned $1,500 and a potential nomination to the Kentucky Derby.
1918: Three-year-old season
Before Exterminator could begin his third season, Milam sold him to

in his workouts. (Kilmer had purchased his colt at the same sale Milam bought his, but for $5,000.)
Kilmer did not think much of his new purchase; he called him "that truck horse" or "the goat". In workouts, Exterminator was supposed to stay behind Sun Briar merely to urge him on to greater effort, but he ran easily beside the other horse unless held back. Sun Briar had topped his juvenile division, winning five of nine starts and being named
U.S. Two-Yr-Old Champion Colt. McDaniel was impressed by Exterminator and considered him the most intelligent thoroughbred he had ever known.
As the Derby approached, Sun Briar developed
ringbone and Kilmer suddenly had no horse for the race. McDaniel urged him to enter Exterminator, but Kilmer would not hear of running "that goat" in his colors. It took

100-race start myth
Found frequently and in long-time error is the assertion that Exterminator started in 100 races. Per the research and subsequent book ''Exterminator'' (#18 in the Thoroughbred Legends series), author Eva Jolene Boyd reviewed all records of his starts and the record keeping by the ''
Daily Racing Form'' and found evidence that he only had 99 official racing starts.
In addition, the local paper in
Binghamton, New York, (where Exterminator spent his final years) noted upon his death in their front-page coverage that he had only 99 lifetime starts.
The 100th "start" was an exhibition run by Exterminator alone at
Hawthorne Race Course in
Cicero, Illinois, in September 1922. It was not for
purse money, and none of his win, place or show finishes is affected by this walkover effort in a public workout.
Retirement

Racing until the age of 9, a relatively old age for a race horse, Exterminator was called by his many fans "Old Bones" or "The Galloping Hatrack" (amongst the stable lads, he was "Old Shang"). He was retired in 1924 to a life of grass and leisure, with a succession of companion ponies, all named Peanuts, at his side.
Exterminator lived in his private barn at
Court Manor in Virginia until Kilmer's death in 1940, after which he was moved to Binghamton, New York. He died at the age of thirty on September 26, 1945, in his stall at Sun Briar Court, which has since been razed. At the time of his death, it was reported that he was buried beside several of the companion ponies (all named "Peanuts") although no markers exist today reflecting their grave. Exterminator's gravestone is in the former La France Pet Cemetery, now renamed Whispering Pines Pet Cemetery,
