d-CON

In 1950, the Wisconsin Alumni Research Foundation patented warfarin, a new chemical compound which had been in development since the 1930s. Chicago businessman Lee Ratner secured a non-exclusive licensing agreement for the product, which had been approved for use as a rodenticide. He then founded the d-CON Company to sell the new product, purchasing an initial supply from another company already distributing the compound.{{cite journal |title=America's Pied Piper |journal=Sponsor|volume=5 |number=1 |date=January 1, 1951 |pages=24–25; 44–46 |url=https://archive.org/details/sponsor51spon}} (The name "d-CON" being a reference to "decontaminate".) Within a short period of time, the product "revolutionized the art of rodent control".{{cite journal |author=Link KP |title=The discovery of dicumarol and its sequels |journal=Circulation |volume=19 |issue=1 |pages=97–107 |date=January 1, 1959 |pmid=13619027 |url=http://circ.ahajournals.org/cgi/reprint/19/1/97 |doi=10.1161/01.CIR.19.1.97 |doi-access=free}} Previously, farmers had to shoot rats one at a time or use high doses of toxic chemicals. In contrast, warfarin posed minimal risk to other animals as cumulative doses were required to achieve toxicosis, and did not cause bait shyness. d-CON was originally sold in 4-ounce packages of green powder for $2.98. When mixed with grain or ground meat the product produced six pounds of bait – enough to cover an average sized farm.

Ratner hired four men to start the d-CON Company in the Summer of 1950. On September 5, a trial run of radio advertisements costing $1,000 was purchased. For seven days, fifteen-minute infomercials ran on two radio stations – WIBW in Topeka and WLW in Cincinnati – during farm or news programs. Mail order demand created by the ads was high and the following week the ads aired thrice daily on the stations. As demand remained high, more stations were added. Print ads in farm papers followed.{{cite journal |title=Mail-order Ads Power New product Into Big Seller |journal=Printers' Ink |volume=235 |date=1951 |page=40}} By December, d-CON was spending $30,000 a week on coast-to-coast ads across 425 radio stations, and employed 60 people. According to company claims, d-CON was selling more rodent killer in a week than their nearest competitor sold in a year. A month later, the company was up to 100 non-sales employees.

To increase momentum for the new product, Ratner organized a 15-day experiment in Middleton, Wisconsin, a town with a particularly bad rat problem. On November 4, d-CON was distributed throughout the community free of charge. By November 19, the town's rat problem was under control with no traces of the rodents in the area. Similar demonstrations throughout the country occurred twice a month. Ratner secured endorsements of the U.S. Public Health Service, the U.S. Fish and Wildlife Services, and local authorities, as well as customer testimonials, all of which were featured in the company's ads. Radio advertising included segments in farm shows and sponsorship of popular general interest programs. d-CON's ad agency, Marfree Advertising, had to employ ten people to keep up with all the activity.{{cite journal |title=They Built a Better Mousetrap ...

Ratner continued the aggressive advertising campaign, turning to the relatively new medium of television.{{cite book |title=Become a Multi Millionaire in 5 Easy Lessons |author=Jules Freeman |author2=Neil D. Freeman |pages=17–19 |isbn=978-1412015790 |publisher=Trafford Publishing |year=2004}} McKesson & Robbins was contracted with for retail distribution. At the peak of its advertising spending, d-CON had ads running on 475 television and radio stations, in every farm paper in the country, and in several major newspapers. On May 1, 1951, the company ceased mail-order distribution, having placed the product in more than 40,000 drug, grocery, and hardware stores. Daytime ad buys were then expanded to support retail distribution to individual consumers. Over the first eight months of its existence, d-CON had spent approximately $1 million on advertising, generating sales of $100,000 a week. The company's rapid rise has been cited as a case study in effective mail-order advertising and called "as brilliant a record for a new product as you're likely to find anywhere, anytime."{{cite book |title=Reporting Agriculture |author=William B. Ward |date=1952 |publisher=Cornell University Press |pages=326–7}}

The success of d-CON led Ratner to expand the business, announcing plans to introduce 10 to 12 household products as subsidiaries of d-CON over the next several years. The first such product was an insecticide called Fli-Pel. Although, d-CON itself became a retail-only product, the company continued aggressive mail-order sales for several years through subsidiaries such as the Grant Tool Company, Auto Grant, M-O-Lene, and Sona. In 1954, Ratner was spending more than $1 million a year on 10-minute infomercials across 300 TV stations, making the d-CON Company the nation's largest spender on mail-order TV ads. Products marketed in this manner included cleaning supplies, cosmetics, household tools, and a "rocket ignition device" for automobiles.{{cite journal |title=The Pitchmen in the Parlor |journal=Broadcasting Telecasting |date=August 9, 1954 |page=81|url=https://archive.org/details/broadcastingtele47unse}} A 1955, eleven-week-long campaign costing $480,000 was described as the company's largest ever campaign by Alvin Eicoff, d-CON's vice president of advertising. The campaign consisted of a mix of 1 minute spots and 5 minute "special service" programs across 382 radio stations and a handful of TV stations. Simultaneous, a $180,000 mostly television campaign supported M-O-Lene Dry Cleaning products, and approximately $40,000 was being spent weekly on Grant Company mail-order products.{{cite journal|title=Grant Chemical, d-CON plan use of Radio-TV|journal=Broadcasting Telecasting|date=September 19, 1955|page=195|url=http://americanradiohistory.com/Archive-BC/BC-1955/1955-09-19-BC.pdf}}

In 1956, Ratner sold the d-CON brand for approximately $7 million to household product manufacturer Lehn & Fink, retaining the subsidiaries under the name The Grant Company.{{cite book|title=Lehigh Acres|author=Carla Ulakovic|publisher=Carla Ulakovic|year=2014|isbn=9781467112079 |chapter=Leonard Lee Ratner and Lucky Lee Ranch|pages=19–26}}{{cite book |title=Federal Communications Commission Reports|series=2|volume=5|date=1966|pages=921–6; 946–52}} In June 1966, Lehn & Fink was acquired by Sterling Drug in an all-stock merger. Subsequently, Lehn & Fink continued to operate as the household division of Sterling Drug.{{cite book|title=Federal Trade Commission Decisions|publisher=US Federal Trade Commission|volume=80|year=1972|url=https://www.ftc.gov/sites/default/files/documents/commission_decision_volumes/volume-80/ftc_volume_decision_80_january_-_june_1972pages_477-607.pdf|pages=479–480}}

In the mid-1970s, warfarin resistance began to appear in mice, which prompted a need for alternative rodenticides.{{cite journal|doi=10.1002/ps.2780110602|title=The rodenticidal activity of reserpine and related compounds|author=Adrian P. Meehan|journal=Pesticide Science|volume=11|issue=6|pages=555–561 |date=December 1980}} This led to the introduction of brodifacoum in 1975, followed by d-CON's introduction of it in the commercial market in the 1980s.{{cite web|url=http://toxnet.nlm.nih.gov/cgi-bin/sis/search/a?dbs+hsdb:@term+@DOCNO+3916|publisher=NIH|work=Toxnet|title=Brodifacoum |accessdate=April 2, 2015}} The compound works similarly to warfarin, but requires fewer doses. Additionally, it causes an unquenchable thirst, causing rats to leave the home in search of water before dying.{{cite news |url=http://www.slate.com/articles/news_and_politics/explainer/2005/01/can_mouse_poison_kill_you.html|work=Slate|title=Can Mouse Poison Kill You?|author=Brendan Koerner|date=January 27, 2005|accessdate=April 2, 2015}}

In 1994, Reckitt Benckiser (RB) bought Sterling Drug. In 2008, the Environmental Protection Agency (EPA) decided to remove second-generation anticoagulant rodenticides (such as brodifacoum) from retail store shelves, listing secondary poisoning to wildlife that feeds on rats as the primary reason for action.{{cite news|title=Changes coming to common rodent poison|agency=VIN News Service |date=October 16, 2014|author=Edie Lau|url=http://news.vin.com/VINNews.aspx?articleId=34234|accessdate=April 2, 2015}} Accidental poisoning of pets and children was also a concern (as the case of a dog named Shania, a patient of Dr. Greg Martinez, demonstrated{{cite web |last1=Martinez, DVM|first1=Greg|title=Dog Breathing Hard and Coughing Up Blood: D-con Poisoning |url=https://www.youtube.com/watch?v=nUlW5W9rPRM|publisher=Greg Martinez DVM|accessdate=February 14, 2016|location=United States |language=English|format=YouTube video|date=April 11, 2007}}), but a less serious one due to the effectiveness of Vitamin K as an antidote. The ruling, which was slated to go into effect in 2011, applied only to retail consumers, not commercial use or agriculture.

In 2011, RB initiated a legal challenge to the EPA ruling, saying alternatives were either less effective or more dangerous than brodifacoum. In 2013, the EPA passed a separate rule requiring rodent control products sold to consumers be in tamper-resistant bait stations, threatening to ban 12 d-CON products.{{cite journal|title=Maker Of Rat Poison d-CON To Pull Products |author=Britt E. Erickson|journal=Chemical & Engineering News|volume=92|issue=23|page=10 |url=http://cen.acs.org/articles/92/i23/Maker-Rat-Poison-d-CON.html|date=June 5, 2014|accessdate=April 1, 2015|doi=10.1021/cen-09223-notw6|url-access=subscription}} Early in 2014, California State Department of Pesticide Regulation ruled that anticoagulant rat poison sales would be restricted beginning on July 1, 2014. A suit was also filed to by RB to block the decision.{{cite web|url=http://www.mercurynews.com/business/ci_25461592/makers-rat-poison-d-con-sue-state|title=Makers of rat poison d-Con sue California |work=mercurynews.com |date=March 31, 2014 |accessdate=March 21, 2015}}

In June 2014, Reckitt Benckiser and the EPA came to an agreement to end legal action. RB agreed to stop manufacturing twelve products with loose pellets or powder by the end of 2014, with distribution to retailers ending no later than March 31, 2015. Retailers could continue to sell existing stock indefinitely.{{cite news |title=Rat Poison D-Con to Lose Some of Its Punch |work=Wall Street Journal|date=May 30, 2014|author=Serena Ng|author2=Alicia Mundy|url=https://www.wsj.com/articles/rat-poison-d-con-to-lose-some-of-its-punch-1401483224 |accessdate=April 2, 2015}} Eight of the twelve products contained second-generation anticoagulants (brodifacoum or difethialone), which the company agreed not to use in its replacement products.

As of 2014, d-CON is the best selling rat poison in the United States. The d-CON product line consists of traps, bait packets, and bait stations. Most products are marketed towards individual consumers for control of house mice.{{cite web|title=d-CON Products |publisher=d-CON |url=http://www.d-conproducts.com/products/ |accessdate=April 1, 2015}}

Prior to 2015, d-CON primarily used two active ingredients in the bait products. In the rat bait pellets, mouse bait pellets, place packs, and wedge baits, the active ingredient was brodifacoum, typically at 0.005% concentration.{{cite journal |url=http://www.vspn.org/Library/misc/VSPN_M01287.htm|publisher=VSPN.org|title=Small Animal Toxicoses - Rodenticides|website=Vin.com |date=April 29, 2014 |accessdate=April 2, 2015}} In contrast, earlier d-CON products that used warfarin had 0.5% concentration. In the refillable and disposable bait stations, the active ingredient was diphacinone.{{cite web |url=http://www.rbnainfo.com/productpro/ProductSearch.do?brandId=10&productLineId=1420&searchType=PL&template=1|publisher=Reckitt Benckiser|title=d-CON Bait Station|accessdate=April 2, 2015}} The use of brodifacoum was discontinued at the end of 2014 following an agreement with the EPA, and was replaced with less potent first-generation vitamin K anticoagulants such as diphacinone. As of 2019 the active ingredient in all bait stations has been changed to cholecalciferol.{{cite web |url=https://www.d-conproducts.com/faq/d-conreg-baits/#faq-3|publisher=Reckitt Benckiser|title=d-CON FAQ |accessdate=October 15, 2019}}

The initial 1950's ad pitch emphasized the following points: rats do a large amount of damage to crops each year ("$22 a year per rat"); d-CON poses minimal risk to other animals; the product is undetectable (odorless and tasteless) by rats and does not produce bait shyness; and, the product was successfully tested in Middleton, Wisconsin. Additionally, consumers were promised discretion: the product was mailed in a "plain, unmarked wrapper".

The ads, and in particular the reference to the Middleton experiment, convinced most farmers to buy only d-CON and not a cheaper warfarin competitor, according to reports by retailers who stocked multiple brands.
