In 2006, del Toro pitched The Strain as a television series, but negotiations broke down when the network president at Fox Broadcasting Company asked him to make it a comedy.[38] An agent suggested expanding the concept as a novel series instead.[39] Del Toro asked Chuck Hogan to co-write the series, explaining: "I've written short stories in Spanish and English. I've written screenplays. But I'm not good at forensic novels. I'm not good at hazmat language and that CSI-style precision. When Stoker wrote Dracula, it was very modern, a CSI sort of novel. I wanted to give The Strain a procedural feel, where everything seems real."[40] Hogan agreed after reading a page and a half of del Toro's 12-page project outline; the duo collaborated for the first year on a handshake, with no contract or publishing deal in place.[41] The first installment, The Strain, was released in 2009. It was followed by 2010's The Fall and 2011's The Night Eternal.

After the first book's publication, studios and networks began making offers for the film and television adaptation rights, but del Toro and Hogan declined, not wanting a screen version to influence the way they were writing the books. After the third book's publication, the authors talked with every cable network that had expressed interest. FX was deemed most suitable because they wanted to follow the books closely and liked the idea of The Strain as a close-ended series consisting of three to five seasons. Del Toro stated that the first two novels can be covered by one season each, while The Night Eternal may be split into two or three seasons. The author is also open to creative detours that may develop as the series goes on, possibly incorporating material cut from the books. Del Toro intends to direct as many episodes as his busy schedule allows.[39] Before the series order was announced, FX gave the writing team the go-ahead to script another ten episodes, which del Toro rewrote.[42] FX president John Landgraf has stated that the series will consist of "39–65 episodes, no less, no more", adding "What if a television show could be just the length that is optimal for that story?"[43]

Regarding the style of the show's production, del Toro stated: "Basically I'm trying to do what I do in my movies which is to show it as a reality, but as a reality that is stylized. It's not like CSI or The Wire, it's real but it feels a little stylized. But the way the camera work will be is very realistic. We want to keep the camera very documentary even if the look of the show is not. The look of the show is very designed. The style of the camera and the storytelling will be very loose. It will evolve from that feel of reality, and little by little we want to evolve into more stylish, horror feel that requires smoother camera moves, more suspense and atmosphere-driven moments so it will be a mixture. I don't think that mixture has been seen a lot on TV."[44]

FX ordered a thirteen-episode first season for the series on November 19, 2013, and announced that the series would premiere in July 2014.[2] In August 2015, del Toro and Cuse announced a five-season plan for the series after the third season renewal, Cuse said, "From the very beginning, we had really talked about the first book being the first season, the second book being the next two seasons and the third book the last two seasons". He also said that beyond the first and second seasons, which are 13 episodes each, the remaining seasons were planned to each consist of 10 episodes.[45] However, in September 2016, FX announced the series' fourth season would be its last. Cuse stated, "After finishing the writing on season three, Guillermo, Chuck and I looked at our remaining story and felt the best version could be told in one more season."[9]

Del Toro and Cuse cast the series together.[46] Stoll was cast as Eph Goodweather based on his performance in Midnight in Paris.[46] John Hurt played Abraham Setrakian in the original version of the pilot, but later dropped out.[47] The role was recast with David Bradley and his scenes were reshot with Bradley.[12] Del Toro had previously expressed interest in casting Roy Dotrice, who played Setrakian in several live-action advertisements for the first novel.[48] Kevin Durand, who appeared in Cuse's previous show Lost, was cast as Vasiliy Fet, although the character was originally created with regular del Toro collaborator Ron Perlman in mind.[46][49] Lauren Lee Smith was originally cast as Kelly Goodweather, but was ultimately replaced by Natalie Brown.[50] Del Toro wanted Doug Jones for a major role, but the actor had to decline because of scheduling conflicts; he later played the Ancient and the Master's previous incarnation.[51] Sean Astin was cast as Jim Kent because del Toro and Cuse "thought it would be funny to have the most famous sidekick of all times be a betrayer".[46] For the second season, Max Charles replaced Ben Hyland in the series regular role of Zach Goodweather.[22]

The pilot episode began principal photography on September 17, 2013, in Toronto, Ontario, Canada.[52][53] Shooting of the pilot was finished on October 31, 2013. FX ordered 13 episodes. Season one was expected to film from November 25, 2013, to April 30, 2014.[54] A full writing staff was hired to script subsequent episodes. FX reportedly committed $500,000 to creature creation.[11] Twelve swords used in the series were provided by Missoula, Montana-based bladesmith company Zombie Tools.[55] Production began for the second season in Toronto in November 2014.[56]

Ramin Djawadi is the composer of The Strain score.

The music was composed by Ramin Djawadi, who previously scored del Toro's 2013 film Pacific Rim.[57]

The original key art for the series prominently featured a worm, a vector of the vampiric virus, burrowing through a person's eye. Following complaints from members of the public, FX announced that they would replace the artwork on several of their billboards.[37]
