CheapBedBugs.com and many other web sites sell healthy, living bed bugs to verified scent detection canine owners and Pest Control Professionals.
Buy 50 or 100 bedbugs, and then raise your own massive colony using this technique before releasing them "to the wild" And by "the wild" we do not mean at a Trump Hotel or at the White House. That would be wrong. Do not do that.
That said, this seems an obvious idea just waiting attention and time from a college biology student, environmental or social justice activist, or even a foreign power. Trump's own rhetoric has suggested the idea to America's cartoonists.
