Synthetic blood development hasn't come far enough to be suitable for transfusions but it may be good enough to attract bedbugs. You could lace the blood with Ivermectin to kill them and perhaps pheromones to attract them. The traps may need to be heated to simulate a warm blooded animal.

Or you could have heated traps and inside they could be full of excelsior, which is cheaper than artificial blood. On the outside they could be dusted with insecticide.
