Redknapp has been largely frustrated in his bid to sign new players this month, with Tal Ben-Haim and Loic Remy the only two fresh faces to arrive at the west London club during the transfer window.
Although Redknapp pipped Newcastle to the signing of Remy, he lost out in his bid to sign Yann M'Vila, who moved to Rubin Kazan, and Moussa Sissoko, who looks set to move to St James' Park. The Rangers boss also sounded pessimistic about the prospect of signing targets Rolando, Peter Odemwingie, Etienne Capoue and Mohamed Diame before Thursday's 11pm deadline.
Redknapp believes a large part of the problem for QPR has been the actions of football agents, who are scrapping to get the biggest pay day possible before the window shuts.
"This transfer window, I have never seen anything like it. Every agent seems to be trying to screw each other," the QPR boss told a press conference ahead of tomorrow's game against Manchester City.
"It's like gang warfare out there - it's scary. If you're trying to get a player another agent will try to scupper that deal if he's not involved in it to try to get you to have one of his.
"It's unreal, unbelievable. They're all fighting for big money - that's the problem."
He will not partake in a last-minute tour across Europe in the coming days, however, as he refuses to get involved with agents anymore.
There was a big smile across his face when he compared the situation to the so-called Ice Cream Wars - a deadly 1980s turf war that broke out between rival gangs in Glasgow who used to sell drugs and stolen goods from inside ice cream vans.
