Combat bait is particularly effective due to it's patented ingredient (which is why it's more expensive). The ingredient attracts roaches to the bait, they eat it, and then - ta da! - they're sterile!!! The reason you see one and there are probably tons of others is they reproduce so rapidly and it's almost impossible to kill their eggs in the eggshells.
Combat was the first of the bait trays that really worked, and, to my mine, still the best one working, especially if you use it in conjunction with borax and/or DE.
They did something unheard of at one of the worst places for roaches in the US. The problem was in some really old dorms on a major university (which I was attending at the time). The situation there was so bad that I had a few friends who lived there who had running bets on how many minutes could go by before they saw a roach. They didn't even allow food or drinks in those dorms for that reason. The university tried every poison they could use, including borax, etc. but could never control the problem to any significant extent. They even did the students' laundry to help keep everything clean. The students were ROTC cadets and were always subject to inspections, so they kept their rooms much cleaner than most college students.
Combat bait trays were put out and 90% of the roaches were gone within a month or two. I've used it and swear by it. I grew up in Houston and we never went anywhere outside at night without shoes on because of the pop-squish factor. That was my family's euphamism for "even if you stick to the sidewalk or driveway where it's easiest to spot the roaches and you try to avoid it, you're still going to step on some of them."
Also, there's lots of different kinds of roaches and at least one kind of the large outdoor roaches that I've heard referred to as "waterbugs" and "wood roaches" will invade your house, so better safe than sorry!
The borax is good for ants, too, so I'm off to get some of it, too. It actually rained a little bit here last week and the ants are starting to swarm something awful now! That also means the roaches are going to be gearing up, too, so time for me to get some more Combat trays, too.
