I don't think you have much to worry about. I did use some glue traps with a carrot or dog food to catch some loose lobsters I had, but I was never concerned they would cause me problems. Actually for the one or two lobster I caught there was tons of crickets stuck on them. Of the hundreds of roach species these are not listed as PESTS for a reason. A few escapees are not going to infest your home. With that being said lets do a little review for anybody wanting to read my opinions. I have had reptiles for over half of my life. I have owned over 100 species of snakes, lizards, turtles, and spiders. In this time I have also bred crickets, mealworms, roaches, mice, rats, rabbits, and hamsters as feeders. I still feel that the roaches have been and will continue to be the best food source for my bug eating reptiles. No they are not the perfect feeder, but they are close. There are some things you should know before purchasing them. I will give my personal OPINION and rate the species I have.
Lobsters (Nauphoeta cinerea)
This is a small roach that grow to about the same size as an adult cricket. They can climb glass and just about anything else. There are a few products like bug stop or the traditional vaseline that they cannot climb passed. They are a very fast roach and unless handled very well will escape. They are probably one of the fastest breeding feeder roaches. A colony a few hundred with the proper conditions will explode into the thousands which makes them an attractive feeder bug for people who buy lots of crickets. I would recommend feeding these using snips so they are not running around in your reptiles cage. Personally this roach helped me greatly. Last year when I was hatching out all my baby frilled dragons instead of dealing with pinhead crickets they where eating baby roaches.

Orange heads (Eublaberus prosticus), Orange spots (Blaptica dubia), Discoids (Blaberus discoidales)
These are medium sized roaches that grow to around two inches. For non-climbers they are good breeders and very easy to keep. Personally I think the orange spots are the best roach. Males have wings and females do not so they are the easiest roach to sex. The orange heads have been known to sometimes be cannibals so the need lots of protein to keep them happy. The males of these species are lighter in weight than the females and have been known to jump or fly 10-20". This is very rare but possible, so as with all roaches I use vented lids on my breeding containers. A high protein dog or cat food along with fruits and veggies makes these all good choices.

Death heads (Blaberus craniifer)
These are a larger roaches growing to 3 inches. The are also a non-climbers and I have never seen them fly. They are slower growing and don't breed quite as fast as the other, but make good feeders for larger reptiles.

6-spots (Eublaberus distanti)
These are a fun roach. As adult they look very similar to orange heads, but as nymphs they are quite different. As nymphs these look like fat little tanks. They are very heavy bodied will a very shiny exoskeleton. Most lizards are drawn straight to them. I have found them to grow much slower and take almost twice as long to turn into adults as some of my other non-climbers.

Some final comments. Most roaches live 1-3 years. They usually take between 3-6 months to go from 1/8" babies to adults. You can easily pick through them and feed them off at whatever sizes you need. I see people on this forum saying the only use mealworms or crickets. I think of all the feeders roaches are something that can solely be feed to your reptiles, but I still recommend variety. They are easy to care for and easy to breed with some heat and food.
