I used these initially for rental property in Atlanta where there was a significant rodent problem. I used the Fastrac Blox in the beginning and found them to be effective. However, I later experimented with the Gladiator Bait Blox, which has the same active ingredient as Fastrac. I put Fastrac Blox on one side of the Bait Station and Gladiator Blox on the other side of the same Bait Station. Interestingly, the rodents ate all of the Gladiator Blox first. After that buffet was gone they turned to the Fastrac Blox. There was definitely a preference for Gladiator Blox. The Fastrac have a fishy smell, while the Gladiator is more of a sweet odor. That could explain the preference for Gladiator.

Company quickly acknowledged that rods and locking screws were inadvertently not shipped. They sent the missing parts by Priority Mail. My rat problem has been eradicated and I have reduced the number of bait stations and bait to a minimum and will monitor to see if they reappear. I live out in the country and Contrac Blox is very effective in controlling my roof rat problem.

Plagued with chipmunks running all over our property, procreating faster than rabbits, we tried every trap imaginable: two different brands of spring traps and Hav-a Heart. We managed in an entire season to catch only one chipmunk and one squirrel. The chipmunks had such a delicate touch that they were able to eat the bait off the trigger without springing the traps!! By chance I became aware of the Protecta traps and bait. I purchased the 6-station kit with the pail of Contrac Blox. For the first week, there was little action. THEN, the little devils seemed to discover the stations and they began to eat the Blox so quickly that, in the case of two stations, I had to refill them every three or four days!! There are no dead bodies laying around, for they must go back to their holes to die; however, beyond any doubt, there are a lot fewer chipmunks than we had before!!! Viva Protecta and Contrac Blox!!!!!!!!
