It is possible for rodents to stop feeding on a particular bait such as Final Blox, especially if they have a competing food source nearby or the bait is old. Be sure you are keeping fresh bait in your stations. Ideally, bait should be changed at least every 30 days if it has not been consumed. If you are having trouble with bait acceptance, then you can rotate with a soft bait such as First Strike, or a different block bait such as Gladiator Blox. We have more baiting tips in our Rat Treatment Guide here.
Final Blox Rodenticide should be used inside tamper-resistant bait stations where birds and other non-target animals will not come in contact with it.
Please keep in mind, in can take a week after ingestion for Final Blox Rodenticide to kill a rodent. There are many variables that could determine how effective rodent baiting is. Please see our Rodent Control Guide. If you have been using the same for quite some time, we recommend to swtich it up, because yes, they can build a resisitance. You could consider using a different product like Generation Mini Blocks.
