The bait blocks worked well in our attic where we had a persistent rat problem. We placed them in corners and noticed activity stopped within a week. The packaging is sturdy and the bait stays fresh. No insects were found inside the blocks after several weeks.

We used these in a basement area with mice. The bait was effective and the s-methoprene treatment kept it from being infested. It took a few days for the mice to consume it, but after that, we didn’t see any more activity.

Great product for targeting warfarin-resistant rats. We’ve had issues with previous baits failing, but this one worked. Easy to place and the blocks last longer than expected.
