LD50 = ~3.3 tsp
Reading the MSDS, it takes greater than 5K mg/kg to cause 50% of the target population to die. I am witnessing 0.25 tsp being consumed in the bait station over the past 4 days. Am I misunderstanding how much is needed for an effective kill?
The true amount needed for an effective kill will of course depend on size of the rodent, current health of the rodent, and population of the rodents in the area. .25 tsp may be enough for a younger rodent feeding on the bait. You should always keep enough (Terad3 )bait in the station for the population that is present. They may eat very little one night, and a lot the next night, so it is important to keep an eye on the bait. Also, you want to make sure there is not some other food source out that is more attractive to them than the bait blox. Little competition of food will make the blox more attractive and more effective.
