What drugs will make rats less cautious/sensible and/or more hungry so they'll go to my snap traps more?
What dosage and how do I deliver it to the rats?
Background info:
The rats trapped in my crawl space I imagine have limited food, if any.
The snap traps are well coated with peanut butter scent but the process is very slow -- one by one.
They have rat mites (blood-sucking parasitic barely-visible mites) and I want them out ASAP.
It's been several months because:
- They reproduced down there.
- One of the vents got broke open again so a second batch got in. I don't know how many. 25 rats have been trapped so far (2 today and I hear more).
I've checked the house so well. Sealed up with caulk and expanding foam every hole. Checked the roof. Sealed wire mesh on all the plumbing stacks and exhaust vents on the sides of the house.
There's really nothing else. I'm positive it was the broken foundation vent that let the new ones in. But now that everything is sealed securely and won't be broken open again, I think it's only a matter of removing the existing rats.
I don't want to poison them because then they'd die inaccessibly and their mites would swarm the house. They have to die in the traps that I check several times a day, so they can be removed before the mites spread.
