Some of the more common rodent killers include:

  • Snap Traps – where the spring triggered trap snaps on the rodent’s neck hoping to kill it.
  • Electric Traps – kills by shocking rodent with electricity (this is the most humane method to kill rodents).
  • Drowning – works by leading rodents to fall into a bucket of water and drown (this is the second most humane method to kill rodents).
  • Bait poison – works by luring rodent into mistaking them as food and consume the poison.
  • Glue Traps – traps rodent to glue pad while they starves to death (this is the most cruel way to kill rodents).

Note: No glue trap has been featured in this article as we think it is a very cruel way to kill rodents.

Each method comes with it’s pros and cons. When deciding which method to use, be sure to consider the seriousness of your rodent problem as well as the location of usage.

Final Thoughts

Each rodent killer comes with its pros and cons.

Traditional traps like snap traps have longer longevity than electric traps but might not be more effective or easy to clean-up after.

Bait poison is more hands off but rodent might die in secluded area that’s hard to find, hence resulting in odor.

In our opinion, electric traps is the most humane way to kill rodent as rodent simply gets lure into the box and gets electrocuted.

Sidenote: We strongly suggest to kill rodents instead of setting them free as they might return or worse, infest other households.
