Permanent rat elimination requires three things working together: killing the existing population with bait or traps, cutting off food and water sources, and sealing entry points so new rats can't replace them.
No single product eliminates rats permanently on its own — rats are neophobic, reproduce fast, and will recolonize any space that still offers food, harborage, or access. RatX pellets or bait discs handle the kill side by blocking thirst signals in the rodent gut, leading to dehydration and death within 3–5 days. But long-term results depend equally on exclusion: steel wool, hardware cloth, and caulk in gaps larger than a quarter-inch. Skip that step and the infestation returns.
- RatX lethal dose per rat: 40–60 grams (1½–2 oz), consumed across multiple feedings over 3–5 days.
- Rats can squeeze through gaps as small as ½ inch — exclusion must address any opening that size or larger.
- RatX's sodium chloride ingredient mummifies carcasses post-death, reducing decomposition odor by up to 90%.
- Rats require 3–5 days of consistent bait access before the dehydration mechanism reaches a lethal threshold.
- A 1 lb bag of RatX pellets contains approximately 450 grams — enough to address roughly 9 rats at 50 grams per rat.
