If you suspect rat activity (droppings, gnawing or scampering noises in your walls), you'll want to try these d-CON Bait Pellets. Ideal for both indoor and outdoor use. Rats typically eat the bait and die later, normally away from the home. Open bag and place 2 2/3 tbsp. (1.4 oz.) to 4 tbsp. (2.1 oz.) of bait per rat where you suspect rat activity such as basements, entryways, drainpipes, etc. Place bait at intervals of 4 ft. to 6 ft. in appropriate locations in infested areas, as specified on the label. Inspect bait frequency and replace any eaten bait, continue to replace eaten bait until there is no consumption for 48-hours. Place bait away from water and non-targeted animals. If bait becomes wet, replace it with new bait or to prevent wetting and keep under coverings or in open ended boxes.
