Dealing with a dead rats in the wall.
Dealing with a Dead Rat in a Wall
Contrary to common myths told by pest control companies, rats don't eat poison bait, then run outside to drink and die, and bait does not make rats mummify, or dry up into dust, so that they won't stink.
The stench of one dead rat can be unbearable, especially when the weather warms up.
Hard-to-locate odors can sometimes be pinpointed by releasing a few flies in the room. These will soon congregate on the wall at the source of the problem, which can then be treated. If left untreated, the odor will usually disappear on its own in about a month. If the odor cannot be precisely located, apply the deodorant in the general area according to the directions on the product's label.
Poisoning
Using poison bait is the least preferred method of controlling rats. In addition to the possibility of poisoning children, pets, and non-target species, one dead rat can cause a major odor problem. Also, fleas and mites often leave rat carcasses and may infest the entire house if the carcass is not removed promptly. However if you insist on poisoning the rats please take the following precautions
If poison bait is used outdoors it must be registered for such use, applied according to label directions, and placed in a bait box. Bait boxes are designed so children, pets, and non-target wildlife cannot access the bait, but a rat can. (Bait trays and flimsy plastic or cardboard boxes are not tamper-resistant.)
Bait boxes vary in type and quality of construction, but they are usually metal or heavy plastic; those designed for rats are larger than those used for mice. Small children may be able to slide their hands inside, but the bait is tucked away in chambers, which will be out of their small hands' reach. Bait boxes can be purchased from farm a supply store, hardware store, or pest control business over the Internet.
Clearly label all bait boxes "Caution Poison Bait" as a safety precaution. Some poison-bait labels or situations may require the use of approved tamper-resistant bait boxes. If so, be sure to secure these boxes to buildings by nailing or otherwise securing them to walls or floors in a way that will not permit a person or animal to knock them over or shake the bait out.
Poison bait can be purchased packaged in a variety of formulations. Most baits contain one of several anticoagulants that prevent blood clotting, causing rats to bleed internally and die
Check bait boxes periodically to make sure the rats are taking the bait and that the bait is fresh. Rats rarely feed on spoiled bait. Because rats fear new objects, the bait may not be eaten for a few days or a week.
Remove and properly dispose of all uneaten bait at the end of a control program. Also, collect and properly dispose of any dead rats found while baiting. Pick them up, using a sturdy plastic bag inverted on your hand, and seal them in the bag for disposal with household garbage, or bury them in a location where pets or scavengers will not easily dig them up.
Dried rat carcasses and skeletons indicate a past control effort using poison bait. Many fresh carcasses are an indication that poison bait is currently being used in the area.
