How do you find a carcass in a wall?

To find a carcass in a wall, start by identifying unusual odors or signs of decay, as these can indicate the presence of a dead animal. Use a flashlight to inspect areas where you suspect the carcass might be, looking for discoloration or droppings. You can also tap on the wall; a hollow sound may indicate an opening. If necessary, a professional pest control service can help locate and safely remove the carcass.
