Sometimes rats and mice get indoors, creating a nuisance. They damage property, contaminate food and transmit deseases. The following suggestions should help in eliminating rodents in your home.
Cleanup inside and store food in glass or metal containers. Floors should be swept often to deny rodents food. Garbage should be placed in trash cans with lids. Food and pet food should not be left out overnight unprotected. Mice hoard food in inaccessible places, so removal of known supplies may not reduce mouse infestations immediately. The control of weeds around the outside entryways is also an important factor.
Traps should be placed along the walls and in paths where rodents travel. Beware of trap-shy rats and mice, and leave traps un-set until bait has been taken at least once. It is better to use too many traps than not enough. Traps do not have to be washed after a catch. Some recommended baits for traps are: peanut butter, pineapple, nuts, doughnuts, cake, fried bacon, raisins, chocolate and gum drops. Rats are attracted more to ground meat or fish.
Poison bait can be used along with trapping to increase capture and kill. There are some very good poisons available. Warfarin, Pival, Fumarin, Chlorophacinone, Bromadiolone and Cholecalciferol. BE SURE TO USE THESE ACCORDING TO LABEL INSTRUCTIONS. Mice tend to nibble so expect a longer period of time to get control of them with poison. Also, poison may cause rodents to die in inaccessible areas leaving unpleasant odors of decaying carcasses. Children and pets should be kept away from the poison baits.
4. Rodent Proofing
Rodent proofing is a vital part of a complete rodent control program. The objective is to close all present and potential openings which may serve as entries for rats and mice. This means changing building details to prevent entry. It is important not to seal rodents indoors until baiting, trapping and removal is completed.
Inspect first! Begin with a thorough inspection of the premisies and locate openings larger than 1/4 of an inch and openings where utilities enter. Check floor drains and sewer pipe grates. Make sure doors, windows and screens fit tightly. Other possible entry points are transoms and letter drops.
The materials for rodent proofing should be rodent resistant such as sheet metal, heavy wire mesh, concrete, brick and mortar. Steel wool is a good substitute for plugging holes.
Rodents urinate everywhere and are a source of disease in living quarters. Rodent droppings can get distributed by HVAC systems that are located in crawlspaces and attics when they dry out and become aerolized. There have been instances of individuals contracting Hantavirus when exposed to droppings from rodent nests in flood situations. Humans can become extremely ill and in some cases die from the effects of Hantavirus.
Exercise care and be diligent in your efforts to control these vermin.
