Insects and Rodent Information

Mosquito Breeding Sites

The container mosquito breeds only in containers that hold water. Water-Holding cavities in trees are its natural habitat, but man-made containers are important breeding sites around homes. Good breeding sites for the container mosquito include old tires, buckets, cans, bottles, planters, tire swings, toys, or any container that holds water.

Mosquitoes Cause Disease

Inflammation of the brain (LaCrosse encephalitis) is a virus spread only by the bite of the container mosquito. The virus most often affects children under age 16. Symptoms develop within 5-15 days after being bitten by an infected container mosquito. The symptoms include headache, fever, nausea, vomiting, drowsiness, and disorientation. LaCrosse is rarely fatal, but usually requires hospitalization. Bitten children and adults get sick between July and October each year, when the container mosquito is most active. West Nile Encephalitis is an inflammation of the brain and can be caused by a viral infection. West Nile Encephalitis (WNE) is a disease caused by the West Nile virus (WNV) that is transmitted by mosquitoes. Most people exposed will not show any symptoms. However, mild symptoms may include slight fever and/ or headache, possibly with skin rash and swollen lymph glands. A rapid onset of a high fever with head and body aches, neck stiffness, disorientation, stupor and muscle weakness marks more severe infections of encephalitis. Those who may be most at risk are persons over the age of 50 and those with compromised immune systems.

Protection from Mosquitoes

Dispose of old tires, buckets, plastic sheeting, or other containers that collect and hold water. Securely screen windows, doors, and porches. Don't allow water to accumulate at the base of flower pots or pet dishes for more than a few days. Clean debris from rain gutters and remove any standing water on patios or flat roofs. Check around air conditioner units and repair leaks or puddles that remain for several days. Change water in bird baths and wading pools at least once a week. Fill or drain puddles, ditches, and swampy areas. Remove, drain or fill tree holes and stumps with expandable foam or suitable sealant. Eliminate seepage from cisterns, cesspools, and septic tanks, and standing water from around watering troughs. Remove tall weeds and grass in the yard to eliminate the mosquitoes favorite daytime resting places.

How Do Rats and Mice Get into the Home?

  • Through open or unscreened doors, windows, ventilators, and spaces around coal chutes.
  • Under shallow foundations of the house.
  • Through cracks and breaks in the foundation.
  • Through holes around electrical inlets or pipes that enter the foundation.
  • Through holes n the floor around piping (water, ect.).
  • Maybe carried in with potatoes, carrots, ect.
  • How To Keep Rats and Mice Out of the Home

There are four essentials for good rat and mouse control:


Keep garbage and refuse in tightly covered metal containers. Store food in rat proof buildings, rooms, or containers. Keep the entire premises clean. Remove shelter


Concrete basement floors and walls. Store materials in the basement on stands about 10-12 inches above the floor. Do not allow litter to accumulate on the floor behind sink, stove, or cabinets.


Do not pole coal, wood, ect. near or against walls. Steps leading into the house should be concrete or masonry. Keep stored materials (boxes, lumber, pope, ect.) up off the ground, about 10-12 inches.


Close necessary openings, such as windows, doors, and ventilators with 1/4 wire mesh. Keep doors closed when not in use. Use a good spring to make sure doors closes and spring lock. Cover all edges subject to gnawing with sheet metal or hardware cloth. Close unnecessary openings with concrete or sheet metal, such as around pipes and other outside openings. Keep floor drains tightly fastened to stop entry from sewers.


Enlarge the trigger with wire screening or card board and place trap behind boxes along walls so that rodents must pass over the trigger. When baiting the trap use peanut butter with uncooked oatmeal or tie a piece of bacon, cotton, raisins, or gum drops to the trigger.


Don't use poisons inside the house unless rodents are very numerous. A fresh supply of bait must me made available for at least 10 days. Place bait in areas where that rodents live such as wood piles, straw piles, trash, fence rows, ect. Place bait in a secure area or covered area called 'bait station'.
