Nature First Pest Control uses no poison baits for mouse control. We use our experience and detective skills to find and block the entry points. This method is allows us to give a one year warranty for mice invading your house.

We then use traps to eliminate the remaining mice. Our Green methods are safe, non toxic, very effective,and guaranteed.

The house mouse is well-adapted for living year-round in homes, food establishments, and other structures. Homeowners are especially likely to notice mice during fall and winter, following their migration indoors in search of warmth, food, and shelter. Once they become established inside a home, rodents can be extremely difficult to control.

In Portland, we have two different mouse species. The White Belly Deer Mouse is a native of Oregon. If you live next to a field, forest, or other green area, you have deer mice visiting your property. Deer mice are much larger than their house cousins. They are very curious and they are great climbers. I have seen these rodents run straight up a 30 foot tall chimney to reach a roof. Deer mice love to eat the dried up and live bugs that live in the attics of most homes. They will even raid yellow jacket nests and chew open mud dauber egg cases. To control them, we have to deny access to the crawl space and roof. Once block the entry points, trapping the ones that remain in the house becomes a lot easier.

The House Mouse originated in Asia and spread through Europe many centuries ago. In the 1500s they came on the ships of the explorers in what is now Florida and Latin America. They quickly spread to the northern shores of North America along with the English and French explorers, traders and colonists. Although most people consider mice less objectionable than rats, they are more common and cause significantly more damage. They are prolific breeders, producing six to ten litters continuously throughout the year.

The greatest economic loss is not due to how much they eat, but what must be thrown out because of damage or contamination. Food, clothing, furniture, books and many other household items are contaminated by their roppings and urine, or damaged by their gnawing. House mice chew through electrical wiring, causing fires and the failure of freezers, clothes dryers, and other appliances.

These rodents also transmit diseases, most notably salmonellosis (bacterial food poisoning). Other diseases include rickettsialpox, lymphocytic choriomenigitis, leptospirisis, ratbite fever, tularemia, Lyme disease and dermatitis caused by the bites of mites from the mice. Hantavirus (pulmonary syndrome) is another danger and is becoming more common.

Mice are nocturnal creatures and are rarely seen by the homeowner. The most obvious indicators of their presence are droppings (dark and pointed at both ends), sounds of them running, gnawing or squeaking, or damage to stored food or materials for nesting. Highly curious, they explore their territory daily, paying special attention to new items, or physical changes in their home range. Unlike rats, mice show no aversion to new objects. Compared to rats, mice forage only short distances from their nest, usually not more than 10 to 25 feet. When food and shelter are adequate, their foraging range may be only a few feet. For this reason, traps and other control devices must be placed in areas where mouse activity is most apparent. They prefer to travel adjacent to walls and other edges. This is a critical point to remember when positioning traps.

Mice seem to prefer cereal grains and seeds, but will catch and eat insects. When there are many food sources available, they may make 20 to 30 visits to different food sites each night, taking as little as 0.15 gram of food at each site. Sites may vary from night to night, but certain sites where the mouse feels safe are nightly favorites. When food sources are limited, mice may visit the same source 200 or more times per night, but only 20 milligrams may be taken during each visit. In all, the average mouse will consume only 3 to 4 grams or about 1/10th of an ounce, of food per night. If you suspect that you have mice in Tualatin, Tigard, Beaverton, or the greater Portland Oregon area, give us a call.
