Snap-type mousetraps are effective
Set mousetraps correctly
Snap-type mousetraps, when well placed, can be an effective way to rid your house of mice. Common mistakes are poor placement of traps and using too few of them. Place snap traps along walls in areas where you've seen the telltale brown pellets. The best technique is to set two traps, parallel to the wall, with the triggers facing out. While mice can jump over one trap, they can't jump two. Favorite baits of professional exterminators are chocolate syrup and peanut butter.
Deprive bugs of moisture
Dehumidify and clean up cobwebs
You can virtually eliminate spiders in your basement by using a dehumidifier to maintain a 40 percent humidity level and vigilantly sweeping down cobwebs whenever they appear. Keep the basement window sills brushed clean too. In a matter of weeks, the spider population will die down significantly.
