Bed Bugs \u2014 The Most Dreaded Household Pest<\/strong><\/h2>

Bed bugs hide in mattress seams, electrical outlets, and along baseboards. They can live for months without a meal. Their stronger exoskeletons resist many off-the-shelf insecticides.<\/p>

DIY foggers often make things worse. They scatter the bugs into walls and other rooms. The standard pro solution is heat treatment or targeted chemical work. Most homes need more than one visit to clear them.<\/p>
