Bed bugs typically will not go away on their own. If there are no humans or animals around, they will need to leave to find a host for feeding. But otherwise, bed bugs can live for several months to a year, and the adult females can lay hundreds more eggs in their lifetime. An infestation is only likely to get worse without hiring an exterminator.

Yes, crawl spaces can attract bugs, especially since moisture tends to build up in the space, and moisture attracts pests. A good way to prevent pest infestation in your crawl space is to install a vapor barrier—called crawl space encapsulation—on the interior to seal the space, along with a French drain or some other kind of foundation drainage system outside to keep runoff out of your crawl space. You can also seal foundation cracks and repair damages to cut off access to pests.

Like many pests, fleas hide in dark, sheltered areas, including in the bed. They will seek out crevices in a mattress, so they have easy access to their hosts (you and your pets) as well as somewhere that is warm and hidden. You may also find fleas hiding in carpeting and other furniture.

Setting up an animal trap in your yard largely depends on where you live and the type of critter you're dealing with. In many states, trapping nuisance animals like squirrels, rats, or raccoons is allowed, sometimes without needing a permit. However, certain wildlife species are protected, and not all states have lenient catch-and-release regulations.

Before placing a trap, check your local laws to avoid fines or other legal issues. Some areas allow DIY trapping, while others may require professional assistance. Most areas require a professional to relocate the animal once trapped. Consulting a pro ensures you handle the situation responsibly, humanely, and within the law.
