Roof rats can carry a variety of pathogens and parasites, including salmonellosis (food contamination), leptospirosis, trichinosis, rat-bite fever, murine typhus, plague, and toxoplasmosis. Diseases can be spread via urine, droppings, or saliva. To prevent transmission, it’s essential to promptly address a roof rat infestation and avoid direct contact with the animals where possible.

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.

Fruit flies aren’t harmful by themselves, and they can’t bite or sting you. They can, however, spread bacteria around your home and can be a nuisance to live with. That’s why it’s important to eliminate fruit fly infestations quickly and enact preventative measures to keep them out of your house.

The number of treatments required to eliminate bed bugs varies depending on the severity of the infestation. Most cases require two to four treatments within a three- to six-week span. However, a small infestation might only need one inspection and one treatment visit. In contrast, severe cases or large homes may require an ongoing plan with quarterly, monthly, or semi-monthly visits from an exterminator for up to a year. To get rid of bed bugs as quickly as possible, it's best to investigate and treat them at the first sign of an issue.
