Calling.
The number is (888) 686-4821. Overnight, weekend and holiday calls reach a person too, and a same-day trip gets scheduled whenever there is room.
It helps to have the street address, a short description of what you saw or heard and the date it started. Mention any children, pets, vehicles or detached buildings that could be involved.
Emailing.
Send photos or slower questions to contact@prorodentcontrolkaty.com. A reply by email takes longer than a call, so use the phone if the noise is happening right now.
There is no contact form on this site, on purpose. A conversation with a person gets a visit booked faster than a box to fill in.
