No. As long as your gate is unlocked and your pets are inside, our service professional can provide service. Our trained professionals will obtain any information pertinent to your location (i.e. locked gate) when you sign up. nnYour service professional will leave a door hanger upon completion of your treatment so you will know your yard has been serviced. Information on this door hanger will include the date and time of service as well as any comments and helpful hints from the service professional to help you keep your yard as uninviting as possible for mosquitoes, ticks, and fleas.
