i agree with moonshae. those backyard sprays won't help....however, if your father insists on spraying, cover your hives and have him spray at night. permethrin does last a bit on surfaces, but breaks down quickly in sunlight and weather.
a better plan for your family is the screened gazebo and the use of deet. mosquitoes carry many diseases and it is important that you protect your body from their bites. deet is very effective, but watch the product. many do not have much deet and are useless. get something that is at least 25%. i like deep woods off, but others will do fine. my horses and i share when we are out :-)
