The Acephate gets used at a variety of rates depending on the insect you are treating for. You will use up to 1 lb per acre and the water you dilute it with will be depending on how much you need to cover your area. The water in this case acts as a carrier, so whether it takes you 10 gallons or 50 gallons of water to cover an acre of area adequately, both are correct so long as you are using the correct amout of acephate over that acre.

Acephate 97UP Insecticide is not labeled to be used inside homes for roaches and is not safe to do so.  

One of our roach control kits would be recommended for roach control. These professional kits includes non-staining, low odor concentrated insecticide for spraying the outside perimeter of the home and inside underneath appliances, behind cabinets, under toilets and sinks, etc. You'll also get Roach Bait Gel to help get rid of those roaches that like to hide. Baits can be applied up high in the kitchen in the corner of cabinets and in cracks and crevices in kitchens and bathrooms. The bait contains a slow-acting poison that attracts and kills feeding roaches, who also spread the bait to other roaches by contact or by sharing food. Finally, an Insect Growth Regulator is offered which will stop roaches from laying eggs, helping to halt the infestation. The combination of an IGR with roach bait is a highly effective roach control strategy that is widely used by pest control professionals. The insecticide must be applied with a 1 gallon pump sprayer.

Acephate 97UP is not labeled to control white pine weevils.  The standard approach to manage white pine weevil is to spray insecticides in spring. This treatment is directed at the overwintered adults to kill them before they lay eggs. Current insecticides useful for this treatment would include products that contain bifenthrin (Talstar), cyfluthrin (Tempo) or permethrin (Tengard). Rates of use should be to the high-end of what is labeled, such as for bark beetles or borers. Timing is very important but difficult to determine. Sprays should be applied shortly before adults begin to feed on the terminal and lay eggs. You can contact your local cooperative extension office and speak to the master gardener on staff who can help you determine the correct timing. Treatment of the top of the tree during midsummer, after adults have emerged from the wilted terminals, can kill weevils as they feed in this site, reducing overall numbers that may cause problems in the subsequent year. Also, as many weevils crawl to the trees in spring, treatment of the lower trunk at the same time spring terminal applications are made may also help kill some of the migrating overwintered insects.
