Hi Yield 38 Plus is a good product, however, it is not labeled for spiders.
We would recommend a product called Onslaught FastCap Spider and Scorpion Insecticide. It is labeled for mosquitoes, spiders and ants. This would be an excellent product to use in your backyard. It can also be used inside as well as a crack and crevice spray if needed. It has a quick knockdown as well as a residual of 30 days.
You want to keep the product at least 5-10 feet outside the drip line of anything edible when treating with Hi-Yield 38 Plus Insect Control. We do offer products that can be applied to fruit trees for boring insects. Please click on the link below for those products. Please refer to the product label for specific application instructions. Please let us know if you have any questions.

Mixing Hi-Yield 38-Plus Insect Control - 38% Permethrin at 1.6 fl uid ozs. (3 1/4 Tablespoons) per 1 gallon of spray solution to make a 0.5% spray emulsion.
To prevent infestation of Ornamental Trees and Woody Shrubs, spray the bark to the point of saturation, but do not let runoff occur. Repeat treatment every 21 days during early Spring until Mid-Summer
Hi-Yield 38-Plus Insect Control - 38% Permethrin should be mixed at 0.8 fluid ounces per gallon of water. While you could use the Hi-Yield 38 Plus for scorpion control, a better option would be something that sits on the surface better and lasts longer. Cy-Kick CS and Onslaught FastCap Spider and Scorpion spray are the two best options for scorpion control. Both products are easy to mix with water and spray around the home. Not only will they kill scorpions, but will also kill all the other insects present around your home that they are feeding on. Since scorpions have thicker skin, you will need to spray a wider barrier around your home. Spray 2-3 feet up on the side and a minimum of 6 feet out on the ground. Make sure to also spray other entry points of the home like where wires/pipes enter the house, window frames and door frames.
Hi-Yield 38-Plus Insect Control - 38% Permethrin is not labeled to treat for Bird Mites. If you have had the pest identified as Bird Mites you can use Onslaught and Sterifab. You would mix 1 ounce of Onslaught per gallon water. Sterifab is a great contact killer and disinfectant for all surfaces inside the home including furniture, bedding, rugs etc. For helpful tips for controlling bird mites, please reference our article on How To Get Rid of Bird Mites.Or Rodent and Bird Mites in the Home.
