Fertilome Tree and Shrub Systemic Insect Drench is not labeled for use on mosquitoes and we do not have any research to show this type of application would be effective.
Talstar is our most popular selling product for mosquito control. It is a liquid concentrate that you mix with water and apply using a sprayer. You will need about 1 oz of product for every 1,000 sq ft of space you need to treat. The key is to apply it to all shrubs, trees, and other foliage around the house or patio where you are trying to provide relief. It should be directed not only on top of the leaves and plants, but on the underside of the leaves as well which is where the mosquitoes hang out. Talstar should be applied every 30 days for optimum control.
Fertilome Tree and insect drench is a great insectide. However, to treat the beetles and many other insects in your lawn we recommend using Talstar P. Talstar P would be a great product for you to use for thebeetles and the other insects on your property. Talstar P can be used in your yard, around the perimeter of your home and also inside your home when needed and it is safe for use around pets. Since grubs live underground they must be treated with a product that will target them where they live. We do have several products that are specifically labeled for grub worms on our website: Grub Worm Control. We also recommend that you contact your local cooperative extension office and inquire about the best time to start treatments for grubs in your region.
When using Fertilome Tree and Shrub you should treat mid-fall and again in the spring with a a soil drench. You may need to moisten the ground prior to the treatment, use the higher volume of water as recommended on the label and keep the soil moist for the following 14 days after the treatment to encourage the tree to trans-locate the product. We are not sure where you saw that we do not recommend Fertilome drench for EAB but we think it is a fine product for this pest.
