For ornamental pest applications with Sevin Concentrate, you would use 1.5 oz. of concentrate per gallon of water. Since Seven Concentrate does not list this specific pest on the product label, you may also want to consider Monterey Bt Insecticide for caterpillars on ornamentals.
No, Sevin Concentrate is not labeled to control any type of root aphid. Unfortunately, there are no insecticides listed for this pest specifcally. We suggest contacting your local Cooperative Extension for assistance treating this pest that is specific to your area. This article from the UH Extension gives additional information about this pest.
Per the product label, Sevin Concentrate can be applied "as needed," but cannot exceed a certain number of applications per year. The exact number of applications will depend on what type(s) of plants are being treated and can be found on the product label.
Sevin Concentrate does treat a wide variety of insects on ornamental plants such as oak. You would use 1.5 oz of concentrate per gallon of water on ornamentals. We do recommend inspecting the plants, especially the undersides of the leaves, to help you identify what, exactly is causing the problem. We can make an accurate recommendation for you once you have identified a specific pest.
For safetly reasons, we can only recommend that you use Sevin Concentrate as instructed on the product label.
We would recommend waiting until the plants have dried after a rain before spraying Sevin Concentrate. The product label also states it is recommended to apply this product in calm weather when rain is not predicted for the next 24 hours.
The mixing rate of Sevin Concentrate is 1.5 fl oz per gallon of water for crabapple trees.
No, Sevin Concentrate should only be used to treat insects and areas listed on the product label and cannot be used to water plants.
Sevin Concentrate is labeled for eradicating leafhoppers on fruit trees, ornamentals, vegetable gardens, shrubs, and flowers.
Sevin Concentrate should be applied when the animals are not present until the application is completely dry.
Per the label, you can apply Sevin Concentrate to squash as needed, up to a maximum of 6 times per year.
Sevin Concentrate will kill many types of adult beetles, but it will not treat the larvae or grubs. We would recommend using a systemic product earlier in the season before egg hatch for the best results, such as Merit Insecticide Granules. If you currently are seeing grub/larvae damage, then Dylox is the curative treatment that works right away on these pests.
You will need to mix 1.5 - 3.0 fl oz of Sevin Concentrate per gallon of water for most applications. You can see the Sevin product label for complete usage instructions.
Sevin Concentrate is not labeled for mites that infest chickens nor can it be used in poultry coops. Permethrin SFR would be a better option.

Yes, Sevin Concentrate is labeled for springtails.
Sevin Concentrate is applied at 4 oz per gallon of water and applied with a Hand Pump or Hose-End Sprayer for chafers.
Unfortunately the Sevin Concentrate is not labeled for hookworms. There is not a product on the market that is labeled or recommended for hookworms. While some insecticides that are labeled for turf or lawn infesting insect may work, there has not been enough research to add hookworms to the product labels. We recommend thatif you have pets, they be moved out of the contaminated area for at least 6 weeks (during warm spring/summer months, longer during cool winter/fall months) and all feces be removed. Keeping the animals out of the contaminated area for at least 6 weeks should help control the infestation pattern. It is also important to remove feces from the new latrine area to avoid another infestation. Another option is to remove the contaminated soil and replace if you cannot keep out for 1 year.
Sevin Concentrate does state it should not be applied to trees larger than 10 feet tall; this is possibly because doing so would not apply an adequent amount of product to the trunk to be effective in killing insects that contact it. When treating for bark beetles, it is recommended to spray up to 15 feet high since generally they do not go much higher than that. You can use a product like Permethrin SFR to do so. Unfortunately, once the borers have already infested the tree there are not any viable treatment options as they would be protected from sprays. In cases of infestation the general recommendation is simply to protect the surrounding trees with preventative sprays with a product labeled for such a use. Infested trees will need to be trimmed and/or completely removed.
You will mix 3.0 fl. oz. of Sevin Concentrate per gallon of water for apple trees. Be sure to spray upper and lower leaf surfaces and between fruit clusters and on small limbs and trunks to the point of runoff where pests appear. Repeat applications as necessary up to a total of eight times per year for tree fruits or five times per year for small fruits, but not more often than once every seven days. NOTE: To avoid undesired apple thinning delay use until at least 30 days after full bloom.
