There are many variables contributing as to how long Sevin Concentrate stays on a plant. Please review the product label. You will find a very helpful table listing the Pre Harvest Interval and number of applications allowed for each plant. You can reappy 14 days after initial application.

Sevin Concentrate is not labeled to be used on citrus trees so we cannot recommend it for this use. We would recommend a product with neem oil, such as Bonide Need Oil Concentrate. It is labeled for various pests on fruits, vegetables, flowers, etc.

Sevin Concentrate is best used to protect healthy trees from the listed borers on the label. Unfortunately there is no easy solution when it comes to pine borers. Infected trees should be cut down (before the newly hatched beetles fly out of the trees in the spring/summer) and the wood burned or chipped, while other still healthy trees should be sprayed annually to protect them. Because of the natural boring behavior of the beetle they are protected from topically applied insecticides and systemic insecticides (those injected into the tree or applied as a root drench) have proven ineffective for pine beetle infestations. Healthy trees can be protected before the beetles attack by topically spraying them with a synthetic pyrethroid like the Sevin. The tree should be sprayed from the ground to 15 ft up the trunk to prevent future infestations.
Sevin Concentrate is labeled for both psylids and leafminers. The exact amount of time it takes to kill an insect will depend on a number of factors, such as where the insect is in its life cycle and how long it spent in contact with a treated surface. You should start to see results in a few days, but reapplication may be necessary per the product label, especially if the infestation is severe.
Unless the bird consumes Sevin Concentrate directly, it would not be affected. For there to be even a chance of a bird or other animal being affected by Sevin, it would have to eat at least its weight in insects that have died from it.
Sevin Concentrate is not labeled for use on lawns. You can use Sevin Granules on lawns for ticks and fleas. For fleas, you would use 4-9 lbs per 1,000 square feet. You can apply up to 3 times a year with at least 7 days between applications. Keep in mind that Sevin is just a contact kill, so it will not have residual effect for fleas, ticks, or other listed pests. For a residual granule to use instead, you could use Talstar XTRA Granules every 30-60 days. Please see our Flea Treatment Guide and Tick Treatment Guide for more tips on eradicating these pests.
