    Q
    How long after Cynoff was applied to a shower area can the shower be used?
    My apartment had a pretty serious ant infestation mostly its bathroom. The exterminator deployed Cynoff to the corners of the bathroom and along the baseboards. The exterminator also deployed Cynoff in the shower along the cracks of the floor of the shower where the tile met the shower basin, as that’s where the ants were coming from. It’s been 24 hours since the Cynoff was deployed. Can we begin to use the shower and bathroom?
    A

    Cynoff EC can be applied indoors in cracks and crevices only. It is not labeled for use directly inside the shower or in or drains.  We would recommend thoroughly cleaning to remove the product from the area.  For labeled areas it is safe to return once dry, typically an hour inside. Please see the label for full application instructions.

    Q
    We are in Cherry Valley, Ca. 92223. We have black widows, ants, and mice. What do you recommend for each?
    We live on 5 acres, have chickens, dogs, and cats. We have used your Cynoff EC and are not sure if that is the best application and whether or not it is safe for the chickens.
    A
    Cynoff Ec is a great product to treat Mice and Black Widow spiders. Please contact FMC to make sure exactly where you can apply this product, as California does have restictions. 800-321-1362. We recommend using Mouse bait stations like protecta RTU stations and then putting mouse bait in the stations like Contract Blox. Please see our Mouse Control Page.

  • Asked by Jesse from Columbia Falls
    04/04/2020
    Q
    I have been told that Cynoff EC is good to use for pine bark beetles.
    What would your mixing recommendations be for us on spruce and fir trees? Also suggested time to apply. I live in N.W. Montana.
    A

    Cynoff EC is only labeled for elm leaf beetles it would not be recommended for any other type.

    The best product for pine bark beetles is Permethrin SFR 36.8%. Trees can be treated from April through to the end of June however trees must be sprayed protectively, before the beetles fly and attack. Spraying trees after they have been attacked will not save them. Once the tree is infested there isn't much you can do other than chop down the tree and burn it to try and prevent the current live ones from getting into any neighboring trees. 

    The tree should be sprayed from the ground to 15 ft up the trunk to prevent future infestations.

    Q
    Will cynoff kill fire ants
    A

    Cynoff EC is not labeled to target fire ants specifically, it only lists ants in general.  Our informative guide on How to Get Rid of Fire Ants is a great resource, which provides detailed treatment recommendations and links to related products.  Individual mound drenches with a product like Talstar P, or baiting with a product like Extinguish Plus Fire Ant Bait (providing the ants are foraging) are the most effective treatment methods for successful fire ant elimination.
