The Cyzmic CS insecticide in the Carpenter Bee Control Kit will yield anywhere from 3-6 gallons of mixed solution depending upon how you mix it. The label allows you to either mix half of the 0.4 oz bottle with a gallon of water or you may use the entire 0.4 oz bottle in a gallon of water. The Delta Dust (1lb bottle) covers 1,000 sq ft.
How long it takes carpenter bees to die after they come into contact with an area that has been treated with any of the products in the Carpenter Bee Control Kit will depend on a number of factors such as the age and health of the bees, how long they spend in contact with a treated surface, and how long it has been since the area was treated. You should start to see results within a couple of hours to a couple of days.
Carpenter Bees should be treated with a residual insecticide and dust as we have in the Carpenter Bee Control Kit.
It is recommended to wait 14 days after spraying and dusting before sealing up existing holes. This allows time for the female bees to return to the nest, come into contact with the application, and spread the dust throughout the nest. If you seal the holes too quickly, this will result in bees creating new routes into the nest before coming into contact with the insecticides, resulting in more damage. Please take a moment to review the Carpenter Bee Treatment Guide for more information.
The Carpenter Bee Control Kit will not harm bird nests as long as you do not spray the nest directly. However, it will reduce the insect population in the area, which may also reduce the bird population as they will be forced to go elsewhere to find food.
The Delta Dust and Cyzmic CS in the Carpenter Bee Control Kit should not be mixed together. The Delta Dust is the only product that would be applied with the Bulb Duster. Cyzmic CS (0.4 fl oz) is mixed with a gallon of water in a pump sprayer (not included in the kit) and applied to landing surfaces, cracks and crevices and other listed areas.
Carpenter bees are normally present in the spring and possibly again in the early fall, depending on what region you are in. It would be a good idea to consult the cooperative extension office in your area for more information on the best time to apply in your specific area. You may also want to look over our Carpenter Bee Control Guide if you have not already done so.
The products in the Carpenter Bee Control Kit are safe, but keep in mind while carpenter bees are solitary bees and do not attack in groups, it is possible that you can be stung while performing a treatment. If you are sensitive to bee stings or are intolerable, we recommend that you hire a professional pest control operator to control carpenter bees. If you are not allergic but are worried about bee stings, you may want to consider purchasing and wearing a bee suit.
