Pesticide Treatments for the Multicolored Asian Lady Beetle that can be Applied to the Exterior of the Home Homeowner Options

Efficacy and residual effect tests were conducted on some of the pyrethroid pesticides

(lambda-cyhalothrin, deltamethrin cyfluthrin, cypermethrin and bifenthrin) to help

homeowners with their choice of which chemical to use. During the test the lady

beetles were exposed at various time intervals to petri dish size white vinyl siding

disks that had been treated with the different insecticides. After 16-hours over 80%

of the beetles were dead or dying in all the treatments. So all of these chemicals give

good immediate control. However, the results from the long-term efficacy test showed

some clear differences. After 78 hours the lambda-cyhalothrin and deltamethrin treatments were the best with over 95% of the beetles either dead or dying. The bifenthrin treatment was next with 84% and statistically the same as the deltamethrin treatment. Cyfluthrin and cypermethrin killed only about 50% of the beetles at this time. So if your timing is good, that is you get the pesticide on your home just before the beetles arrive all of the chemicals tested should work well. However if you want to put a pesticide on early to make sure that you are covered the chemicals lambda-cyhalothrin (can only be applied by a professional pest control operator), deltamethrin and bifenthrin appear to be your best bet.
