It has been sunny and hot and working great for about 2 weeks then they start appearing again. How often can I reapply?
When applied at the low rate of 0.33 fl oz per gallon, Bifen IT can be reapplied every 7 days. Applications made at the high rate of 1.0 fl oz per gallon, retreatments can be done every 30 days.
Please review the Mosquito Control section on the product label for more information.
