I shop at Lesco and they recommended i use Cross Check and orthene, Which i did only to find out while yes it did kill 95% of the existing infestation they came back in a bad fashion within 3 weeks. Please help! What would you guys recommend? I just really want to do my Sub right and do a great job for his customer. Thanks in advance!
As you can see from this link from Texas A&M, repeat applications are necessary. http://insects.tamu.edu/extension/pu.../eee_00022.cfm
The good news is that you are at the end of their cycle.
A licensed applicator should know this or know how to find the information before taking action.
Google is a wonderful tool.
