My husband did the trench method. He said he was so tired that he replaced back the untreated soil and sprayed it with Termidor SC the next day and it rained a few hours after he did the spray. Is it still okay if he did it that way? And one more thing, he only sprayed on the front of our house with the landscaped area and did not do trenching. Is it also fine that way too?
Spraying Termidor SC on the surface of soil is not going to offer a protective barrier like the trench and will only work for the general pests that contact the soil surface. Termidor binds to the soil that it is applied to and needs to be used in a trench 6 x 6 inches to offer the best protection. It also does not move through the soil after rain. Termites do not actually contact the surface so it would be best to go back and complete the trench in those areas that have not been done.
