after doing my second nest check, I have one gourd with four beautiful eggs. Three other compartments have green leaves but I only see 6 martins. Did I apply this right .......with a 1/4 teaspoon of sevins in a spoon I placed it against the back side of the gourd and dumbed it between the gourd and the nest? I did this to all four compartments. Thanks for all the help offered here and I'm sure many dumb questions to follow.
