We have had Bulwark now for about 7 years and they have been great. We recently moved out to an area where we have fields accross the street. After the recent potato harvest all the crickets decided to join the neighborhood. If you have ever had crickets hopping all over the yard, eating up your garden, crawling into the house, getting up under the kitchen cabinets and chirping all night long you know how annoying a plague crickets can be. Anyways, we told our tech Bill Kelty about the problem when he came out for our regular service last week and he said he would take care of it. AND, guess what? He did. No more crickets. Thank you Bill!
