this was our 1st time using Bulwark and my Husband and I were amazed! He sprayed so heavy that the scorpions came out and we took care of them on the spot there was about 8 or more!! Overall Brendon did an excellent job and really listened to us and helped us understand roaches and how they survive and how to get rid of them. We were using another company for 5 months and they never killed off anything and we are 3 days after he sprayed using Bulwark and we have found a dead scorpion by our garage and a lot of dead roaches so that is proof Bulwark works!! Can not wait to have no more scorpions!! Hooray! Thank you Brendon!
