I had a previous experience last year with Orkin. You may read that if your interested on the Harrisburg Orkin branch. So I was not going with Orkin again and I had used Ehrlich in the past and was satisfied. For the life of me, I can't remember why I didn't call them again. Maybe they were pricier. Well like my momma used to say..."You get what you pay for". Last year I had a problem with carpenter ants and solved the problem myself by baiting, which Orkin didn't want to do. This year I started out very early baiting in March. I used 2 different kinds of baits, a sweet and a protein. I didn't see any ants outside (unusual and very pleasant) and very, very few inside. I thought my problem was completely solved. I was very happy. Then the first 80 degree day I went into the sunroom and there were winged male swarmers covering the windows and huge winged queen carpenter ants running around the floors. I totally freaked out. OMG. This is disgusting. They are breeding in my house! So I called Ehrlich. They, of course, tried to sell me the monthly service plan, but after the fiasco with Orkin , I said "no way. Just treat the ants". So Steve came out. What a great guy. He did the most thorough check I've ever seen. He was on the ladder pulling insulation down. Dusting everything he could and searching everywhere. It wasn't a great day to look for them because it was overcast and going to rain. They weren't even out that day. So after an hour and a half he said he was done, however he wasn't happy. He said he didn't find the nest and couldn't find any damp wood or anywhere where it looked like they really were. He said if he had actually hit the nest in the house they would have swarmed out and they didn't He even went into the nasty crawl space to the roof in a closet upstairs. God bless him. I wouldn't poke my head up there. So he was going to come out the next week to check again to see how things were going. And to bait outside, because it was going to rain that day and he wanted a dry day to bait. He also pointed out the firewood that was very close to the house and said it really needed to be moved at least 8 feet from the house and it was quite possible that there were nests in there. He also told me if the wood was there more than 2 or 3 years that he wouldn't bring it into the house unless I was immediately going to burn it because it was probably infested with all kinds of nasty little critters. I appreciated the advice and all the wood has been moved. He sprayed and dusted in between the wood as well. We also discussed baiting and he said that "Yes, we bait. It works well." Turns out they use the Advance Carpenter Ant Bait that I had bought off of Amazon as well. A couple day later on a hot sunny day I went into the sunroom and I had another swarm of males and several large, winged queens. I just kept looking and looking and noticed movement on the ceiling. I have several huge hollow beams up there that are stained a very dark brown. I noticed the movement because I saw something on the white ceiling. Sure enough, there was a load of carpenter ants going in and out of the beam and several large females were up there too. I called Ehrlich and told them I was freaking out a bit because there were so many and they sent someone out that night. It was a different fellow, I believe his name was "Jeff" but he was just a nice and just as thorough and pleasant. I swear these guys love their jobs. I don't know if I'd be so pleasant being sent out at 8 o'clock at night. He took the whole thing with good humor. He dusted the beam and we got a bunch of ants falling off and dying. He also spent quite a bit of time outside following ants around with his flashlight and dusting even more outside and putting bait down the cracks of my deck. Hopefully this will solve the problem once and for all, and I am sure if it doesn't they will work with me till it is resolved. Even though it was late, he didn't rush the visit at all. He took his time and did it correctly. And I did decide to get the year round treatment. I also asked what they put in their mouse baits and if it was a solid that the mouse can't drag around, and yes it is. And they don't get secondary poisoning from it either. So if a cat or snake eats a poisoned mouse, it won't die. All in all I was very satisfied with their professionalism, sense of humor, thoroughness and the methods employed to do the job. I also discussed the treatment of bed bugs with them because I have a crazy paranoid fear of them. They use the heat treatment method and that is the way to go. Trust me. I've researched this more than any normal person would. So I believe I'm set as far as pest problems. Like mom said, "You get what you pay for." read more
