This is not good, and, unfortunately, not uncommon in the pesticide industry. I got a message the other day from a lady who lives in the mountains. She was getting bitten by something and sent me a photo. They thought it was a bed bug. Actually it may be, but where she lives it could also be a swallow bug or bat bug as they both are very similar and actually closely related to bed bugs. She called an exterminator. I told her to check and make sure the exterminator had a microscope in his truck and could identify them. He couldn’t. He said he wasn’t a specialist in bugs, just an exterminator. He would have treated her house for bed bugs, which would be completely ineffective against swallow or bat bugs. It seems to me that any exterminator should be a specialist in bugs before they start spraying their pesticides anywhere. This would be like going to a dentist and the dentist saying he is not a specialist in teeth, he is just a dentist. Or a mechanic and him saying he is not a specialist in cars, he is just a mechanic. If you have to use an exterminator, please make sure they are specialists in bugs before you let them spray pesticides anywhere. This is why we have so much sickness and pesticide pollution, because we have pesticide applicators who have no idea what they are doing. It is just about the spray and pray method where they spray pesticides along a wall and pray they kill something. Any competent company will be able to positively identify any pests you have. If they can’t, don’t hire them. Please be careful if you want to hire someone like this. And in the real world, you probably don’t, you can control most pests yourself. I will be happy to help you if you want.
Anyway, the lady is going to send me samples of the bugs and I will identify them for her and tell her how to manage them herself without using an exterminator.
