How to get rid of them? I’m losing my mind

Hi all,<br><br>I live in Massachusetts and I’m at my wits end. I have a mudroom that is being heavily infested with western conifer seed bugs. I have tried sealing any gaps I can find, using the orange peel spray, as well as other products. I get them under control, then a new wave comes in. I have even tried essentials oils. I desperately need help. I have a 1 and 2 year old, and I’m terrified of leaving my kids down there and then they find one on their pacifiers or in their beds. Does anyone know of any long term solutions? What bug sprays would you recommend? <br><br>I can’t stomach going down into that area of my house. I have tried to be strong but today I cried. I just can’t do it anymore. I believe that the infestation is coming from my fireplace as it looks to be leaking ever so slightly. I believe this is where they are getting in, but I’m still losing my mind. If anyone has any advice it would be greatly appreciated.<br><br>-A very stressed Mom
