This is not the result of a virus, and not a hack.
Unfortunately email spoofing is a fact of modern internet life. We are doing all we can to not abuse email systems and protect everyone's privacy. None of our systems or emails have been breeched in any way. Spammers simply see our name on many messages and therefore are borrowing the name "Expert Pest Control" to send spammy links to compromised accounts.
If you see any emails with the name "Expert Pest Control" but it's not from someone @expertpest.com for example colin@expertpest.com, please let us know and report it as spam in your email system.
I wish there was more we could do to prevent this from happening. Thank you for understanding.
