TPCA Members,
 
The US Department of Homeland Security has put out a memorandum on identification of essential critical infrastructure workers during the COVID-19 response. Below is a link to the memorandum.
If you search the document for “exterminators”, it will lead you to the Public Works section of the document where you’ll find exterminators considered to be Essential Critical Infrastructure Workers.
"Workers such as plumbers, electricians, exterminators, and other service providers who provide services that are necessary to maintaining the safety, sanitation, and essential operation of residences"
If you have any questions please contact the TPCA HQ Office at (512) 954-9664. 
Sincerely,
Todd Kercheval 
Executive Director
Texas Pest Control Association
