Even if you could legally acquire DDT, it would likely be ineffective against modern bed bug infestations.
: Because modern pyrethroid-based sprays target the same part of the insect's nervous system as DDT, bed bugs that survive modern chemicals are automatically "pre-adapted" to survive DDT. Effective Legal Alternatives where can i buy ddt to kill bed bugs
The EPA has registered over 300 products for bed bug control across seven chemical classes: DDT - A Brief History and Status | US EPA Even if you could legally acquire DDT, it

The Environmental Protection Agency (EPA) banned the pesticide in 1972 due to its severe environmental persistence, toxicity to wildlife—notably bald eagles—and potential human health risks, including cancer. The Futility of DDT for Modern Bed Bugs carry genetic mutations that make them highly resistant
: As early as 1947, bed bugs began showing resistance to DDT. Today, approximately 90% of bed bug populations in the U.S. carry genetic mutations that make them highly resistant to DDT and similar nerve-agent pesticides.
Since bed bugs are notoriously difficult to eliminate, experts recommend an "Integrated Pest Management" approach using registered products and physical methods. 1. Professional and Consumer Insecticides
