Ask Mr. Pest Control
Q: Will the use of repellent products cause bed bugs to disperse further from the treatment area and spread an infestation to untreated locations?
-- Stephanie, FL
A: Studies have shown that bed bugs don’t sense dried repellent residues like cockroaches and ants and will walk across and even sit on them. However, there’s a better chance of bed bugs picking up a lethal dose from sitting on dried residue for some time than by walking across it, so application to harborages is key. They’ll still run away from a direct application of a repellent product, but they are not kept away by dried residues.
