Bedbug Movement Throughout Apartment Buildings

from NPMA

Bedbugs (Cimex lectularius) can be extremely difficult to control in multifamily housing buildings due to their propensity to move from one apartment into neighboring units. A trio of Rutgers University researchers, Drs. Richard Cooper, Changlu Wang, and Narinderpal Singh, investigated bed bug movement within and between apartments to see how far bedbugs moved in this setting. Using a well-established monitoring technique, bedbugs were marked non-invasively, released in 6 apartments and captured to determine how far they traveled from their original apartment. Marked bed bugs were found in neighboring units in 5 out of the 6 apartments where bedbugs were originally released. The second component of the study was to determine how long bedbugs survived in a vacant apartment (without a host). At the conclusion of the study (155 days), adult bedbugs were still found alive, though early instar nymphs died after 134 days. The larger the initial population, the longer bedbugs were able to survive in the absence of bloodmeals.

This paper was published in the most recent volume of the journal PLoS ONE under the title, “Mark-release-recapture reveals extensive movement of bedbugs (Cimex lectularius L.) within and between apartments.” more
