It is easy to verify whether a bed bug has been exposed to Aprehend® during follow-up visits. Once Aprehend® bed bug treatment has been applied, any bed bugs that are found (living or dead) can be placed in a resealable plastic bag on top of a wet paper towel.
If a bed bug was exposed to Aprehend®, the fungus will emerge on the outside of the bed bug and produce white “fuzz” under high humidity conditions. This may take up to 7 days. Sporulation indicates that Aprehend® is active and working to eliminate your bed bug populations.
