Tenant says no to roach spray

[Allana Alex]

Tenant contacted me and complained that she has roaches and water bugs in her apartment.  I spoke to my other two tenants below her who informed me that they do not have a roach problem in their apartment so problem is clearly this upstairs tenant.

I told her i would have a professional exterminator come to her apartment and have it sprayed.  She told me that she did not want her apartment to be sprayed because her 20 year old daughter has asthma.  Instead, she would like me to provide her with combat roach baits.

Is this asthma story a viable reason to decline my attempt to immediately resolve this roach issue?  I want to resolve any roach issue as expeditiously as possible.
