How to use Crossfire when I already have a mattress encasement on?
I'm in the UK and have had Bedbugs for about a year. Have had exterminators come out and visit 4 times, with chemicals like Pelgar Cimetrol Super and Cimexa being used.
Before I called the exterminators last year I encased my mattress in an encasement and haven't taken it off since.
If I'm going to use Crossfire, do I spray on the encasement as well as the edges of the bed etc?
