Insects inside

[Olestokie]

:evil: For the last 12 months have been using the van loads, don't know where i found the time to work. But with the greater use we are finding a lot of very small ( < 0.5 mm) black crawling insects about the place, usually along edges of worktops, floors etc, We are keeping the van clean but they keep coming back.
Anyone got a recommended insect killing method, preferably one that could be dabbed into the edge under worktops, back of cupboards etc ?

Maybe one of those flea insect bombs might work. Then you have different sprays for different bugs. You may need to contact a bug buster.

They may be thunderflies - and they are a real pest.

Try puffing some ant killer in the areas affected but always clean the area thoroughly before using it afterwards.
