I spray wasps with WD 40 when it is necessary to remove them. I
think it penetrates their exoskeleton. Whatever the reason, it
drops them. I haven't sprayed WD on solar modules. <br><br>
I minimize the use of toxic chemicals due to the environmentally caused
cancer epidemic that is pretty much world wide now. A biocide for
insects is a biocide for humans. <br><br>

She's pretty set on getting rid of them. I'll recommend hosing them down
with water at night. I think she's going to want to go chemical, though.
I'd love to hear anyone's experience with sprays damaging the backsheet
or not.<br><br>

<dd>Hi Wrenches,<br><br>
<dd>I have a client who has developed quite a problem with wasps behind
her array. Does anyone have experience getting rid of them? I'm afraid of
the possibility of sprays damaging the backsheet. Is that a legitimate
concern? <br><br>
<dd>Thanks,<br><br>
