We were at Lums Pond State Park in Delaware last year (late Sept.) Only
there for three days and MH was covered with them on the outside. When we
left, pulled in slides and we had a "house full". Spent over 1 hour killing
them before we could leave. Hot Shot and bug spray,vacuum cleaner were used.
Were killing them for over three months. We found them dead in all the compartments, and would suddenly appear on the ceiling. Would pick them off
gently with a paper towel and drop them in a plastic bottle we had by the doorway filled with insect killer and bleach. It was a pleasure to watch them
die!! We even found them behind picture frames and inside books. Wish we could
send them back to Asia!
