DAVID R. BENTZ,                                    Appeal from the United States District

                                        ORDER

        For nearly half a year David Bentz, an Illinois inmate, was housed in a segregation
cell at Stateville Correctional Center under conditions that, if Bentz is believed, were
deplorable. He sued the warden, an assistant warden, and several guards under 42
U.S.C. § 1983, claiming that the conditions were cruel and unusual and that these
defendants were responsible. Bentz brought additional claims against other defendants,
but at screening, see 28 U.S.C. § 1915A, the district court directed Bentz to file separate
lawsuits if he wished to pursue claims unrelated to the conditions in his segregation cell.


      *
        After examining the briefs and record, we have concluded that oral argument is
unnecessary. Thus the appeal is submitted on the briefs and record. See FED. R. APP. P.
34(a)(2)(C).
No. 15-1344                                                                            Page 2

Bentz contends that the district court abused its discretion by doing so, but we reject this
argument. See Wheeler v. Wexford Health Sources, Inc., 

, 683 (7th Cir. 2012) (“A
litigant cannot throw all of his grievances, against dozens of different parties, into one
stewpot.”); George v. Smith, 

, 607 (7th Cir. 2007) (explaining that “unrelated
claims against different defendants belong in different suits”).) 1 The district court
granted summary judgment for the defendants, reasoning that Bentz had “experienced
considerable unpleasantness” but “suffered no physical harm.” We reject this view of
the evidence and remand for further proceedings.

       After the defendants had moved for summary judgment, Bentz did not respond
properly to their statement of uncontested facts. See N.D. ILL. L.R. 56.1. That misstep was
not fatal, however, because the defendants principally relied upon Bentz’s discovery
deposition as their source of evidence. Thus his account of the conditions he endured in
segregation is undisputed, and in any event we review the evidence in the light most
favorable to Bentz, the opponent of summary judgment. See Dawson v. Brown, 

, 832 (7th Cir. 2015).

        What the evidence shows is that Bentz was confined in a segregation cell from
March through August 2010. Throughout that time a large casement window (about 4’
high by 2’ wide, Bentz guesses) was stuck open by a foot, exposing him to the cold. Rain
came in through the open window, running down the wall and leaving puddles on the
floor. The ceiling also leaked whenever it rained, soaking the mattress on the top bunk
(though Bentz usually slept on the bottom bunk if he did not have a cellmate). The wall
switch for the light was directly under the window and exposed to rainwater, and
several times Bentz received a minor shock when he touched it. The toilet also was on
the same wall as the window, and if Bentz had to use the toilet when it was raining, he

          The defendants argue that we lack appellate jurisdiction because Bentz’s notice
of appeal was received by the clerk of the district court 31 days after entry of judgment,
or one day after it was due. See FED. R. APP. P. 4(a)(1). They argue that, even though
Bentz placed his notice of appeal in the mail at Stateville three days before it was due, he
is not entitled to the benefit of the prison mailbox rule because he did not declare that
first-class postage was prepaid. See FED. R. APP. P. 4(c)(1); Ingram v. Jones, 

,
644 (7th Cir. 2007). But this overly literal reading of the rule makes little sense because, in
this case, the record contains the envelope Bentz used to mail his notice of appeal. On
that envelope is a first-class postage stamp, as well the date that the United States Postal
Service received it (two days before it was due). Thus Bentz is entitled to the benefit of
the prison mailbox rule, and his appeal is timely.
No. 15-1344                                                                         Page 3

would get wet. Cockroaches and earwigs infested the cell, crawling on Bentz at night
and preventing him from sleeping. The cell was filthy, with paint and plaster falling
from the walls. The cold water faucet barely worked, and the metal stool he was given to
sit on was rusty with sharp edges.

        On appeal Bentz explicitly abandons his Eighth Amendment claim against one of
the guards, but he presses forward with respect to the other four defendants. We reject
the district court’s conclusion that a jury could not reasonably find for Bentz on these
facts. To the contrary, we conclude that a jury could find, based on the undisputed
evidence, that the conditions Bentz endured—at least in combination, if not alone—rose
to the level of an Eighth Amendment violation. We are particularly disturbed by the
broken window’s effect on the segregation cell’s temperature during the first few
months of Bentz’s confinement. Stateville is located in northern Illinois, where
temperatures in the 30s are common even in March and April. Even by Bentz’s
undisputed estimates, he was subjected to temperatures in his cell below 50 degrees (and
sometimes more than 90 degrees). Exposure to cold temperatures over an extended
period can constitute cruel and unusual treatment. See Dixon v. Godinez, 

,
643–45 (7th Cir. 1997) (vacating grant of summary judgment to defendants on claim that
failure to heat cell to temperature that exceeded forty degrees violated Eighth
Amendment); Lewis v. Lane, 

, 1171 (7th Cir. 1987) (vacating grant of
summary judgment to defendants when factual dispute existed whether cell
temperature fell below 52 or 54 degrees).

       The defendants insist that the cold alone was insufficient to constitute a violation
because, they point out, Bentz was given clothes and a blanket to mitigate the cold. We
do not understand this contention; every inmate at Stateville is given two t-shirts, two
pairs of pants, two pairs of socks, sheets, a pillow case, and one blanket—exactly what
Bentz received. The salient point is that Bentz did not receive extra clothes or blankets
after he was moved into the segregation cell with the broken window, and so, in fact, the
defendants did not compensate at all for the cold. Rather, at summary judgment the
defendants argued that Bentz could have used his commissary account to buy more
clothes or blankets if he was not warm enough.

       Even if selling an inmate protection against the cold can be characterized as a
permissible remedy, we have explained that not every effort to compensate for
inadequate heat will suffice to evade liability under the Eighth Amendment. That is
because “whether the severity of the cold, in combination with the length of time which
the inmate had to endure it, was sufficient to violate the Eighth Amendment is [a
No. 15-1344                                                                            Page 4

question] which will often be peculiarly appropriate for resolution by the trier of facts.”

. Moreover, when it was necessary for Bentz to use the upper bunk
soaked by rainwater, we doubt that his clothing and blanket provided much relief from
the cold. See Wilson v. Seiter, 

, 304–05 (1991) (noting that some “mutually
enforcing” conditions in combination may constitute Eighth Amendment violation
when each alone would not do so); Budd v. Motley, 

, 842–43 (7th Cir. 2013).
The defendants also argue that Bentz did not suffer any physical illness as a result of his
cold cell, but such a showing is not necessary. See Delaney v. DeTella, 

, 685
(7th Cir. 2001); 

.

        Beyond being cold, Bentz’s segregation cell had a light switch that was an
electrical hazard because of the water, and the cell was so infested with cockroaches and
earwigs that, despite Bentz’s killing nearly 50 a day, the insects continued to crawl on
him at night, keeping him awake. The defendants make much of the fact that Stateville
employed a pest control company to spray for bugs once each month. But evidence of a
pest control contract alone does not necessarily exculpate the defendants since persisting
in an ineffective method of pest control may be evidence of deliberate indifference. See
Sain v. Wood, 

, 895 (7th Cir. 2008) (concluding that plaintiff could not prevail
on claim of deliberate indifference where defendant had exterminated monthly and also
at plaintiff’s request when plaintiff “often saw several cockroaches crawling in his
cell“); Antonelli v. Sheahan, 

, 1431 (7th Cir. 1996) (rejecting argument that pest
control contract was sufficient evidence to defeat deliberate indifference claim where
plaintiff claimed that cockroaches were “everywhere,” “crawling on his body” and
“constantly awakening him.”). The monthly sprayings may have been rendered entirely
ineffective by the broken window, which not only invited in more pests, but caused
standing water in the cell, an enticing feature to both cockroaches and earwigs.

        The defendants also argue that Bentz could not have suffered an Eighth
Amendment violation because the insects “never bit or harmed him,” yet depending
upon the extent, duration, and kind of infestation an inmate was made to endure, a trier
of fact still may reasonably find that an Eighth Amendment violation occurred even
without a showing of physical harm. See Thomas v. Illinois, 

, 614 (7th Cir.
2012) (explaining that “a trier of fact might reasonably conclude that the prisoner had
been subjected to harm sufficient to support a claim of cruel and unusual punishment
even if he had not contracted a disease or suffered any physical pain”); Walker v. Schult,

, 126 (2nd Cir. 2013) (noting that “sleep is critical to human existence and
conditions that prevent sleep have been held to violate the Eighth Amendment”).
Similarly, prison officials who recklessly expose a prisoner to a substantial risk of
No. 15-1344                                                                      Page 5

physical injury—e.g., an electrical circuit exposed to rainwater—violate the Eighth
Amendment even if no physical injury actually results, and are subject to nominal and
punitive damages. See Smith v. Peters, 

, 421 (7th Cir. 2011).

        A jury should have been permitted to decide if the conditions that Bentz endured
for six months at Stateville constituted cruel and unusual punishment. That claim must
be remanded. We have reviewed Bentz’s other arguments, and none has merit. The
judgment in favor of Marcus Hardy, Randy Pfister, Louis Kovach, and Anthony
Robinson is VACATED, and the case is REMANDED for further proceedings consistent with
this decision. The judgment in favor of Cynthia Harris is AFFIRMED.
