We study a natural modification of the process introduced in [SS19], known as first passage percolation in hostile environment. Consider a graph $G$ with a reference vertex $o$. Place a black particle at $o$ and colorless particles (seeds) at all other vertices. The black particle starts spreading a black first passage percolation of rate $1$, while all seeds are dormant. As soon as a seed is reached by the process, it gets active by turning red, and starts spreading a red first passage percolation, also of rate $1$. All vertices (except for $o$) are equipped with independent exponential clocks ringing at rate $\gamma>0$, when a clock rings the corresponding red vertex turns black. For $t\geq 0$, let $H_t$ and $M_t$ denote the size of the longest red path and of the largest red cluster present at time $t$. If $G$ is the semi-line, then for all $\gamma>0$ almost surely $\limsup_{t}\frac{H_t\log\log t}{\log t}=1 $ and $\liminf_{t}H_t=0$. In contrast, if $G$ is an infinite Galton-Watson tree with offspring mean $m>1$ then, for all $\gamma>0$, almost surely $\liminf_{t}\frac{H_t\log t}{t}\geq m-1 $ and $\liminf_{t}\frac{M_t\log\log t}{t}\geq m-1$, while $\limsup_{t\to \infty} \frac{M_t}{e^{c t}}\leq 1$, for all $c> m -1$. Furthermore, if we restrict our attention to bounded-degree graphs, then almost surely as $t\to \infty$, for all $\gamma>0$, $H_t$ is of order at most $t$. Moreover, for any $\varepsilon>0$ there is a critical value $\gamma_c>0$ so that for all $\gamma>\gamma_c$, almost surely $\limsup_{t}\frac{M_t}{t}\leq \varepsilon $.
