A light, even spray of WD-40 on eaves, overhangs, window sills, and other susceptible spots forms a barrier that hinders the wasps' ability to adhere their nests to surfaces.
Relatively non-toxic to humans and pets, WD-40 is a safer option for pest control around the house and is more cost-effective compared to specialized wasp repellents.
Inspect your property to identify potential nesting sites such as trees, overhangs, window sills, and corners. Cautiously remove any abandoned nests, if needed.
Reapply the solution every few weeks or after rain, as its effectiveness can diminish over time. If necessary, apply additional coats to reinforce the barrier.
